I had been told that Associated Lumber (the place nearby where I bought my wood) would cut down large plywood panels for customers. They had a vertically mounted circular saw on a rack, like many places that sell lumber. So I decided to do this, having them cut the 8' x 4' board into strips, then small pieces of about 9"x 12". As he finished, the lumber employee mentioned that they usually just do one or two cuts, not this many. So that was the first and last time they cut up the plywood for me, but for once it was easy to carry my wood back to the studio and I had enough panels to last me more than two months.
