Examples, I had a Samick with slow jacks that spring stretching didn't cure, I treated the bushings with a 70/30(customer's rubbing alcohol) using Q-tips let them sit about 20 mins. Used their hair dryer to "cure" them and the problem was solved. Last month I had a 1970's Wurlitzer with jacks, hammers and whippens hanging. I brought it back to the shop, treated all with a 50/50 solution using a syringe and needle and let it sit to dry for a couple of days then re-treated it and let it dry for a week. I returned it to the customer and no more hanging jacks or slow returning hammers. I double treated it because it was a Wurlitzer of that vintage, at the time it was made Wurlitzer was making their own actions, too tight as it turned out. They were supplying their dealers with silicone to treat them. The problem with silicone on wood is it migrates and the problem returns. The added problem was that the word got out and non-Wurlitzer techs and tooners began using silicone spray from the hardware and auto supply stores which wasn't pure silicone like Wurlitzer had sent to it's dealers, so they compounded the problems, in some cases sealing the wood. Which is why I double treated and was careful to soak the felt and wood around it both times. Mike -- I intend to live forever. So far, so good.
