Playing around with aluminum again.
Drop down to the last four rows of pictures. I shortened the mpcnc back to my first dimensions. Have about 510 by 470mm of cutting area. After surfacing the spoil board I tried cutting some 2″ aluminum bar. Didn’t work out so well. So I attached a second piece of mdf on top of the first piece, and attached a half inch piece of plywood to that. Then I did the masking tape and superglue method of attaching the aluminum to the plywood. Much better results! End goal is to mill out some name plates for my ladders at work.
