Another way to wreck a driver

You may recall that one of the previous methods to wreck a driver was to drill the hole for the crankpin off-centre. Actually, that didn’t completely wreck the driver: once the spokes had been taken out, it looked salvageable. A short length of steel soldered in the hole and filed flush made it look as good as new.

When drilling the new hole, however, I soon discovered that it was not as good as new. In actual fact, it appears that the drill bit ripped that tiny piece of steel out of its hole and used it to break itself. Then it whipped the steel plug and its own broken end around to make a mess out of the wheel boss.

So, the next time I get the hole off-centre, I will be starting from scratch. Surely this must be the last way to wreck a driver.
