Assault RC Revolver gluing jig

Posted: 07 Jun 2021 02:01 AM PDT

From Assault RC, the Revolver gluing jig spins on a ball bearing turn table to eliminate the stress of the pulling the tire bead back evenly. By simply putting the top piece on the and twisting it a 1/4 turn you evenly open the bead up in a matter of seconds with equal amounts of pressure all the way around therefore when releasing the top after applying the glue you eliminate most of if not all of the risk of the tire lifting and warping giving uneven side walls. After twisting the top off you pull the tire out, put a band or tape around the bead for pressure and let it sit.
