So I ordered a cnc router from China but I got impatient waiting so tried to make a mold the gelcoat and fibreglass way. It didn’t go so well, I could probably use it but it’s a bit warped because I used a heat gun to try get all the paint out of it and overall it’s a bit shit, now the cnc has arrived so I don’t care, I can start again and life will be easy! One issue though, how does it work? It came with no instructions or software. It does have a dsp thingy with a usb hole and internal memory so I’m thinking I just need software like vcarve pro, learn how to use it, save the code to a flash drive and I’m good to go…right?
I’m thinking if I cut the mold out of mdf, leave it on the machine, paint it with glue (pva or epoxy) the mdf will swell, then when it’s dry run the finish cut again to remove surplus glue, swelling and furry bits. Then wax the heck out of it. Will this work? I’m probably going to try it anyway but any tips would be appreciated.
