Matthias Wandell is a genius, and his Screw advance box joint jig is a marvel.

I made this finger joint with the jig built by his plans (I upgraded it recently).
The ruller is Metric, not Inch. every finger is 2.5mm thick ׂ(=0.09 inch)
The stock is 6mm thick, maple. came up perfect with no gaps at all in first try.
Making all the finger joints for the box took less than 2 min.

-- Only by the 4th time I realized how it was suppose to be done in the first place.

Of all the questions i get about my furniture the most frequent is “Wow how did you do this finger joint so nice and accurate?” And every time I tell the story about the x-RIM engineer that made a career out of inventing machines made from wood.

Looking forward to see what you are making!

Nice joints there Elyasaf! How long did it take you to make the jig? Maybe something I’ll look into now.

I reffer to him as leonardo de vinci of our times. if there was a nobel prize for woodworking – he should be the one.
This is the 7th(!) jig that i have built by his design and plans.
Joel – since i enter my workshop only at night, its hard to say. the first time i made the jig, it took me two weeks. it was actually my first wooden project ever, and i didn’t understand much in woodworking. also it takes time to find all the relevant accesories (ball bearing, screw threads, bolts and so on. i guess that if you have all the needed parts under your hand, you can finish it in one day of work. but, you should expect some errors that would take time to figure out. it takse some time till you are familiar enough with the jig and can fully understand its parts and how it works. i would advise that before you enter the workshop, print all the information avaliable (there is a lot), plans in full scale, dowload the series of 4 youtube videos to of how to build to your phone so you can watch them in the workshop while working, gather all the needed parts, and all the needed lumber.
Good luck!
I made a new jig a week ago, and it took me one day
