Built this jig last year as I needed it for a project I was to build. Its a Lynn jig and I found the plans on line. It has a positive stop at one end so I know when I have made a full turn (got that idea from Ed stiles on youtube). The important part about using it is to ensure my dado blade is exactly set at 1/4” or whatever size I use. After first cut I realized I had to add .045” shims to the dado blade. Then it worked great.

Used bearings on each end of threaded rod and turns beautifully.

Very well executed.

I had seen this Plan a while back and did not ‘note it’ or save the source and since then decided to build one and haven’t been able to find the Plan again. thanks for sharing your build and including the references.
