Dimpled all parts. Used 1/2" boards to make jig for DRDT2. Worked great.

Half inch press-board makes a nice table extension for dimpling.

Other builders have said that the two shims are included in their kits. I still haven't positively id'd any such thing from my kit. I fabricated from .040 sheet. Seems to work just fine.
10 hours.
