After speaking with Jo Gerber in SA and discovering that fixing a chipped mpc isn't that hard provided you use the correct material. I decided to give this a go. I had an old Alto selmer D scroll shank here which had a huge chip out of the tip. The chip was courtesy of a student who borrowed the mpc and bounced it on a hard floor.
I used a substance called liquid steel, an automotive product used to repair threads in alloy head, fuel tanks, water tanks for drinking etc... You can drill, tap a thread, file, sand, whatever this material once it has set. It bonds to anything, even glass apparently (never tested this out). After letting it dry for a week longer than it said was necessary, due entirely to having to much work on, I finally set about fixing this mpc tonight. I removed the excess material with a dremel and a variety of attachments, finished it off to a fairly close stage with some files and then tested it. I was knocked out to discover that it played, and played very well. Intonation is good, no reed chirps, plenty of volume, dynamics etc...
I would recommend this substance to anyone looking for an epoxy to fix huge chips in mpcs. It is non toxic, can be made to fit and moulded into anyshape.
Now all I have to do is work out how to make the tip larger without destroying the mpc. some mor efun and gmaes in the coming weeks I fear.
A special thank to Jo Gerber for his insights and help.
