Bottom board...warped.<br>Insert for said bottom board...major warped. Reason: finish only on the<br>face veneer! Yikes! This is on an 1855-70 German Upright, I just completed<br>a full rebuild/redesign/whatever. (You'd think the Germans would know<br>better! (sheesh) The insert had ripped all it's mounting screws out of the<br>bottom board frame it was "mounted" on. So, I took them puppies out to the<br>woodshed...literally! (it's where I do most of my rattle can finishing<br>projects) Sprayed my favorite elixir, shellac, on all the bare wood<br>surfaces. (Sevveral coats, in fact) After each coat the insert seemed to be<br>much flatter! Hmmm? (said I<G>) Now that I have a major amount of shellac<br>finish on the insert, the panel is almost flat, negating, for the most<br>part, my exotic plans for slitting the panel and wedging it straight. Go<br>figger!!<G> I'm now doing the same to the other panels. They are not so<br>"major warped", but do have some issues. Hopefully, the shellac treatment<br>will get things back in line enough to just leave well enough alone.<G><br>Anyone else done anything like this?<br>Regards,<br>Joe<br><br><br>Joe Garrett, R.P.T.<br>Captain of the Tool Police<br>Squares R I<br><br></div></blockquote></div></td></tr></table>
