After wasting many hours trying to sand flat my last cutting board I decided to make a planning jig for the router so I can plane large boards accurately and not invest in a larger thicknessing machine. The hardwood ply 12mm/18mm cost £20 and the planed white wood was £10 with enough left over to make an off cut shelf, so far cheaper than a 18’’ thicknesser.

I wanted to be able to move around freely with out getting caught up on clamps holding the piece in place I used some scraps as wedges to hold it firmly and put some packers in the thin areas for extra security, the cutter I chose was a 25mm dish carving cutter as I thought it would give a better finish and be more stable during use and avoid tear out on the edge and this worked well. I attached an extra piece of timber on the bottom so I can hold the whole jig still in the vice.

Once I finished my next board I couldn’t wait to check it for flatness and its perfect no rocking at all, then I measured with a calliper and it varies 0.4mm end to end which is good enough for me.

The whole jig took 1hr 30mins to make and the time this is going to save me in the future will be huge, I wish id made one years ago!

If any of you make your own design id love to see it, might be able to improve mine in the future

Yours is certainly nicer than mine.

But yeah, I’ll never make another cutting board without it.

I use stacked up 3” plywood strips for the sides of mine. A good coat of paste wax and the thing moves smooth as silk in both dimensions.

Nice solution to a typical woodworker’s most dreaded task – sanding.
I made mine for face jointing boards, and it uses the workbench top as the flat reference for the router.
A large part of the fun in woodworking is creating solutions for improving the craft.

Good simple solution. I tried to set something up a few months ago that was a complete failure but I think I will give something like this a shot soon. Thanks for sharing!

Nicely made, but why won’t you use a hand plane to flatten a cutting board. I have made a lot of cutting boards and always flatten them with a jack plane. It takes me roughly 20-30 minutes to flatten a cutting board on both sides. After you have you the hand plane there is only little sanding to be done.

Nice jig.
I made mine so that the base plate is free to move back and forth. Yours is a better solution.
