Enjoy before and after? We upgraded the skins, flesh hoops and lugs, as well as refinished a customer’s 6.25″ x 7.25″ bongos. They are in great shape with no need for crack/stave separation repair. I mounted/tucked a .9mm horse skin on the macho and 1.2mm steer skin on the hembra. There was very little space between the shell and crown.
