Yes you can make a line on top of the board, add the shim, and make another line in order to avoid using the shim on the mating surface but the fact is you still have to stick a shim underneath the shelf which means it’s going to be harder to square up to the line. Can it be done, surely, but is more work and perhaps results in user error which wouldn’t happen if a person knew this and decided to go with a 500 from the get go.Doug S said:ChuckM said:Svar said:Just use a spacer.

Say, you use a spacer to mortise a 19mm shelf board, roughly at the center of the shelf board (8.5mm) from its edge. The DF700, however, will cut the domino on the mating side board at 15mm from the shelf board. When the shelf board is attached to the side, the shelf position won't be the same as the shelf positions you mark out on the side boards, as is the case with using the DF500.
You need to work and mark out for a thicker shelf which is actually the thickness of the shelf plus spacer if that makes any sense, then when you lay the shelf down to do a vertical plunge the spacer has given the correct offset. Hard to explain.
