Here's a very nice two-pinion hand drill type of tool with a cast handle and... some sort of a non drilling end. Any guesses?
I'm sure the kids could commandeer the tool for playing submachine guns...
Solved! (see comments) Turns out it's a device to grind valves with a clever action, the half gear on the crank only engages one pinion at a time and so it reverses every half turn for proper valve lapping motion. (Thanks, Meddleshop)
The half circle gear would make the business end spin left - then right, so not a drill. Blowed if I know...

Valve lapping tool ?
ReplyDeleteyeah, it's a valve lapping tool. the 2 pins on the business end are from a time when valves came with holes for these tools. I've never seen one like this, the ones I have are designed to just crank the handle in one direction and the gearbox does the reversing of rotation.
ReplyDeleteI looked again, clever! the half gear on the crank only engages one pinion at a time and so it reverses every half turn
ReplyDeleteThat's cool. It's fate was to be replaced by a stick with a suction cup lol.
ReplyDeleteThanks, guys. It is quite the tool. if it is still at Liberty Tool the next time I'm there, I will have to buy it:-)
