Not yet started on the car wheels as they are a bit bigger in section so need more cutting but be very afraid as I will be getting a battery powered angle grinder. Regarding the temperature, that is what Ithought but I also need to increase the depth I bury the foam patterns so I can get greater pressuer and help force the molten metal through the foam.
Latest development has been to produce foam patterns with curly spokes which has taken me back to why I started metal casting in the first place and why I had to build a CNC router with which to make the foam patterns.
My world seems to go round and round in circles, but then that is what wheels are supposed to do.
John.
