At 77 I’m going to try my hand at Kumiko so I’ve been researching on YouTube and found your jig build to be simple, clever, and accurate. I just finished a small 11 inch version of it to use with my block plane. I’ve got the blocks and starter set ordered and once that gets here I should be set. My version of your little planing jig is accurate to 1 thou in 11 inches so because I’m only doing this on a small scale for my own pleasure it should be sufficient. I plan to use it for accenting small items like boxes, napkin holders, coasters, etc. the only change from your design was I used nylon 1/4 -20 bolts for the elevation adjusting sides. I got all the parts from a 4x4 Douglas fir cut off. Thanks for the good plan and the (something from nothing) fun build.
Ok so I hope you take this as the compliment that I mean it to be...You are the Mr. Rogers of woodworking videos! Love it! Not to mention a super cool jig build! Thank you for sharing!
