First issue – The changer mounting blocks were designed to be bolted through from the bottom but Mr. Wilcox had cut the holes for the changers too wide and there was no wood left for the bolts. He drilled out the mounting blocks from the top and attempted to use decking screws at an angle to hold the changers in place.
The wood under the C6th changer was all busted up, so there was no hope for that neck. I was able to mount the front changer with two machine screws, thru-bolted with a large hand-made washer on one; the other actually went through a lip on the end plate. I know this is Mickey Mouse but it’s the only possibility.
Second issue – With the strings on, the all-pull changer fingers scissored all the way back because there were no stops for the raise fingers. Not only that, I had to make the return springs as there was no way to buy any the right size.
What I did – Since I was planning on only four strings being lowered, the other six strings I riveted the raise fingers and lowering fingers together. That way they act like one piece, similar to a pull- release system.
The other four, I cut some sheet metal and welded extensions to the raise fingers at the bottom so they would contact the same stop as the lower fingers. All I have is a stick welder so I did the best I could and ground out the imperfections. After a couple of attempts I finally found the right size piano wire for the return springs.
I eventually realized that I didn’t have the parts to install a reversing knee lever to lower the 2nd and 9th strings but the changer will work for that set-up.
So….What I ended up with is a SD 10 with 3 pedals and 2 knee levers. This thing actually works! I think I went over every single piece of this guitar 6 times and got it working as smooth and quiet as humanly possible. The rollers on the nut were all cut different sizes and I measured each one and sorted them like a gauged roller system and that seems to have worked perfectly. The only issue is when you lower the E’s they return ½ a cent off from perfect, which is pretty much undetectable when you’re playing.
My dilemma now is that I really don’t feel it would be ethical to sell a piece of crap like this. While I believe I could keep it working for years to come, it could turn into a nightmare for anyone else. What would you do?
