Original message From: "Avery Todd" To: Pianotech Received: 9/8/2005 4:15:52 PM Subject: Re: Removing tuning pins with the Milwaukee Drill Ross, I totally disagree! How else are you going to get them out. Do it slow,= and MUCH more heat builds up! Avery At 01:08 PM 9/8/05, you wrote: If you spin tuning pins out, you're going to scorch the holes in the bl= ock. You don't want that. Ross White ----- Original Message ----- From: William R.

Interesting...... Also, tried to email you about the keytop thing, but got rejected. Any= way, I'll await receiving the keytop being sent to me first, and if it doesn= 't work, I'll let you know. And, thanks. Respectfully, William R.

I know the pins WIL= L get hot no matter what, (I tested this by using the very lowest rpm possibl= e without stalling) but it seems to me that the main thing to avoid is "spinning" the pin in place when/if it stops rising outward during remo= val. I try to use lowest rpms to remove each pin, then releasing trigger whe= n it's almost out, letting the drill slow to a stop at which point the pi= n drops out...ideally. thoughts? Terry, An interesting experiment: 1. Remove a tuning pin with a Brace and Bit;= immediately test it for heat. (it will be hottern' hell a first touch.)= 2. Remove a tuning pin with a Reversible Drill as slow as it will go. Test= it for heat. (it will be hot and getting hotter.) 3. Remove a tuning pin w= ith a Reversible drill running at/or around 600 RPM. Test it for heat. (It wi= ll only be warm, but will heat up rapidly as you hold it.DAMHIK!<G>) This phenomenon is kinda like Microwaving a spud.<G> The answer is spin them= out as fast as you feel comfortable with. I usually remove a whole set in a= round 15-20 minutes, using my 40 year old Wen Reversible Drill.<G> (It too, will spin the shop, if'n ya ain't careful!) Regards, Joe Garrett, R.P.T.
