Step 3: Test Run 2
The plastic formed pretty well but it could be better. I think I need to let it sag a little more. On one side it pulled out of the frame so I'll have to put some spacers on the frame to clamp the plastic tighter. I also need to experiment with different shapes to figure out how to avoid the webbing that happened at the corners. The shop vac worked pretty well but this could be upgraded too. Overall this is a good start though. I want to make some body parts for my motorcycle and I have a few other ideas. I hope this was enough info for you to make your own vacuum forming machine and if you have any questions just post and I see if I can help out.
