SLITTING AND DRIFTING A HOLE
Hans begins this demonstration by explaining the purpose and design of each tool.
These tools are designed to measure, slit and drift.
Brian measures, then slits, the first hole on one end of the bar.
Once the hole is slit, he opens it with a drift, expanding the hole, and flaring the sides.
Using a tool designed by Hans, the position of the second hole is measured from the first hole so that each piece will be exact.
Slit and drifted square holes with beautifully flared sides.
