In fact with new shanks and hammers, I dry down the shanks so that I obtain a mechanical sweat joint, as well as a good glue joint. Some manufacturers have a much looser fit than others and I am sure that they would be much easier to pull. However companies like Yamaha that have very tight machining tolerences plus dried shanks, you will find that on removing a complete set of hammers that has been treated with CA, you will tear a goodly number of shanks. For your imformation I change about 3 sets of hammers per month on a wide range of makes and models, and have been doing so for a number of years,many of the units at the university have been treated with CA glue by a variety of techs, and I presume many different types of CA glue. The Yamahas that have been treated in this manner I just replace with prehung shanks. One of many reasons is that I wish to maintain their standards with regards to hammer/shank fit Have a Merry Exmas Roger Jolly University of Saskatchewan Dept. of Music.
