My dad picked this up as part of an estate sale in OK, it appears to be a hand tool. Overall length is about 10" and the gear head is 4" dameter.
Gears are free and when cranked the shaft rotates half a turn then changes direction goes haft a turn changes again. The bit on the end is flat metal held in place in the split shaft by a cotter pin.
This is a tool for lapping or refacing the valves in an automobile engine
I should also note. I did not find any sptampings, markings, numbers or any thing to help identify this.
Thank you for the info Slackjack. I never would have thought auto. My mind was stuck on a wood tool. Could you possibly direct me to where i coulddig up a few more details on it?
I don't see that Slack.
Good call Slackjack. There should be a rubber suction cup on the end.
No suction cup, and the handle is gone. But its still a cool piece. My dad was happy to find out what it was.
These early lapping tools did not always use a suction cup , valve heads were slotted or had two small circular indents that the tool fit into. Sometimes the tip on the end of the tool could be reversed for different indents. I just gave one these to a mechanic friend of mine , it also has no markings to identify the maker. The cotter pin in the end is correct , it makes the removal and turning of the tip a tool free task.
Rustfarm,
What you describe fits what is attached. The flat piece on the end has nubs on the outsides, and itdoes appear they are different on each side. Thank you for the info.

Thank you for the link.
I agree with slackjack. If you look at the end of the blade that is in the front of the tool, you will see two notch type protrusions, one on each end. these are to fit into the pin holes of the valve face, as many valves had. This would assist in gripping the valve when lapping the valve seat . ......hotairfan
