Finally!! Diaphragm 5 is out of the jig.

Pete and I pulled the diaphragm out of the jig today and inspected it. Of course, I'm concerned that my method for construction will produce a good part. I found that the width of the strips I used (barely 1 1/16") should really be wider in order to allow for the inevitable slight misalignment of the layers. I used the drum sander I made for it's intended purpose (video posted), to sand the sides smooth and down to the design thickness. The sander worked great. However, when I stopped at exactly 1" thick not all of the strips were flush. There is a little unevenness in a few areas. I'm not sure this is a show stopper, but I must make a decision now on what to do. I could redo the part (about $80 down the drain). If I choose to keep it and make the next one I will destroy the jig for this one in the process. I might find that as I'm much better at doing this now, my next ones will be so much better that I will want to make another #5. If so, it will be about $40 for a sheet of particle board to make another jig that size. It's only money right? Check out the video and builder's log too.
