Emailing: bridge pin remover (jack houweling) From: Fred Sturm <fssturm@unm.edu> Date: December 13, 2006 7:41:29 PM CST To: caut <caut@ptg.org> Subject: [CAUT] Bridge pin removal Reply-To: College and University Technicians <caut@ptg.org> Hi all,     I wonder if anyone has some good advice for removing stubborn bridge pins. Beyond grabbing them with vice grips, grunting and cursing <g>. I'm thinking heat, but don't want to cause too much damage to the hole. Would one heat with a soldering iron, say, 15 seconds (of course depending on temperature of iron), then let the pin cool before pulling? That's what I am planning, but thought I'd see if anyone had a better plan.     BTW, my reason for removing solidly attached pins is to replace with new, due to zinging sounds. I found one loose enough to pull, and it had the definite common wear profile, with a sharp feel to the finger. Meaning a nice bit of metal shaving sitting there. I pulled a few unisons of strings, dressed the capo, and restrung, and the zings had reduced but not disappeared. So I'm hoping bridge pins will be the magic cure.

Or, just grunt it out with vise grips. Worn bridge pins can cause zings.  That's why I wait until at least the fourth chip tune to do the final leveling of bridge pins.

I found your checking with thirds rather interesting.  I can tune a harpsichord in about 15 minutes or less with this temperament, and I never listen to thirds beyond checking the final F-A.      Isn't the whole point of the method that you just whip around the 5ths?  The thirds take care of themselves.   I'm very happy you published this.  While there is a huge amount of disagreement and controversy over this tuning, it is really very nice, very usable, and very fast to lay on an instrument.  The only temperament I find faster is 1/4 comma meantone. I highly recommend you all read this, and then go find the original online on Brad's website, which is nicely referenced in the article. best and back to harpsichord building here, Anne From: Ron Nossaman <rnossaman@cox.net> Date: December 13, 2006 10:24:22 PM CST To: College and University Technicians <caut@ptg.org> Subject: Re: [CAUT] Bridge pin removal Reply-To: College and University Technicians <caut@ptg.org> Fred and list,         Personally I'd like to see a small vise grip attached to a slide hammer.

Greg Newell Fred, Greg, and all the ships at sea, The slide hammer works great.

The dent puller I found that was close to the right size was still too large a diameter rod to thread down to the vise grip size.

Interestingly enough, the slide weight fit over it just like it did the bigger rod that it was originally made for. Go figure... <G>  One end of the rod screws into the Vise-Grip (with a wing nut to lock it), and the other end has a double nut to act as a stop for the slide. The sloppy slide fit still hammers just fine.

First insert a threaded rod to fit the vise grips. I then put a metal sleeve around the threaded rod, this will make it easier for the weight to slide and is gentler on the hands. Then ad a couple washers and nuts. Works fine.
