View Full Version : Question for Hogo
Adrian, I didn't want to highjack the Capek thread so I'll ask here. Also open to anyone else who may know. You spoke of shaving tonebars and it sounded like you were doing this through the sound holes. I think you've spoken of this before but I couldn't find it.
I have this chore to do as well and before I start, if you don't mind, I'd love to see a picture of your tools of choice for doing this. I may be overthinking this but don't want to take the back off if I can help it.
Thanks, David

Bryce, I read an article where someone went through the end pin hole to scrape them.
Well, it can be done several ways.... I don't think the endpin hole is best choice, unless you have tool that you insert through the f hole into endpin hole and then use it from there...
I work through one f-hole and look through end pin hole into small mirror inserted through the other f-hole... the tool I 'm using is a piece of wire (10" or so) folded in half to create small loop (shaped like end of ice ockey stick) on the working end to which I glued small piece of 80 grit sandpaper (1/2"X5/16"). The sandpaper is one of the more expensive kinds for belt sanders and is aggressive and works well with just very little pressure. The handle is twisted to give the handle some strength. The working end of the tool is slightly bent, so the sandpaper follows the top of the bar riding on it like on rail (you can make several tools for different shapes). Use is simple I decide where I'm going to take some wood and shape the handle accordingly so I will have at least 1" movement free without touching edges of f-hole. (putting some masking tape on the wire for safety is a good idea...) I'm trying to sand on the push stroke as this doesn't tend to deform the wire handle. with some training you can reshape easily whole tonebar. Of course you should measure it from time to time and look carefully for evenness.
I hope this helps...
