Cutting 3/16 inch Aluminum Sheet
I started to cut out parts from the 3/16" 6061-T6 sheet. The simplest approach seemed to be to cut out strips and create blanks in various sizes to allow for the parts to be cut. I cut two 1" wide strips and marked a 2-1/4" wide strip. I also marked the SNX-T12-07 Forward Attach Fitting for later cutting.
