Recently I posted a video covering common woodworking joinery ( ) with the help of a few friends. In that video I talked to you all about making finger joints on the table saw and showed you a finger joint jig in the process. Well as I promised, here is the complete build process of that Jig.

I can’t believe no one has commented to this point. Those are nice jigs and you did a great job with the videos. Your build was very simple and straight forward and anyone should be able to make one with your instructions.

Question/comment: Your test joints appeared to have tiny gaps around the pins. Do you cut your box joints this way or would you tighten them up if this were a real project?

Thanks for the hard work you put into your videos. This finger joint jig is no exception. Great little jig. I will be building one tomorrow. Take care and be safe. Gary

Thanks guys Gfadvm what you are seeing is the pins protruding and the shadow lines from the lighting. when setting the blade height it was a little high. The joint itself was tight.

Great job.
I went the ibox route, but I’m sure this is just as accurate.

Wow… I loved your videos, GREAT JOB. And I plan to build one this weekend. Your video was informative and well thought out and your right you did it in baby steps so there is no question about how to proceed. I really learned. But I am a pain in the ass and have some questions… I would not bother writing if I did not want your opinion. I do have two issues with your jig and I want your clarification if you do not mind.
1st. I was going to build a screw advance box joint jig with clamp but I like your design better. But I would want really tight joints. GFADVM noticed in the first comment the space around your pins. As I look at the close up, I am not sure if there is space or if its an optical illusion. Could you let us know which it is. If it is space do you feel that is a product of your dado stack not being EXACTLY 1/4 or the space between your cut and the 1/4” pin and dado cut being off slightly? If its not really space around the pins, forgive the question.
2nd. The micro adjuster… I am confused on how this works. I can get your ability to, first loosen the back nuts and then push the outer face plate away from the end cap by backing the screw out and putting pressure on the end cap to move it away from the end cap. But would it not be better to drill a 3/16s hole an inch or so in, and then chisel out a home for and glue in a 1/8s nut. Also glue a second nut to the outer face of the end cap. Then use a 1/8th bolt as your adjuster so you can pull it to or push it away from the end cap or am I over thinking this…? Also a router hole for your two main bolts with 3/16ths play versus your “back and forth angling of the drill” might make it slide easier…. just a thought. I love the design, the appearance, and I WANT ONE BAD! Thank you so much for your great video and please forgive me if I am being a nudge.. just want your clarification before I begin my build. Thanks again

xraydav Question 1 look at my previous comment above…the joints were tight, what you were seeing is the pins prodruding and the shadow from the light, no gaps… also the micro adjuster.. I have since made an improvement to that and need to put out a follow up video to explain what I did.. however a threaded insert as you talked about would work as well…. I should get the follow up video out this week. .. I hope that helps answer your questions.
