When I am cutting thin plastics like the Romark Flexi Brass brushed (.020) material, I find that it warps and cups while I am in the middle of a vector cut. The strips are between 1.5" to 3.5" wide and 22" or so long.

My idea is to make some hold downs that would take care of maybe 80% of the movement. I would like to use 3/16 x 1 x 22" cold rolled bar stock and create a .040 rabbet for the material to slide under.

I have about 5/16" clearance now using a 1.5" focal lens.

The issue is that I will need to remove the auto focus plunger on my Epilog mini 24 to have more clearance. Also in case I need to hold down thicker material down the road using different custom hold downs.

Has anyone removed their plunger? I can see what looks like a small allen screw on the side. Is it that easy?
