erikbojerik Posted August 20, 2006 Report Share Posted August 20, 2006 A few days ago I took a billet of nice dry walnut and cut myself some back plates for acoustics, keeping track of the starting thickness and the final yield. If any of you guys have done this before, I'd like to compare my numbers and see how I'm doing, and if there's anything in my setup that I could tweek to improve the yield. Starting billet: 1.45" thick, 8-1/2" wide, 22" long bandsaw blade width: 0.035" (1" wide 2 TPI hook-tooth) blade tooth width: 0.050" kerf width: 0.060: My sequence was this, starting with a planed billet: 1) Cut the plate off with a 0.125" gap between fence and blade edge (too optimistic, I know...now...) 2) Remove the saw marks on the plate (thickness sander) 3) Remove saw marks on the billet (thickness planer) -repeat I managed to get 3 sets of backs (0.103", 0.091" and 0.085") and one thin plate (0.070") for headstock laminates, so 6 cuts on the bandsaw. They are on the thin side, but OK maybe I'll make a classical or two. So my yield breaks down like this: Finished pieces: 0.628" (43%) Kerf waste: 0.360" (25%) Finishing waste: 0.462" (32%) For each cut, waste from saw kerf (0.060") plus finishing (0.077") is 0.137" per cut. How does this spec out compared to your numbers? Quote Link to comment Share on other sites More sharing options...
