I made up another Hitch Emblem for a neighboring fire department. I started out trying to use MDF for the pattern with horrible results. The letters kept breaking off while machining the pattern. To fix this, I went to plastic. I bought a .220" thick piece of Acrylic and machined the pattern out of that using a 5 degree draft cutter. After the pattern was machined out, I sandblasted the pattern at a low pressure to blend everything together and remove some of the tooling marks. This pattern has a pocket cut in the back for the hitch ring to nest into.
