I had a fun weekend building an increment box joint jig that relies on a threaded rod 16 tpi so 2 turns = 1/8. https://www.youtube.com/watch?v=JYxDXHGRRrk
I am now on a quest to buy a good 8" or 10" 1/8" blade that will prodice a good flat bottom finish but minimize tear out. .125 kerf FTG. I see there are box joint sets that do 1/4" and 3/8" but they are pricy.
Thoughts? Suggestions?
