Made a test mould on my home made CNC today. I broke two end mills before I found one that sort of did what it was supposed to. It is a bit rough, but seems like an ok start. The picture doesn’t really do it justice, as it looks worse in the picture than it really is. Honestly 🙂
The aluminium is from a round bar, cut with a saw and flattened using my lathe. Next step is to try this mould on the plastic injection tool.
