with the centers out to each end of the tip. Get some low melting silver solder and join the 3 pieces.
Use the lowest flame possible to melt the silver solder, as to much heat will or can crack the carbide tip.
When done let cool in the fixture. When cool set up between centers of the lathe, set tail stock over so
you will have a 1 degree included taper per inch from the front or cutting edge of tip to the back.
After this, grind the primary land. This will have to be ground to absolute center. After this is done, heat
the drill tip up and remove the centered ends. Grind the remaining silver solder from the carbide tip, if
the holes are plugged, drill them out. I have found that welder's chalk rubbed into the holes of the tip will
help to keep the solder from plugging it. The drill can now be mounted to the drill tubing.
The V tubing can be purchase from High Standard, or Danjon, address is in the back of the book under
suppliers. I would recommend that you buy the first one from the suppliers. This will save you some
headaches on your first barrel. The drill will last for several hundred barrels if you have no accident, and
you take care of them.
