>I have asked a few technicians {Inc supply houses} here in the UK but no

>High Pressure air blasting I know about. This is something different.
>If someone could let me know what he was talking about .
>Q Does anyone spray their actions clean ?
>Q If silicon beads is a no-go , what if anything , is the alternative ?
>Q Is the rest of the world silicon spraying their actions , except me ?

Dear Alan:
To familiarize yourself with this process, I suggest reading Bill
Spurlock's series of articles in the January to March 1992 issues of the
Piano Technicians Journal. We equipped our rebuilding shop likewise a few
years ago and we have not regretted doing so. The quality of our work and
the efficiency of our methods have increased tremendously. You can also
purchase the reprint book titled, General Repair: Reconditioning of Parts,
Tools and Felt Work, which includes the articles on Glass Bead Blasting and
is available from the PTG home office.
