I’m sorry! That happened to me a couple months ago. Try eBay- there was quite a few good ones pretty cheap. Also, fiddleman has the scratch and dent sort of seconds and they were fairly reasonable too.
Steve, that’s a great idea. I have been rubbing my bridges and nuts with pencil “lead” for the various instruments I have for many years but never thought to use pencil graphite on the screw to my bow frog. I just did that to my favorite bow and wow….Thanks for the tip!
