Re: Bowlbacks of Note
Jim, where is the warp on yours occuring? How bad is it? On the one you posted from Bernunzio's there remains a small tab of wood which in effect segments the F hole. That was either missing or omitted on mine and the intrados-es (don't know what else to call them) at both top and bottom of the treble side were both warped, one in and one out.
I'm sure you could fit some kind of brace under there but my fear is that it would have to be pretty deep or pretty stiff in order to hold that deflection out at the 'floating' end of both the brace and the 'flap' of the top. (I'm waving my hands around trying to explain this right now.)
If you are missing that tab (and if was up to me) I would try to cut a brace to span the f-hole void. The brace could be shaped so that the piece spanning the void would be flush with the top in a sense recreating that original tab that was left in the top but being much stronger due to the depth of the brace. You could probably glue it up with just one C-clamp snaked into the f-hole.
I sold my Waldo to a fellow out west who was also way into them. Maybe not as much as Paul. I enjoy seeing those old Waldo ads. Isn't there a dedicated Waldo thread? I'll try to track it down and link these two together. Great stuff.
