Most skilled flameworkers have been forming their own ground joints using a reamer and a waxed glass ground joint to finalize the tapered fitting. Griffin has designed this line of tools as a two-part joint forming system. Use the reamer to achieve 90 percent of the tapered female fitting and use the brass “plug” to finalize the shape. Both parts are the width and length of a (Lenz or Accugrind) manufactured 10/1 ground joint. Slightly preheat the plug in the back flame before using. Overheating the tool while forming the joint may cause 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 are included with each item to help with the learning curve. Scott Griffin chose brass instead of graphite for this product for longevity and consistency of the formed joint shape after multiple tool uses. Shaft is made of high strength steel and features an all aluminum handle and brass reamer head. Select the size(s) you want in 10mm, 14mm or 18mm diameter.
