I recently started using Delrin to make stamps.
Arbor Press purchased locally at Harbor Freight and modified at a local machine shop. On sale with coupon —- $38. Modifications cost $40.
Samples of impressions. Stamps are either .5 or one inch in width. There is lots of experimentation when making a Delrin stamp. Some of the stamps were great after engraving and others were very bad.
I had the most success with Delrin stamps that were only 1/2 an inch in width. The GF did a phenomenal job engraving and cutting the smaller stamps compared to the larger stamps. The stamps in the pictures are just a small amount of what was made with the GF.
The red X’s represent a bad engraving and the green circles represent a bad stamping with the Arbor Press.
Cutting and engraving Delrin with your GF creates a MASSIVE amount of dust inside your machine. After every engraving project—- I turned off the machine, made sure it was unplugged and used a plastic vacuum cleaner brush accessory to clean my machine. I also vacuumed the circuit board on the left side of the GF.
I can not give you engrave/cutting settings because this post would have to be placed in Beyond the manual. I did find settings with another GF community post.
