Cut a slot in one of my EAA tables to hold the home-made dimpler. I built it out of an old bed frame and used on my -6A. Loaned it out to a -7 builder, so it has two to its credit. Now it gets a -10.
Slot holds dimpler with the dimple die slightly proud of the table top. Put a sheet on the table and into the slot and then the dimpler. Simple. When it is out, the piece that was cut out goes back in so the table is just as before.
