I’m in the process of building a dresser and have to joint boards larger then my 6” jointer. I seen the plans for this jig in Fine Woodworking #175 by Keith Rust.

I slightly altered his plans.
- I used 3/4” BB plywood strips in between to stiffen the jig.
- I also put two dowels behind each leveling piece to help it from shifting.

Tested out the jig and it worked great. One tip if anyone decides to make this is to ensure there is a supporting leveler under the front edge. Possibility of it bouncing when entering the compression roller.

I made one of these a while back as well. Heavy but works great…. Nice work.

I found a video on the internet of Keith Rust showing how this works. That’s pretty slick. I might have to make one of these.

For those who need these a lot, the jig is a great idea, and the example here is very nicely built.

For occasional, or an on the spot need, I simply cut a strip of MDF, slightly longer and wider than the board to be planed, then add a 3-4” wide strip of MDF across the tail end of the first board. The strip can be hot glued or screwed in place, but the screws need to be well below the planing level. Put your board on, and using hot glue or carpet tape, install builder’s shims in the gaps between the carrier and bottom of the work piece. Plane away!

The carrier board also works great for accurately thicknessing or drum sanding thin stock.

I too have made and use one of these jigs, the jig works great.
However, I do use Hand tools for the final cuts.

Got one of these on my to build list as my bench top jointer is starting to be restrictive, I hope mine works as well as this one.
