Project Information

I am working on a blanket chest and want to use box or finger joint construction for the chest. After watching 15 or 20 YouTube videos on the the subject of finger joint jigs, most of them just are just variations of each other. I found one that was very different, it was more like a dove tail jig. The video was from Woodsmith demonstrating their finger joint jig, trying to sell their plans. I like that it used keys to size the fingers, you can use different size keys, and even different size keys on the same board.

The last picture was my first attempt at finger joints with scrap with no adjustments.

It seems like a good idea but your test cut was not very accurate.

One problem that occurs with template guided router finger joints is getting the guide on the router base plate centered and also making the cuts with the router oriented to the work in the same position for each cut. If the guide is off center on the router and you change the orientation of the router with each cut the width and distance of the fingers will not be consistent. I have the top end Leigh jig and even with that I have to be careful of this; especially on long box ends like a toy or blanket chest.

Thank you for the comments.

My test cut was the first cut without any kind of adjustments, not that there is much to adjust on this design. Maybe that is why you don't see many of these style of DIY jigs on the Internet. I am going to go back and check the width of each key with a caliper and adjust as necessary. I also will to another test run with wider scraps.

I am using a flush trim router bit, so the relation of the base to the center of the bit does not influence the cut.

I forgot to add slots on the fence for a clamp. I had sketched them in my rough drawing but forgot to add them in.
