They turned out pretty good and the client was happy, but they were never perfect enough for my tastes. It's difficult to get the machined look with hand tools and almost impossible to engrave graphics which is a distinctive feature of these guns.
Step 1: Laser Cutting
The body of each gun was cut from 3 pieces of 1/4" MDF, with a gap in the middle section for a trigger and hammer, which were also cut from 1/4" MDF. I also left a gap in the middle section for a faux barrel. Raised areas like the side of the slides were cut from 1/8" MDF.
