<p>Hi bob, any bending of the metal was done cold.</p>
<p>When working on ply plates keep in mind that heat may often soften the glue between the laminations and as you apply your tools you may separate layer after layer of the plate. Messy job. </p>
<p>I also consider adding a brace behind the back edge of the plate going from X brace leg to x brace leg, once the top is flat. I have to judge each guitar on its merits as far as quality of build, sound, and the care [or not] given by the owner.…</p>

I have to judge each guitar on its merits as far as quality of build, sound, and the care [or not] given by the owner. Also, a loose brace somewhere may have caused the problem in the first place, so I look for that also. Although I can usually hear if a brace is loose.</p>

<p>I am inspired by your tools - I have a spokeshave and stanley 78 blade I could attack to wood (I don't have a torch to bend metal). However, I'm still nervous. Would the aluminum plates from the <span>TJ Thompson Belly reducer be enough to heat the plate? </span></p>
<p>My bridge plate and guitar top are both plywood. Does this put me at increased risk for damaging the top? Does anyone know of a video or really great resource (with pictures) for this? I can't find anything. </p>

<p>Hi Bob -</p>
<p>The overlay I used was Bubinga 1/16" - 3/32" thick. I was dealing with a plywood top, and a plywood bridge plate, glued on with some strange thick and translucent glue. Even after heating, it showed no signs of wanting to loosen, and I did not want to damage or destroy the top.</p>

<p>I have a guitar with a similar bellying issue, but not as severe as yours sounds. The bridge plate is plywood (with a mahogany veneer oddly enough). I used the TJ Thompson Belly reduce to flatten the top. Now I'm debating what to do with the bridge plate. I have no tools (or skills) to remove the plate, but I'm worried about adding a piece of hardwood and thickening it even more. Is this something I need to worry about?

<p>I don't really feel like buying another $80 tool to remove the bridge plate and also risking hurting the top more. </p>
<p></p>
<p>Any help would be appreciated!</p>

<p>Taffy, those are great demonstrations of top repairs. I was obviously way too pessimistic at the beginning of this conversation when I suggested that it couldn’t be fixed! </p>

<p>I wonder what chord they were strumming when that gave way. Well, at least it saved the time of bridge removal.</p>
<p>Nice job. Did you inlay spruce under the bridge?</p>
