Log Tenon Jig for Router Table

This is a log tenon jig I made for my router table based on seeing the product “LOGMANX”. With the pinnacle router lift I can adjust the diameter of the tenon perfectly for any fostner bit I’m using…

First attempt went better then I hoped. Just have to put an adjustable stop somewhere near the threaded rod to adjust the depth of the tenon. It will take up to a 5.5” log with any size tenon. The only downfall I have is that the router bit is around 11” from the leading edge of the table so doing odd curved logs is out of the question, it would hit the table top. Basically have to work with somewhat straight logs for the time being.

Basically my idea is if I can make it out of wood for pennies why buy it…This whole project cost me $2.19 for the 2” threaded coupler that’s mounted in the MDF. Everything else was scrap and the grinding of the threaded rod was done by a buddy of mine at his metal shop over a few beers….

Will post some new furniture hopefully soon!!!!!

Wish I would have seen this sooner!!!! I just ordered one of those LOGMANX. I also thought about making my own but decided to order the other one and hopefully tweak it to my liking. Great job!

scrapstotresures you should be happy with what you purchased. It makes a perfect tenon everytime. Found a company called MLCS Woodworking that I purchased the same size bit for $25.00 with free shipping. The bit is working out fine so far.

Have your say...
