Griffin 18mm Joint Reamer (Alum.)

Most skilled flameworkers have been forming their own ground joints using a reamer and a waxed ground joint to finalize the tapered fitting. This line of tools is 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 the length of a (Lenz or our Indian) 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. Overheating the tools while forming the joint may cause the 2 parts to stick. If this occurs the plug has gotten too hot. The tool heads are made out of brass instead of graphite because of the longevity and consistency of the of the formed joint shape after several uses. This product is 18mm and has a brass head and aluminum handle.
