PTM 2021 March Convention

Fred Sturm

Precision Key Service​

Efficient techniques to size and lubricate key bushings and balance holes, including precision ironing and using steam to rejuvenate compressed bushings.

What's in the episode ?

The feel and function of the keys is a very important element in both grand and upright actions. Precisely sized bushings and balance holes can make all the difference in the world to both feel and function, and appropriate lubrication helps keep it that way. We’ll look at sizing and ironing bushings, whether they are too tight or too loose, using controlled heat and steam in fast, consistent and ergonomic ways, as part of a comprehensive key service protocol. Efficient procedures mean top quality results at affordable prices.

"I liked the way the presentations were prepared for this format, with videos and the teacher narrating what is going on. I also like the Q&A. An essential part of every convention is having someone (usually me) ask what seems like a dumb question but everyone learns something anyway.
