You will find a jack spring hole reamer for removal of that glue for sale on page 50 of the new Schaff catalog. They've been selling those since before I started in the biz in 1969. I have found some companies depend on the tight fit of the spring and don't use glue but most of those I've had the mis-fortune to have to replace have been glued in. </blockquote> <div>   </div> <div>   I have a Currier spinet I tune & hate(always a fun afternoon), a fine specimen(read previous as dripping w/sarcasm) that had a whole set of bad jack and hammer return springs (cheap wire, I guess) that kept breaking. I had to replace the whole set of return springs and a few years later the whole set of jack springs, it was in an assisted living facility and the budget was there for repairs but not replacement. The only thing good about it was the pinblock, it wouldn't/won't give up. It is still going strong at this writing. </div> <div> </div> <div>I never did buy one of those jack spring hole reamers, maybe some day when I feel I have all of the essential tools I need and want some "extras"! <grin></div> <div> </div> <div>Mike</div></div><br>-- <br>You never truly understand something until you can explain it to your grandmother. --Albert Einstein<br><br>Michael Magness<br>Magness Piano Service<br>608-786-4404<br><a href="http://www.IFixPianos.com"> www.IFixPianos.com</a><br>email <a href="mailto:mike@ifixpianos.com">mike@ifixpianos.com</a>
