I am sure that this has been discussed before in other posts, but I am making a box for my father in law for Chrismas and making half blind dovetails for the joints. I am using the Porter Cable jig and my dovetails are way too tight to even put together. what is the fix?

Probably the easiest thing to do would be to finish them by hand. Clamp the pin board down and use the tail board to lay out the lines. Then use a sharp chisel to approach your lines.

Usually adjusting your jig can make your joints tighter or looser ,check your manual for how to make the adjustment.

To adjust for tight or loose dovetails raise or lower the bit in the router this is critical, adjust in or out about 1/32 of an inch. keep adjusting until you have it right make. Then make a cut in a small piece and save it so the next time you can reset the same depth. The router bit depth will always be the same on that jig.
