A tip of the hat to John Dewey for this. You should make a brace to support the lyre. Just use 1/2 inch thin wall conduit, 1/2 inch threaded rod, a nut, and rubber tips glued on each end. This brace set up makes for a very strong support. That lyre ain't going anywhere. Don't forget to take off the hinges attached to the rim before you roll it over. Otherwise the full weight of the piano will be on the barrels and attempting to rip the hinges out of the rim. A couple of books work as well as 2x4s. You just need to be able to get your fingers out after lowering and back under to lift again. And a good thick layer of newspapers work just as well as the tarp. Of course I only use 2 oz of CA for this treatment, so not that much is going to run out if any. I would add to let it sit for a good 30-60 minutes to let it all soak in before setting back upright. Then mist the pin hole field with accelerator before setting back upright, just to make sure there aren't any pools of liquid CA left waiting to run out where you don't want it.

With the lid gone we could roll the piano over on the straight side (after checking the lyre for stability and removing the left front leg) using the lyre as the pivot point. We left the lyre and two legs on the piano. We then rolled it all the way over letting it rest on some padded 2X4s on top of a plastic tarp (just in case some of the CA glue escaped). The customer and one of his drinking buddies helped me flip it over. The difficult part was laying down on my side and working in the action cavity. The CA fumes were very concentrated in that small space and even though I had a fan blowing directly on the work, it was still very strong. Next time I will use a more powerful respirator and some sealed goggles (the type they make for chopping onions will probably work). Also perhaps some sort of vacuum system to suck the fumes outdoors. ----- Original Message ----- From: wimblees at aol.com To: pianotech at ptg.org Sent: Monday, April 06, 2009 7:08 PM Subject: Re: [pianotech] upside down CA job report James Thanks for the update. It is always good to hear the results of a rather unorthodox repair. My big questions, and/or concern, is how did you flip the piano over and back? You probably told us about that 6 months ago, but I forgot.

I had previously treated it from the top, but because of the plate bushings, I didn't get good enough penetration to make much of a difference. Anyway, today I returned to do the 6 month tuning and I'm happy to report that the piano is holding well and all the pins feel quite good. If I didn't know that the pin block had been treated, I probably wouldn't have noticed that the pins felt different than any other older piano. I would definately consider using this technique again if circumstances warranted it. The piano, a Harrington grand, was not worth doing any major rebuilding, nor could the customer have afforded it anyway. This process saved the piano for what I hope will be a number of years, and for this customer's use, it worked out well. _____ The Average US Credit Score is 692.
