We have here at BYU a 1976 Baldwin SD10 that has jumpy tight pins so badly as to render it nearly untunable (at least within a reasonable length of time). We have tried to loosen them up before (heat) with no success, so before I go to the trouble of replacing the block, I thought of this one last ditch effort. We applied the Protek on the 11th of Jan., and I figured by Friday the Protek would not creep or otherwise wander but be "set up" by then, so obviously this hasn't withstood any length of time test. We found that within the hour the pins were much less jumpy in general, and by the end of that week the pins felt about the same as they did on Monday. Today I tested some of the ones that were most jumpy originally, and some were still a little too jumpy, but with a "steady pull hammer technique" I could get smooth action from the pin, whereas before, I couldn't. However, I put 4 more drops on those that were still jumpy anyway, to see what'll happen.
