I got the machine wax scraps out and melted a lot of it. It's really easy to melt and pour. I had trouble with the micro-crystalline wax, I got it too hot and need to do as Rasper said and set up a double boiler. Frank told me to scrape off the dirt and bad wax, that is working great. Most comes off easily and if there is some tough stuff, I hit it with the torch and then I can cut off the bad stuff. I like working with wax and hope this comes together. It doesn't look like we will be selling our house this year, so I decided to work on this project before it gets cold.
The wax cuts really nice on the CNC, I just smoothed it down from cutting it with the band saw. The band saw didn't work real well but it cut and melted some slabs off. I think I need a coarser blade and slow it down some.
What kind of speed should I use on the CNC to cut the patterns? I tried a few different speed on the router and it din't make much difference. The travel speed was too fast so it pushed to piece and didn't cut well.
These are the shapes I poured and then the pieces I machined down. It's messy, I wish I had a small shop vac that I could only use for wax.
