The galvanized coating ensures exceptional corrosion resistance, extending the lifespan of the pegs and maintaining their structural integrity even in challenging environments. You don't specify, but I infer you are drilling a hole with an axis parallel to the axis of the cast iron plug. In the Anglo world these are called 'Scotch Keys' and are quite often used to hold the rim (say bronze or alloy steel) onto a wheel centre (say CI or steel, eg for a wormwheel or a gear wheel). From around 1200 AD the use of a flat playing surface began to emerge. Often a plank, around 12-18 inches wide and 20 to 30 yards in length, was used as the lane with the pins set up as three rows of three pins. As it was impossible for all the pins to be bowled down within one throw, pins were respotted after each ball by the pin-boy.

Trustworthy Support: Rely on these Dutch Pins Masons Pegs to provide the stability and support you need for a wide range of construction projects, ensuring peace of mind and efficient workflow. I will use the ball-endmill technique, followed by StanP's suggestions for a tapered pin. it seems like the best way to get at least a reasonably round hole, followed by a good press fit. Game variations throughout the middle ages also include reference to a king pin. For some versions this was a larger ball whilst in others this was a larger, sometimes more ornate pin.

One way I've got around this is to machine the keyway on the shaft (plug, in your case) by lying it down in a vertical mill and using a ball nose cutter (as Racer Al seems to suggest) The modern game is most likely to be have had its roots in the ancient game of ninepins or Kegelspiel. Ninepins was popular with the Dutch, Germans and the Swiss.

However, the days of playing ninepins in England were numbered by 1366 when King Edward III banned it. Seemingly it was so popular with his armies that it was distracting them from their military duties as they were choosing a game of ninepins over archery practice. Strong and Sturdy: These masons pegs are built to withstand the rigors of heavy-duty construction work, providing a reliable anchor for your masonry projects.actually I'm not being entirely facetious on this naming thing: if he meant what you think he meant, it's hardly a novel technique requiring a special name)
