How long have you found it takes to cure before letting the students pound on it (pedals)?

I carry it in my case now, the two tubes are pretty small and don’t weigh anything. Another pedal repair job it is useful for: the stamped steel pedals formed into a U shape, the pivot rod knurling will wallow out the hole. Just put the pin in place, slather JB weld around it, even fill the middle area of the pedal with it. It works great. I ran across this problem 40 miles from home. I just went to the local auto parts store as they all carry JB Weld and bought some.

The pedal had been repaired once already, possibly twice. It had been brazed, I believe, then "reinforced" with some thin metal straps attached with nuts/screws through the vertical holes. When I first encountered it, it was broken in two places. I went to Lowe's or Menard's and bought some aluminum channel, and also some 2mm flat aluminum, and some JB Weld. First experience with JB Weld and I am very impressed. Mixed it up and slopped the channel full, dropped the pedal parts in, and covered the top with the 2mm flat. Let it cure for about a week, filed off the excess and installed it in the piano. I'm pretty sure it's about 100x stronger than original. Only thing to watch for is that the opening in the front of the piano is large enough to accomodate the pedal's larger stem, which it was in this case. None of the aluminum is visible with the piano in its normal configuration (i.e. knee panel on) Paul Bruesch Stillwater, MN On Tue, May 12, 2009 at 4:39 PM, <wimblees at aol.com> wrote: Chet If they are broken, it's the cast iron stem that usually breaks. A welder should be able to weld the stem back together. I have done that many times.
