FenwickG Report post Posted August 28, 2014 I have been searching for some time trying to find larger diameter radius gauges. I came across these ones on eBay. #161189892857 and #151203057943. These cover radius from 52mm to 100mm. For about $10.00 each I now don't have to make more gauges for fractional instruments, cellos and basses. Quote Share this post Link to post Share on other sites
