I use a lot of Chinese violins for various experiments. As they come, the fingerboard does not make a slight rise at the end of the neck, which I like. Otherwise there seems a kind of "sad" ...

Years ago Howard Core sold "mousetail files." He does not usually drop discontinued items, and it is worth a look.

They were not very expensive. I recall they were pretty sharp at the ...

Nobody mentioned this, so I will. A good hobby shop sells all sizes of model train mini-lights. They are all 12 volts. Turns out the BIGGEST ones are only about a cm long and 4mm diameter. I take ...

If that was for a back in my formula. I like 1.3-1.4 as you indicated for your data point. 1.1 is starting to seem like a weak back, but I do not have data for what was "good" or "ba ...
