Most skilled flameworkers have been forming their own ground joints using a reamer and a waxed glass ground joint to finalize the tapered fitting. we designed this line of tools as a two part joint forming tool .use the reamer to achieve 90 percent of the tapered fitting and the brass 'plug' to finalize the shape. both parts are the width and length of a lenz or accugrind manufactured 10-1 ground joint.
Joint forming tools should be waxed each time they are heated. for best results, slightly preheat the plug in the back flame before using. over heating the tools while forming the joint may causes the 2 parts to stick. if this occurs the plug has gotten too hot. these forming tools do take a little getting used to and detailed instructions will be included with each item to help with the learning curve. we chose brass instead of graphite for this product for longevity and consistency of the formed joint shape after multiple uses.
