I recently converted my mini-mill to CNC and watching it run full speed with aluminum is a little terrifying. I thought having some machinable wax to play with while I learn would save me a lot of anxiety.
After much searching on the interwebs I decided on a roughly 4:1 mixture of paraffin to LDPE. I decided to add some stearic acid and colorants so my final ratio was more like 4.5:1.
My recipe:
- 1564g paraffin
- 340g LDPE
- 47g Stearic Acid

| All ingredients ready to go |

| Molten wax and plastic slurry poured into molds. |
Milling tests are going to take some time as it’s in disarray at the moment.
