Mystery tool

[lugnut]

I bought this tool thing at a yard sale this morning and don't know what it is. It's built like the early 20's and 30's screwdrivers with a heavy wood handle. It's 14" overall length. The guy that sold it to me had no idea what is was or for. Anyone here know? ???

look like it would make a very impressive weapon.

I use them all the time. It's a scraper. You hold them in your hand and you can use them to scrape a small amount out of a bore with the lathe running. The one i use all the time has three sides. But that one would be handy sometimes.

Thanks Wes, someone at the yard sale where I bought it at said they thought it might be some sort of wood lathe tool. He had two of them, I only bought the one.
Thanks again

Any time) I went out to the shop and made a quick video so you can see how I use mine. You can deburr the edges of a hole or remove metal from a bore if needed.

Mel,

The type you have there is a bearing scraper, from the days when all bearing surfaces were mainly just plain metal, after a bearing shell was cast into say the main block, a specialist artisan used to scrape away minute bits of metal to get nice free running and accurate fits.
If you look at the more expensive machinery, and see on the bedways what looks like a sort of engine turning, that is in fact where all the ways have been hand scraped to get them perfectly flat. In fact having them hand scraped is still done today, because the bedways last a lot longer than ground ones. The reason being, oil is trapped in the minute recesses and so the bedways don't come into as much metal to metal contact as when they are ground.
Lesson over, and Wes has shown a very good use for them, as gravers when hand shaping metal on a lathe.

BTW, you can still buy them new from tool suppliers.

Thanks guys for all great help :bow: But it is a little sad though because now I don't have a "Mystery Tool" any more. But rest assure I will get another on next week. ;D

still has lots of use as a bearing scraper, I've used them on a model's split bronze bearings and eccentric straps. if you ever end up with tight fit on boring, scrap them in with blue for that perfect fit.

Mel: As already mentioned, your mystery tool is a bearing scraper. I used them when I was a teenager and my Father and I repoured the babbit bearings in some cherry pitters for our cannery. I wish I could remember more about doing that job, but I do remember we had asbestos fibers and dust mixed with gear oil to make a "Dam" at each end of the casting housing and we blackened the shaft with acetylene smoke to keep the babbit from sticking to the shaft.

I have used scraper exactly like Wes showed in his video for years, and never knew they were used for anything other than deburring.
