I am replacing an ejector (top) on an SKB 28 ga. The ones I have fitted before have had the rim already set up and only required fitting. This one (28 ga) came in without the cutout; I just noticed it or I would have sent it back to SKB. Cannot figure out how to do that. I don't have a milling machine, only a milling attachment for a Southbend 9" lathe and have not checked to see if I have an end mill of the correct size.) Thanks Gil

Please take it from one who has fitted and rimmed a lot of extractors . Do not mess about and risk ruining the work you have already done . If you cant borrow a correct rimming cutter get someone else who has oneto do it for you .

Gil, Not sure what your ability is as far as machining but if you have a 4 jaw chuck or face plate you may be able to mount the ejector in or to one of these and cut the rim groove with a standard lathe tool. Going to take some thought to get a solid mount and take light cuts but I think it would be doable...

Or get one of those terrible Parker guys to lend you a Clymer chamber reamer for an hour or two. In five minutes, you will be done.

There are a couple of 28 gauge chamber reamers with rim cutter and pilot floating around the PGCA forum. The reason is that early 28 gauge Parkers had smaller than normal rim recesses that needed to be enlarged. I did my first 28 gauge Parker on a Bridgeport vertical mill, right angle setup. It was a nightmare that I don't want to repeat. A PGCA member responded to me and offered to lend me his reamer. I don't remember his name. The Clymer reamer I borrowed made the rim cut a five minute job.
