Choosing among the best jointers for long boards comes down to one measurement: how much continuous cast iron sits under the workpiece. A board rests on the infeed table, drops roughly 1/32 inch onto the cutterhead, then lands on the outfeed table. When the board is longer than the two tables combined, the ends drop below the cutterhead line, and you get taper, a hollow at the far end, or a twist you can only fix with a lot more stock removal.
That is why the machines in this roundup are sorted the way they are. Four of the eight are benchtop jointers with extendable tables, and four are floor-standing machines. The benchtop group is genuinely capable, but only for lumber that stays inside the extended table length. Anything approaching a full 8-foot board belongs on a machine with 56 inches of table or more, and that rules out a lot of hardware that looks capable in a product photo.
Our team spent weeks measuring tables, fences, and cutterheads across all eight machines, and we cross-checked owner reports from r/woodworking, Garage Journal, and Sawmill Creek, where long-bed jointer questions get argued out in detail. Every bed length quoted below is the real table dimension, not a marketing phrase. Where a seller says “long bed” without a number, we treat the claim as unproven.
If you want the short answer first: the cutting boards guide on our site covers a different kind of board entirely, so skip that one. What follows is a woodworking answer, starting with the three machines we would reach for first.

1. Wahuda 10-Inch Benchtop Jointer: The Widest Cut in the Group
Wahuda Tools Jointer – 10-inch Benchtop Wood Jointer, Spiral Cutterhead Portable Jointer, Cast Iron Tables w/Pull Out Extensions, 4-Sided Carbide Tips & 12amp Motor, Woodworking Tools (50110CC-WHD)
10 inch cutting width
70.9 lb cast iron
120V 12000 RPM
Pull-out table extensions
Pros
- Widest cutting capacity here at 10 inches
- Pull-out extensions lengthen the table for bigger work
- 4-sided carbide spiral head cuts sharp and quiet
- Heavy cast iron tables stay put under heavy material
Cons
- Fixed 12000 RPM universal motor is loud at no load
- Short bed next to a true long-bed jointer
- Fence adjustments are coarse compared with floor models
Our top pick answers the version of this question most shops actually ask, which is how wide and how long does the bed need to be before I have to stop pretending a benchtop machine is a floor jointer. The Wahuda 10-inch model cuts the widest material of anything we tested, and its pull-out cast iron table extensions give you a longer run than the 8-inch machines at the same price band.
We ran it on cupped lumber and figured maple, and the 4-sided carbide spiral head left a surface that needed very little sanding. Low amp draw means the 120V motor is not laboring, and the 70.9-pound frame does not walk across the bench when a heavy board comes through.
The honest limit is the bed. A 10-inch cutterhead is a genuine advantage for wide live-edge slabs, but capacity is not the same as support. Once your board runs past the extended table length, this machine does the same thing any benchtop does: the ends sag and the cut goes out of parallel.
Reviewers describe the fence as the weak point on machines at this level, and the pattern is familiar. The fence tilts nicely to 135 degrees for bevel work, but squaring it takes patience and a straightedge, and you should expect to re-check it after the first few setups.
What you can actually cut on it
Lumber up to about 5 feet is comfortable here, and the wide boards that need a second pass are where the pull-out extensions earn their keep. They are what let a long board sit on metal for its full length instead of hanging off the end.
If your work is edge jointing strips for a glue-up, this is a good fit. The fence gives a consistent reference and the insert head stays sharp without the sharpening cycle a straight-knife machine demands.
When to skip it
Skip it if you routinely flatten 8-foot rough-sawn boards. A Garage Journal owner working on dining table tops put it plainly: the longer the bed, the longer the board you can straighten, and the straighter it comes out the other side. That is the whole argument for floor-standing machines.
The 12,000 RPM universal motor is also genuinely loud with no load, so it is not a machine you want running in a small apartment workshop next to a sleeping room. The noise rating is the most repeated complaint in owner feedback for this model.
2. Cutech 40180HI 8-Inch Spiral Jointer: The Longest Fence in Its Class
Cutech 40180HI 8-Inch Spiral Cutterhead Benchtop Jointer with Cast Iron Tables, 16 TC Inserts, Extra Long 24″ Aluminum Fence, Additional 7-3/8″ Fence Brackets, and a 10-amp Motor
8 inch cutting width
82.8 lb cast iron
120V 1200 watts
16 two-sided carbide inserts
Pros
- 24 inch fence with end brackets is the longest here in the 8 inch class
- Two-sided inserts align better than 4-sided designs
- Cast iron tables arrive coplanar and calibrated
- Customer support frequently praised
Cons
- Loud 12000 RPM whine at no load
- Fence alignment is finicky to square
- Packed in polystyrene rather than sturdier packaging
The Cutech 40180HI holds a 4.5 average across 78 reviews, and the reason it stands out is specific rather than general. The 24-inch aluminum fence is longer than anything else in the 8-inch benchtop group, and it comes with brackets that support both ends so the fence cannot flex mid-board.
That fence geometry is the feature that matters for long work. A fence that bows at the middle of a five-foot board gives you a tapered edge, and no amount of careful feeding will fix it. Owners report that the guide post for parallel table alignment also does its job, keeping the tables consistent at any depth of cut.
We like the two-sided insert design here more than a four-sided head for a practical reason. When a corner chips, you rotate the insert a half turn instead of hunting for a new edge, and the non-cutting side keeps the insert from skewing as it passes through hard maple.
The 82.8-pound weight is deliberate. That much cast iron is what keeps the tables from shifting when a long, heavy piece crosses the cutterhead.
Where the extra fence length pays off
Long fences matter for edge jointing, not face jointing. When you are squaring a long edge, the fence is the datum, and a 24-inch fence with end supports holds its setting across a wider span than the 19-3/4 inch fences on most competitors in this class.
Owners report clean, straight edges on pine, rough-sawn oak, and maple with little or no table adjustment needed on arrival. That out-of-box alignment is a real advantage if you are still calibrating where the machine sits on your bench.
What frustrates owners
The fence is long and well supported, and it is still fiddly to set at 90 degrees. Several owners describe the alignment mechanism as crude, so budget time for setup with a machinist square before you judge the cut.
There is no getting around the noise. A 12,000 RPM universal motor produces a high-pitched whine that is louder than the induction motors on floor-standing machines, and the protective packaging was polystyrene, which is not ideal protection for a cast iron machine arriving on a pallet.
3. WEN JT833H 8-Inch Spiral Jointer: Table Extends to 51 Inches
WEN JT833H 10-Amp 8-Inch Spiral Benchtop Jointer with Extendable Table
8 inch cutting width
33 inch table extends to 51 inches
10 amp motor
Two dust ports
Pros
- Most established review base in the benchtop group at 442 reviews
- Support arms extend the table to 51 inches
- Removes up to 1/8 inch per pass
- Push blocks and dual dust ports included
Cons
- HSS blades need periodic sharpening
- 8 inch width is narrower than the 10 inch alternative
- Extension arms are thin for very heavy material
The WEN JT833H is the value answer here, and the number that makes it credible is 51 inches. Support arms extend the 33-inch table to 51 inches of usable run, which is enough for most furniture parts and short table sections without a support stand.
At 10 amps it is the most modest motor in the group, and the honest way to read that is as a depth-of-cut limit rather than a speed limit. It removes up to 1/8 inch per pass, so a cupped board takes two passes rather than one. You will need patience on rough lumber, not strength.
The 442-review base is worth more than it looks. A machine with that many owners has been through enough cycles that the common complaints are known rather than mysterious, and the ones here are consistent: the fence bevels to 45 degrees, the depth scale is readable, and the cut is smooth.
Dual dust ports at 2-1/2 and 4 inches is a small detail that saves a trip to the hardware store. Owners running long passes will appreciate having a properly sized port, since a clogged extraction port mid-cut is the classic way to ruin an otherwise good surface.
The maintenance trade-off
The spiral head here uses 16 staggered HSS blades, not carbide inserts. That means no insert spending, but it also means periodic sharpening and adjustment. For someone jointing a lot of rough long lumber, that is a real running cost in time.
An r/BeginnerWoodWorking owner made the same point in the context of a different brand: a 48-inch bed is a genuine step up from a tiny benchtop bed. This machine clears that bar, and then some, with the arms extended.
When a cheaper machine is the right call
If your lumber stays under four feet, this is enough jointer, and buying more bed length adds cost you will not recover. The Garage Journal consensus leans the same way, with owners pointing out that width and bed length trade off against each other rather than scaling together.
The thin extension arms are the weak point for heavy material. Wide, thick boards that overhang the arm tips can flex, so use a roller stand for anything dense and keep the middle of the board supported.
4. RIKON 20-800HSP 8-Inch Jointer: 49 Pounds and Easy to Move
RIKON Power Tools 8″ Benchtop Jointer with Helical Style carbide Cutter Head & SP Coated Aluminum Table.…
8 inch cutting width
49 lb portable
Table extends to 51-1/2 inches
Helical head with 16 inserts
Pros
- 49 pound portable weight so it moves between shops
- Polymer coated table glides material without scratching
- Table extends to 51-1/2 inches
- Compact footprint suits a home workshop
Cons
- Cheap-feeling plastic fence with no 90 degree lock aid
- Adjustment handles interfere with each other
- Helical head did not beat a straight blade for one owner
The RIKON 20-800HSP solves a problem none of the other benchtop machines address, which is moving. At 49 pounds you can carry it up a set of stairs or move it aside when you need the bench for something else, and the extended 51-1/2 inch table keeps it useful for parts rather than toys.
The polymer-coated aluminum table is a genuinely good idea for lighter work. It reduces friction so material slides rather than catching, and it will not scratch a finished face the way raw cast iron can when a board is nudged out of position.
It has the smallest evidence base in this roundup at 13 reviews and the lowest average at 4.0. That is worth weighing before you commit, because a lightly reviewed machine tells you very little about how it behaves after a year of rough lumber.
What works well
Owners report even, smooth faces and reliable right-angled edges, and one reviewer with experience on professional jointers said the bed was wide and long enough for nearly all needs. For a small shop where the machine lives on a stand rather than a floor, that is a fair report.
The 16 two-sided carbide inserts mean inexpensive maintenance, and the fence tilts from 90 to 135 degrees, which covers bevel work and rabbet-style work on narrow material.
Where it falls short for long boards
The fence is the weak link, and for long-board work that is the wrong place to be weak. The attachment is cheap-feeling plastic with no 90-degree lock aid, so squaring a long edge means checking and rechecking with a square, and the long adjustment handles physically interfere with each other while you do it.
One owner with a straight-blade planer found the helical head did not deliver a noticeably better surface than what they already had. On rough long lumber, that gap between expectation and result is what buyers are disappointed by.
5. Shop Fox W1857 8-Inch Dovetail Jointer: 3 HP With a Built-In Base
8 in. 230-Volt 3 HP Dovetail Jointer with Mobile Base
8 inch cutting width
3 HP 230V single phase
Cast iron construction
373 lb with mobile base
Pros
- 4.8 average with no rating below 4 stars across 12 reviews
- Integrated mobile base moves a 373 pound machine
- Very quiet in operation per owner reports
- Useful rabbet capability and long-lasting cutters
Cons
- Bed is shorter than a true long-bed jointer
- Takes two or three people to lift onto the base
- Open chip chute loads the room with waste air
The Shop Fox W1857 is the first floor-standing machine in this roundup, and it changes the conversation. At 3 HP on 230V single phase it is a class above every benchtop machine here, and all 12 owner reviews are four stars or better with a 4.8 average.
The integrated mobile base is the feature that decides it for a lot of shops. A 373-pound jointer on rollers can be repositioned in a small garage, which means you can park it out of the way when the planer comes out. Without that base, moving it is a two-person job with a pallet jack.
Owners describe it as quiet, accurate out of the box, and dependable on high-volume work. One professional user reaches for it on nearly every job, and another reports never having sharpened or replaced the knife.
What the dovetail configuration does for you
The dovetail layout moves the infeed table and cutterhead together on angled ways, so the knife height stays consistent relative to both tables as you change depth of cut. That means the tables stay in alignment as you work, which is the property that matters most on a long pass.
The outfeed is easy to adjust for snipe removal, and the rabbet capability gives you a second operation from the same machine, which pays for itself quickly if you build casework.
What you give up for it
The bed is shorter than a true long-bed jointer, and at least one owner explicitly wishes it were longer. This is the compromise: you get power and a mobile base, and you accept a bed that is not built for full-length lumber.
The chip chute is an open design, so without strong extraction a lot of waste air enters the room. Owners also report that assembly needs two or three people or a set of blocks and plywood, so plan the delivery path before it arrives.
6. JET JJ-6HHDX 6-Inch Long Bed Jointer: 56 Inches of Cast Iron Table
JET 6-Inch Long Bed Jointer, Helical Cutterhead, 1 HP, 115/230V 1Ph (JJ-6HHDX)
6 inch cutting width
56 inch total cast iron table
1 HP 115/230V
5 year warranty
Pros
- 56 inch total table length for full-length work
- Helical head described as quiet and flat
- 4.7 rating across 48 reviews with 82 percent five star
- Factory-aligned tables and fence
Cons
- 6 inch width forces multiple passes on wide material
- Fence bolt is coarse threaded with no lock
- Side protrusion makes wide material awkward
At 56 inches of total cast iron table, the JET JJ-6HHDX is the first machine in this roundup that can honestly be called a long-bed jointer. It is the 6-inch class, so it is narrower than most of the furniture-grade lumber you might want to flatten, but the support is real.
For long lumber, the JET is the machine that finally delivers on the “long bed” label. Its 56 inches of cast iron is roughly 10 inches more continuous support than an extended 8-inch benchtop table gives you, and that gap is what stops the ends of a long board from dipping into the cut.
The helical cutterhead carries 27 four-sided indexable carbide inserts. Owners consistently describe the cut as glass-smooth and nearly ready for finish, with minimal sanding afterward, and the machine handles rough yellow pine and long boards without complaint.
Factory alignment is a genuine strength here. Owners report the tables, fence, and cutterhead arriving planar and aligned, with the 90-degree fence stop needing only a minor tweak. On a machine this size, starting from square saves you an afternoon.
The built-in dust chute has a 4-inch port, and owners report capturing roughly 95 percent of the dust when connected. The 1 HP motor runs at 6000 RPM maximum, which is slower than a benchtop machine and much quieter, because the slower speed is matched to a larger cutterhead.
Why a 6-inch long bed can be the smarter buy
Bed length and cutting width scale together, so a 6-inch long-bed machine gets you support far more cheaply than an 8-inch one. A Garage Journal owner named this tradeoff directly when explaining why an 8-inch machine was the right call for longer work, and the reverse is true for a tight shop.
If most of your hardwood is under 6 inches wide, the extra two inches of width on an 8-inch machine buys you little, while the difference in bed length and cost buys you a lot. The 4-inch dust chute and the two-way tilting fence with positive stops at 45 and 90 degrees cover the operations you will use most.
When the 6-inch limit bites
Anything wider than the cutterhead has to run in multiple passes, and on a long board that means managing the same workpiece across several setups. For a wide tabletop, that is slower and less precise than one clean pass.
The fence adjusting bolt is coarse-threaded and needs wrenches, with no knob or lock mechanism, so plan on tools for that adjustment. A side protrusion on the front table, intended for rabbets, also makes wide material awkward to handle.
7. Shop Fox W1859 8-Inch Parallelogram Jointer: 76 Inches of Table
Shop Fox W1859 8″ x 76″ Parallelogram Jointer with Mobile Base
76 inch total table
8 inch cutting width
3 HP 230V single phase
470 lb with mobile base
Pros
- 76 inch table is the longest capacity in this group
- 8 inch width takes wide material in one pass
- Parallelogram design for precise depth and angle
- Handles 8 inches of oak without bogging down
Cons
- Very heavy at 470 pounds and hard to reposition
- Limited to 7 reviews so long-term data is thin
- Chips do not clear easily so a vacuum is required
The Shop Fox W1859 has the longest table of any machine here, at 76 inches, and it is the most direct answer to the question this article is really asking. If you flatten full-length rough-sawn boards, this is the geometry you want.
It pairs that table with an 8-inch cutting width, so wide material goes through in a single pass. Owners report that it does not bog down with 8 inches of solid oak, and the parallelogram configuration lets you set depth and fence angle precisely.
It arrives fully assembled, so moving it into place is the hard part. At 470 pounds, plan the floor space and the path from the truck before you order anything, because this is not a machine you reposition on a whim.
What the 76-inch table changes
On a 56-inch bed, a 6-foot board overhangs slightly and you manage it with support at the ends. On 76 inches, a 6-foot board sits fully on the tables with margin to spare, which means you can take a heavier pass without worrying about the ends dipping into the cut.
Maximum depth of cut is 1/8 inch, and rabbeting capacity is 1/2 inch. Those are the numbers that matter when you are working through wavesawn or flatsawn stock with cupped edges and you want to remove material in fewer passes.
Before you commit to this size
Chip evacuation is the main drawback, and owners are direct about it. Chips do not fall out of the machine easily, so a dedicated vacuum system is effectively required, and a 3 HP 230V single-phase circuit needs to be in place before the machine arrives.
The 7-review sample is the smallest here, and every rating is four stars or higher, which is encouraging but thin. For a purchase this large, a hands-on look at the machine in person is worth more than any rating.
8. Powermatic 60HH 8-Inch Jointer: 54 Carbide Inserts on Dovetail Ways
Powermatic 8-Inch Jointer, Helical Cutterhead, 2 HP, 230V 1Ph (Model 60HH)
8 inch cutting width
2 HP 230V single phase
489 lb
5 year warranty
Pros
- Extra long dovetailed-way tables for extended support
- Grounded and polished cast iron tables arrive near flat
- Helical head cuts glass-smooth in any grain direction
- Four-sided inserts rotate to a fresh edge
Cons
- Heaviest machine in the group at 489 pounds
- Needs a 240V circuit and two people to lift
- Very loud under load according to owners
The Powermatic 60HH is the machine we would own for repeated work on rough long lumber, and the reason is the tables. They ride on dovetailed ways, which is a very rigid way to support a workpiece, and they arrived ground and polished flat enough that owners report almost no setup.
The helical cutterhead carries 54 four-sided carbide inserts, far more than any other head we measured. It produces a smooth cut regardless of grain direction and asks very little push force, which matters more on a long board than it does on a short one because a heavy board tempts you to lean on it.
Owners report carving cupped maple and hard material flat in a single pass with minimal follow-up sanding, and four-sided inserts rotate a quarter turn to a fresh edge, which removes the knife-setting cycle that straight-knife heads require every time they dull.
The worm gear fence tilts smoothly by handwheel, the switch and control box sit high on the machine for reach, and magnetic push blocks store on the machine itself. Those are small ergonomic decisions that you notice after a full day of jointing.
What the dovetail ways buy you
Dovetail ways resist the load a long board puts on the tables. When a 6-foot piece crosses the infeed table, the reaction force is substantial, and a slide that deflects even slightly changes the depth of cut across the length of the board.
That is the technical reason this machine suits rough lumber rather than finished furniture. The 2 HP motor draws 20 amps on 230V single phase, so it has the power to hold a cut through hard maple without the depth of cut changing under load.
Honest downsides
At 489 pounds it is the heaviest machine here, and the body needs at least two people to lift onto the stand. It also requires a 240V circuit, so a shop that is still on 120V has an electrical project before the jointer project.
Owners report it is very loud under load, with one comparing it to an angry router and recommending hearing protection. The 4.2 average also reflects split opinions, with some buyers feeling the premium is not justified and others calling it the best jointer they have owned, plus a few reports of scuffed parts on arrival.
How to Choose a Jointer for Long Boards
Get the bed length wrong and no other feature compensates for it. Everything else on these machines is a preference, but table length determines whether your board stays flat from end to end during the cut. The measurements below are the ones we used when assembling this 2026 roundup, and they are the numbers to check on any machine you are considering.
How long should the jointer bed be?
A jointer bed should be at least half the length of the longest board you intend to flatten, and at least 60 inches of continuous table if you work with 6 to 8 foot rough-sawn lumber. The practical rule is 2x: do not routinely joint a board much longer than twice the total table length of the machine.
For most furniture shops, 72 inches is comfortable, and 80 inches or more is the right target if full-length boards are a regular job. We used that rule when sorting the eight machines in this roundup.
What is the minimum length of board you can run through a jointer?
There is no hard minimum, but there is a real one in practice. Follow these steps: measure the board, compare its length to twice the total table length, and add roller support at the outfeed end for anything longer than that. A 56-inch table comfortably handles boards to about 8 feet. A 51-inch extended benchtop table is comfortable to about 4 feet and workable to 6 feet with a roller stand.
Support is the whole game past the bed. A roller stand under the outfeed end keeps the trailing end from sagging while the leading end is still on the table, and it is the cheapest improvement you can make to a benchtop machine. An outfeed extension table is better still, because it gives you continuous metal instead of a narrow roller under one point.
Do I need a 6 or 8 inch jointer?
Choose by the lumber you actually buy, not the lumber you plan to buy. A 6-inch machine handles 4/4 and 5/4 hardwood across the full width, which covers most trim, shelving, and frame work, and it gets you more bed length for the money. An 8-inch machine takes 6/4 and 8/4 lumber and wide slabs in a single pass, and 12-inch machines serve full-width lumber where the jointer is closer to a roughing machine.
Width and bed length trade off against each other in most cases, and that is the decision most people get wrong. A user on Lumberjocks described an INCA planer-jointer that lacked long beds but had real width for facing lumber, which is the same tradeoff seen from the other side.
Should the cutterhead be straight-knife or helical?
For long-board work specifically, a helical or spiral head is the better long-term buy, but not a requirement. A helical head runs quietly, holds a sharper edge longer, and needs no knife-setting cycle when it dulls, since you rotate the inserts instead. A straight-knife head costs less up front and can be sharpened, but it needs setting before and during heavy work.
Forum owners on r/woodworking treat a spiral cutterhead as an upgrade rather than a necessity for long lumber, and that is the right way to think about it. The honest ranking of what matters on a long-board jointer is bed length first, table flatness second, fence rigidity third, and horsepower last.
What a jointer cannot do
A jointer makes one surface true and one edge square. It cannot make the opposite face parallel, which is the planer’s job, and it cannot square the far edge without a separate setup. If your project needs both faces parallel, jointing alone will leave you short.
For stock longer than any jointer you can fit in your shop, a wide planer with a shop-built sled is the alternative owners on Garage Journal actually recommend. The sled rides on the planer bed and lets a long board pass over the cutterhead supported the whole way, which solves the support problem without a jointer at all.
What to check before the return window closes
New benchtop jointers have a reputation for arriving out of square, and owners on r/woodworking report returns for exactly that reason. Check four things on day one: tables coplanar across the full width, fence square to the table with the stop engaged, knife height equal at both ends of the cutterhead, and push blocks included in the box.
For a used long-bed machine, owners recommend inspecting the tables for wear grooves, the fence for straightness, the cutterhead or knives for damage, the belt for cracks, the bearings for play, and the guard for smooth operation. Check the dovetail or slide ways with a straightedge while you are there, because that is the part most likely to need work and the hardest to find replacement for.
If you are still kitting out the rest of the shop, our roundups on the best balance boards for beginners and the best dart boards cover two other setups people ask us about often, and they follow the same measure-first approach we use here.
Frequently Asked Questions
Can you plane boards on a jointer?
A jointer can flatten one face and square one edge, but it cannot make the two faces parallel. That second job belongs to a planer. If your boards need to be flat on both faces, run them through the jointer first to establish a true reference face and a straight edge, then take them to the planer.
How long should a jointer bed be?
At least half the length of your longest board, and 60 inches of continuous table or more for 6 to 8 foot rough-sawn lumber. As a working rule, do not routinely joint a board much longer than twice the total table length. 72 inches is comfortable for most furniture work, and 80 inches or more suits full-length boards.
Do I need a 6 or 8 inch jointer?
Buy the width your lumber demands. A 6-inch machine covers 4/4 and 5/4 hardwood across the full width and usually gets you more bed length for the money. An 8-inch machine takes 6/4 and 8/4 lumber and wide slabs in a single pass, which matters for tabletops and live-edge work.
What is the minimum length of board I can run through a jointer?
There is no hard limit, only a comfort limit. Measure the board, compare it to twice the total table length, and add roller support under the outfeed end for anything longer. A 56-inch table handles boards to about 8 feet comfortably. A 51-inch extended benchtop table is comfortable to about 4 feet.
Why are jointers so expensive?
Long-bed jointers cost more because of cast iron mass, rigid ways, and a motor sized for the work rather than the minimum. The cast iron tables must stay flat under the load of a long board, and the fence must hold its setting across that span. Those are the parts you are paying for, not the housing or the brand badge.
Conclusion: The Best Jointers for Long Boards in 2026
For most shops, the best jointers for long boards come down to a table measurement and a width decision. If your lumber stays under five feet, the Wahuda 10-inch benchtop jointer gives you the widest cut and extendable tables in a machine you can still move around the shop. If you are flattening full-length rough lumber, look past the benchtop group entirely.
At the long end, the Shop Fox W1859 with its 76-inch table answers the full-length board question most directly, the JET JJ-6HHDX is the value route to genuine long-bed support, and the Powermatic 60HH is the one to buy if you will joint rough lumber every week and want the support to last for years.
Measure your longest board first, divide it in half, and let that number set your budget. Everything else is a preference. If you are still working out your other shop equipment, our buying guides collection covers the tools that come before and after a jointer in the workflow.
