If you re-hair violin, viola, cello, or bass bows professionally or as a serious hobby, you know you need a good jig to hold the bow steady. The Juzek 101601 is a classic, reliable tool for the job. It's a simple but clever design with a padded surface that cradles the bow securely without scratching the delicate wood or frog. The best part is it's fully adjustable to accommodate the different lengths and shapes of bows from a tiny violin bow all the way up to a huge double bass bow. It clamps onto your workbench and gives you both hands free to carefully remove the old hair, clean the frog and tip, and tie in the new hank of hair. It's an essential piece of equipment for any luthier or repair shop. It makes the whole re-hairing process safer, more precise, and much easier. If you're tired of juggling the bow or using makeshift setups, this professional jig is a worthwhile investment that will last for years and improve the quality of your work. A must-have for serious bow maintenance.
