I am firmly convinced that CA treatment of pinblocks improves torque, in most instances, by a lot! ( Except on pianos treated with Garfield's Pintite treatment. I would NEVER use Garfields pintite solution on a piano, or buy one that had been treated with it except as a complete rebuild.) I also have had success, but not anywhere near as dramatic, using glycerin and alcohol treatment with some pin tapping. Many of the pianos I treated this way fifteen years ago are still holding. My question is this: In your opinions ---- Has CA treatment for torque completely supplanted the glycerin/alcohol treatment, or is there a middle ground where glycerin might be used on the first go-around, and then 15 years later CA treatment when needed again? I personally think that for very low torque values, CA is the only way to go. I am just not sure whether or not to NEVER use the old treatment again. I would appreciate any opinions. Thank you, Bill Simon Phoenix
