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.
