Below is the form that I use for making a one piece BC entry pipe w/ the long finial. Although this form has made a few, the last one I made is a 2 piece that's soldered together and I'm debating which will be used in the future. These long finial BC entry pipes aren't commercially available but are found on most BC LRs, so really should be incorporated. The finial of the 2 piece is also formed w/ these same form blocks. The small block is the shape of the lower forend minus the thickness of the brass. I use .040 annealed sheet brass and constantly anneal the brass during the forming . The "pipe" shown is one piece.
