The spacer should be a close fit on the axle so that it bears only on the inner races of the bearings. If the inner diameter is too big it can bear against the bearing's shield instead.

In short, I'll let you know in a week or two when I've got all the parts and am mocking it up.

Oh... I guess I didn't post here. Everything is bolted up and it rotates nice and smoothly, with no binding whatsoever. I have to rebuild a caliper and make a brake pedal, but the hard part is done.

There's plenty of clearance on the sides of the tire to the swingarm, and I'm really happy with how everything fit together and works.
Stock tire is a 130/90/16, and is 25.2 inches in diameter.
The 78 CX had a 18" rim with a 4.00x18 tire, for a diameter of 26 inches.
The 78 rim with a 110/90/18 on it is 25.8".
The 78 rim with a 120/90/18 on it is 26.5".
I'm running a 5.10x17 (stock size for the GL1000 rear), and I've measured it at 25.9" in diameter (well, I measured the circumference at 81.5" and calculated the diameter)
The Goldwing rim with a 130/80/17 it will have a 25.2" diameter, same as the stock 16 incher.
In truth, I was kinda hoping for more wheel-based RPM reduction. But I'll take it.

The stock rear for the GL1000 is 4.50-17.
Thank you for the update. It looks great, and I'm glad it worked out!

Hrm, you're right. But, the 5.10/17 fits nicely and is not overly pinched or rounded, so I'm sticking with it.
Charles.
i tried reading your blog, and while i do like the background, it makes it horrifically hard to read the grey text :/

Yeah, my blog hasn't been updated in years. But there should be a dark overlay on top of the background pic, which makes the text legible.

Yeah, don't use Microsoft browsers. It looks fine in Chrome, Firefox, and Safari.
One day I'll put more content in there and completely revamp it. But today is not that day.

Looks OK on Firefox.
would a comstar 78-80 rear rim work for this conversion as well?
how are you mounting the master, and what linkages are you going to use with it?

The GL1100 17" comstar is a much easier fit. It's already got the correct spacing, all you need to do is replace the bearings and machine a new distance collar to put between the bearings. (You might get away with using a CX distance collar, but you'd have to measure and make sure). You'll still have to machine a spacer or two and a collar for the brake caliper stay, but if you have a lathe that stuff is easy.
I'm using a CBR929RR right footpeg/pedal/master cylinder setup as the basis for my rear brake. I could just bolt it on and weld a tab on the frame for the bottom mount, but I'm trying to do this bike with as little frame modification as possible. Everything is currently un-doable by using stock parts. My intention is to Cut off the footpeg mount on the reversed Custom footpegs that are currently mounted on the bike. I'll weld a plate to the mount and attach the brake pedal bits from the CBR controls. I intend to use IMS Supersport pegs, for which I already have procured mounting brackets. So it's all a matter of assembly and welding.
I might work on that this weekend, while I'm waiting for a new ignition switch.

Are you going to have the caliper hanging below the swingarm like that? I don't think I'd want it hanging down on a bike I was taking off road...
FWIW, on the GoldWing the caliper is above the swingarm, just ahead of the shock.

is the gl1000 comstar and gl1100 reverse comstar the same in terms of spacing?

No, the GL1000 wheel fits too far to the left and the final drive sheild has to be removed or the rim machined wider to fit it. It's a lot more work for the GL1000 rims. If you just want a disc brake rear wheel, the easiest way is to go with spokes, and buy a fully assembled spoked wheel and caliper bracket from cognito-moto. Snag a used ducati rear caliper and you're done. It's the easiest, but it's also the most expensive, and it doesn't look period-correct with those modern Warp 9 rims. Pair that with a DOHC CB750K front wheel laced to another warp-9 front rim. The second easiest way is to use reverse comstars from a CB900C (16") or GL1100 (17"). The hardest way is to use a GL1000 rear wheel.
That said, if you have a big lathe and/or know a machinist even the hardest way isn't that hard. But the GL1000 wheel won't even fit properly between the CX500 swingarm without some machining. The brake disc will want to occupy the space where the left shock sits.

New here, been looking at CX500s for a bit, and came across someone local with a bike that supposedly has a GL1100 17" comstar on the back, and the guy mentioned it was a mod.
Given the similarities in the early 80's models (GL1100, CB900C/1000C, and CX), is there any reason a GL1100 or CB900C swingarm couldn't just bolt in directly?

I believe the GL1100 swingarm is quite a bit wider and I'm sure it weighs more too so it would increase the unsprung weight.
