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
