The Cole Drill gloat

One aspect that looked a bit odd at first, was that the pressure screw is fabricated from 2 separate pieces. The top hex section appears to have been pressed or shrink fitted to the threaded round section.

The thrust bearing I have is the shielded, integrated ball bearing type such as McMaster 60715K12 (if this link doesn't go directly to it)

Thanks. That certainly explains why the ratchet isn't reversible, anyway. --Glenn

It sure would. Everyone in the Federation knows that 'Setting a Phaser to maximum' causes it to explode, in a few seconds. You must be a Klingon infiltrator!

In Lautard's 3rd Beside Reader there is mention of the drill adapter being "three sided". Perhaps there are three screws to attach any size drill to the Cole drill?
