Hey folks, just an update for those following:
The problem of the wax sticking to the stamp may have a simple solution. The wax seems to want metal, so I placed a bit of aluminum duct tape over the stamp and smoothed it down into the concave engraved area, using a toothpick. Then I smoothed the nonstamping surface with a Teflon bone folder.
So, what worked best for me in using the stamp was:
- Melt wax onto your surface.
- Wait 5 seconds for it to cool a tiny bit.
- Place stamp on wax, pressing gently down but not too far. Let it sit there.
- Wait about 15 seconds for wax to cool, then pull off the stamp. No sticking!
And by the way, I made this out of acrylic, not Delrin. Stuck the finished stamp onto a circular Chinese domino-like tile with 2-sided Gorilla tape.
