Terry, et al, It is heavy for a reason: Betters accuracy. No, it is not difficult to build. It is a box w/external adjustable legs, (made out of 2/4's. It has shelves inside the front doors that are full-extension glides. On the top is mounted a 2'x2'x2" piece of butcher block; it is hinged for incremental angles. (The major angle is obtained by adjusting the legs) The incremental angle is adjusted by carriage bolts/"t" nuts (2). I have a Delta/Rockwell Radial drill press. (Olde, but same as current model). I bought an extra mounting base and affixed it to the butcher block. I also bought one extra vertical column, which I machine cut in 3 different lengths: 6", 9" & 7 1/2" (what was left). The box is approx. 22" wide x 24" deep x 28" high. I has 4 shelves for the tuning pin storage/weight. The box has doors that swing out and have a latch, when closed, to keep it closed and contain the t.pins. the whole thing is sitting on a platform made of channel iron w/casters welded to it and a 1" thick piece of plywood that is approx. 33" x 28" overall. The box is not "mounted" on the platform, it simply sits on it. I first tried casters on the legs of the box, but the "caster" action" screwed up the depth accuracy; hence the platform. This whole contraption is infinitely adjustable for all drilling, (in the piano), applications. As I work on infinitely different pianos, I needed something that would do the job ALL the time. It works on Uprights as well as Square Grands, Grands and anything else needing portable (well?...) drilling. It also serves the dual purpose of housing all the Tuning Pins I have in stock. (Back in the 70's we had an extreme shortage of tuning pins, so I keep a good stock now!)(Dern US Steel!) But that's another story. I hope this makes the earlier posting a little clearer. If not, then use your imagination and ingenuity. Best Regards, Joe Garrett, RPT, (Oregon)
