I should have mentioned in my original post, I have done a lot of CA juicing, including pianos like this one with tight bushings and loose blocks. Bushings are no problem if the pin is so loose that string tension has pulled it away from the bushing on one side - then you can easily flow enough CA down to the block. The procedure is noticeably less effective when there is no gap between the pin and the bushings, sometimes not effective at all. Meaning, you can tell by the feel of the pin that it is only being gripped by the bushing, not the block. No pin wind-up, telling you it is gripped only at the top, not down in the block, and once it begins to turn it spins freely. Anyone out there had similar experience and tried drilling down through the bushing? thanks Mike On 2/14/2011 9:22 AM, Cy Shuster wrote: > I use the thinnest CA and a veterinary hypo needle.

I believe this person had not tried it yet, but was considering it. I have a situation (newish Asian grand, tight bushings, loose block) where this might be the only way to get the CA where it belongs. Has anyone tried this technique, and if so, with what results? >> >> thanks >> >> Mike
