Appreicate the respsones...
All,
Thanks for the feedback! Will stay with 1/8" pan head, but will switch to steel mandrel. Still need to determine grip…Anyone know the wall thickness of the DB-1 chassis bottom square tubing?
Paper Clip Depth Gauge...

Make a very small L shaped tool, stick it in the hole, mark the depth and then measure it.
Thanks for the suggestion. Actually did just this yesterday. Made my own "depth gauge" bending a paper clip into a "L" shape. Measurement with the 0.063" pan came out to ~0.153" yielding a 0.090" wall thickness. Seemed high to me especially given how well the 0.125" grip rivet is holding the pan in place, but based on the is measurement I will go with a 1/4" grip rivet. Just curious if anyone knew for certain the wall thickness...
