Yeah, I didn't think it was a really great solution, but since Frank sort of implied it was for occasional use I thought it might be workable. I couldn't find a 'real' reel spindle for the picture, so I just put the adapter on a hand rewinder - just to get the idea. The Kelmars arms have the drive dog, so the reel wouldn't free spin.
There's an amazing variety of ways reel manufacturers have designed just the spindle / drive dog area over the years, so I know not everything will work with every other thing. Many reels will allow you to place a 5/16 reel with the key on a spindle, yet leave the drive dog in place. The classic Goldberg 2000ft cast reel has a 'inset' (where the finger holes are) so they won't hit the dog. A problem I do see though is the adapter will probably slide off when you remove the reel.
Anyway, I was thinking about making a 'product' out of this, and I thought I'd make something and send it to Frank to try. There's probably not much of a call for this type of thing anymore, but OTOH, it's easy to make.

Yikes, what have I wrought?!
OK, let me back up -- the whole reason for the original question was because we got some 6000ft reels donated to us. 3 of them have standard keyed 5/16ths holes and 2 have the 1/2in holds. I wanted to be able to use the 1/2in if I could, and since we do use 2000 footers most of the time, plus now the other 6000ft-1/2in reels, it would be advantagous to be able to switch back and forth as necessary.
BUT, bottom line is, we are only talking about two reels with 1/2" holes. Soooo, no sense going nuts just for two reels (anyone want to swap 2 floating hub 6000ft-1/2in reels for ones with 5/16ths holes?).
From what I can see, Steve's Kelmar 35/70 arms solution would solve the problem satisfactorily but they would cost big $$$, which pretty much kills the thrill of getting free 6000ft reels, no?!
The adaptor in the picture you posted John seems like it would almost get me there, but then that gave me another idea. Maybe my original approach was backwards -- why try to adapt the spindle on the arm when it would be just as easy (maybe) to convert the two reels? I am thinking of the Goldberg 2000ft reels which have a bore hole larger than the 5/16ths key hole; they use a plug which brings it down to the needed 5/16th key. key. I don't know exactly what holds these inserts in place other they are force fitted -- on occasion some have loosened up on me and I've just spread the key notch apart abit and then rammed it back in the whole (that's what she said).
Seems like if I could fix these two reels with a simple plug like that, it would put this whole thing to rest.
And thanks for the offer of that test part, John. Very kind of you.

So, Frank, your question is now equivalent to Scott's. I left off with a joke, since I'd hoped someone else was a bit more certain of the answer.
Assuming the 6k reels are built like the 2k reels, all you need is an arbor press (or a hammer if you're going to do it Wrong) and the right size inserts. Though it's probably a good idea to use some LocTite 660 (use primer if you're pressing into Aluminum). I don't know if the inserts are available from Goldberg, though. "Probably."
Remember, though, eventually your 6k reels will probably shear off your 5/16" key.
Scott, I'd be happy to do yours if you bring me the parts.
