Topic tags/keywords: jig question leigh dovetail pin tail problem

I hope I can describe this clearly. I have a bit of experience with my jig (D3 Suped up to D4 w/ shelf vacum attachment) and I am making trunk. I moved to a larger than “drawer size” dovetail and layout scheme.

Yesterday, as instructed, I layed out my pins first, and then cut the tails on both ends of a board. Although the tails were of different size from each other, when looking at them against the fingers template, the dimension of each tail was flush and uniform with the edge of each finger above it. Life was good.

I then flipped the template to cut the pins. Pin cutting went well, except when I attached the two sides to the board with tails cut in each end, I could see I had a pin space problem. That is most pins and tails fit nice and snug, except two of the pins on each board were too narrow creating a gap of as much as 1/8” of space between the wall of the tail and the pin. The problem showed up on both boards at the same two locations. This lead me to think I had a layout problem, so I put the tail board back in to check and yes the tails were cut nice and flush. If I had a pin problem should I not also have an unbalanced tail? (No wise cracks). Is it a finger spacing issue or template “move back and fourth” problem? If it was a matter of moving back and fourth then would not all pins have been consistenly mis-sized?

Any thoughts or suggestions would be much appreciated.

I have a D4 I just bought used and got the bits and guides from MLCS and Rockler, but haven’t used it yet. So I have no hands on experience, but, in the videos at Leigh’s website it appears that the pins should follow the tails as long as you don’t move them when flipping the jig over.

Try cutting another test piece.
It sounds as if you flipped the boards side to side as well as the jig,
Without pictures it’s really hard to speculate.

Bob#2,

I think you’re right, that without pictures this is hard to imagine. I will do my best to get photos in the next couple of days. Please keep an eye out for them.
