Where does a hobbiest like myself get a chamber reamer sharpened?? Thanks guys.

Dave Manson at Manson Reamers does it, and I'd suspect that Dave Kiff also sharpens reamers. Who made the reamer?

Note that the price will depend on the amount of damage. IOW "normal" dulling is one thing, but if the front end of the reamer has been burned (easy to do when cutting stainless) than the price will be higher (I have one that needs to be cut back, just for that reason)

The only name it has on it is Fuller Tool. Nothing looks burned on it, just won't cut.

I don't know Fuller Tool as a chamber reamer maker, but anything is possible I guess.
Get ahold of one of the guys I mentioned above (I know Dave Manson posts here now and than) and see what they have to say

Or, locate a local machine tool sharpener and have them resharpen it. I though Fuller just made brushes.

Fuller Tool was a tooling company in the Detroit suburbs during WWII and the post-war period that made the occasional chamber reamer--some were sold through Brownells way back when. Clymer bought the chamber reamer business, with the Brownells connection, from Fuller c.1959.

Fuller chambering reamers were made well for their era, although the specifications to which they were made were sometimes suspect. We'd be glad to inspect it for you and advise whether it's worth re-working--will only cost you postage to find out.

Works for me. I'll be sending it to Dave. Sure doesn't look like its been sitting around all those years. Very well taken care of.
