|
|
This graft has arrived for repair. It is a perfect fit and a simple reglue will likely work well but your comments on 2 questions would be appreciated.
1- The previous glue was a hide glue... is there an advantage to washing the old glue off? my concern is that if I wash, then I might distort the wood and get a less than perfect final fit.
2- the fit is now absolutely perfect... how would the cuts have been made originally?

When I have done them, I made the initial cuts with a very fine pull-saw. but the final fit was done with a stiff, straight scraper.
If the fit is as good as you say, and there is no excess glue (which may be why it failed-- possibly all the glue was squeezed completely out, causing, in effect, a "glue-holiday"), then I think I would:
1. experiment with clamps until I knew EXACTLY how I was going to secure it, then
2. try it again, rapidly, then
3. go ahead and glue it with fresh, strong, hot hide glue, and clamp it.
Good luck with it. _________________ Chet Bishop

| The scarf joints on either side look abnormally short and the overall configuration is wrong - not done by a trained repairman. |

Granted, this is not a traditional graft, but nonetheless it was done with considerable precision... On the cut surfaces, there is no indication of any area where the contact of wood to wood is less than complete, nor is there any indication of areas of thicker glue. My guess is that this was not done by hand, but I can't imagine what method might have been used.
Thanks for your thoughts!
Cheers, Mat |

Following the thought of an untrained repairman, what is that white stuff that seems to be bushing part of the G peghole?
I suspect other mischief also, eg glue type (which may be incompatible with hide glue).
In any case, it looks like a pretty cheap instrument, so to much contemplation is probably misplaced. |

Janito- You are right... that white is part of the bushing for the peghole... not sure what the material is, but looks like some sort of paper.
The glue appreas to be hideglue as it gets sticky quite quickly with a wet finger.
You are right in that it is a cheap instrument... but they tell me it sounds terrific and with good volume... and with the effort that went into the graft, it must have been an instrument very desireable to the musuician.
As for contemplation... I like to give every instrument "the works"... never know what I might learn and apply to a good instrument! But then if I were to make a full living at this then I might be more inclined prioritze my contemplation time!
Cheers! ... Mat |
