I was stripping and cleaning my front conical hub on my 72 OIF t120rv and I noticed these two sections on the spot where the wheel bearings would sit. the two blemishes are on the right side of the hub. I ran my finger on them and the ridge is pretty noticeable.
Is this something that can be sanded down or milled down to be still useable, or am I stuck with finding a new hub?
Thanks again for the advice, I know I ask alot of questions but these are my first forays into vintage brit iron.
One of the first tools we made in school. We would take old three corner files and grind the sides concave to produce three cutting edges. Two things to remember is to make sure the grinder's tool steady rest is right up to the wheel with no gap between it and the stone and not to over heat the metal. You should never let the metal get hot enough to show ANY signs of discoloration, even light straw. Keep water handy to cool the file as you grind. I have these made from swiss files right up through 12" versions. Like Bill said, one of the handiest tools in the box.
When I started as an equipment mechanic my boss had a scraper made from a file. I had to make one. Pretty much did as John said. I still have it today and it holds its edge better than the store bought ones I have.
I don't think you'll have a problem after removing those ridges. But if there's a tiny bit of looseness, a very small smear of loctite bearing retainer will ensure it doesn't move around.
Oh s**t, I recommended loctite with Mr. Healy listening. Off to the doghouse.
I was looking at it some more and I am wondering if the bearings will sit just before that mess in there. I am at the point of maybe looking for a different front end or another hub if it becomes an issue.
Pineapple--no need for a new hub--the one you have can be brought back to usable quite easily. Bearing scrapers are available at good engineering supply stores. Try it--very careful strokes applying quite a lot of force and small movement and the surplus material will come off. It is only an aluminum alloy so is pretty soft. The alternative is to take the hub to Hawaiian Tiger along with a few pints as payment---I am sure he would do it for you. As would I if you were living in Joooisey. But--an ideal opportunity to learn a new skill. HTH
No real need to switch to a disc brake front end. Folk lore has it that these conical hub type brakes were poor stoppers, but in reality, these brakes work fine when they are set up correctly. From the pictures, the damage on the bearing surface does not look too serious, and will certainly be easy to fix.
