Airlite hubs restore

Hi,
I scored a set of Airlite track hubs that I'm wanting to tidy up before re-building. They're a little banged up but spin ok, infact the front has been re-packed and is super smooth.
I was wanting strip them down including separating the flanges to have them re-anodized red and the centres re-chromed. I don't think disamantling them should be to difficult. Has anyone done this before? Any advice?
Once that's done, I'll have someone (with skills..) put them back together. To have someone do the full job is way too expensive.

Also, what's the best way to remove the cog from the shell?

Thanks

Hot water to help get the flanges apart and together.

Lace up the rear hub, remove the cog, de-build the wheel...

I worked out that a few sticks of dowel fit in the holes of the flange. With them in a vice and the hub on the other end there was just enough leverage to loosen the cog with a chain whip. So, no need to build the wheel up again

However getting the flanges off is proofing a little more difficult. I soaked them in boiling hot water as you suggested to hopefully loosen them up but.. no good, can't seem to get em loose. I don't want to be to ruff with them just in case I bend the centres..

Anyone else got any suggestions? Is there something I could spray in them with? Or a more heavy duty solution I could soak them in without damaging which might loosen them up??

Cheers

The flanges are press-fit and have to be removed the same way. Upping the temperature loosens them a bit but they are still press-fit. Be careful how you remove them, support the flanges close to the centre.

An hour or so searchin on line and I found the perfect tool for removing the flanges.. a "gear puller".

You can get a cheap one for around AU$20 that should do the job or.... ask a mate if you can borrow his. His "Toledo" puller I used was totaly configurable to fit.

A small spray of "Loctite freeze & release" inside and out around the flange and barrel, and a small hex head screw that fit perfectly inside the barrel (of the hub) for the gear puller's pin to push against, and they came off no trouble!

Flanges off to be anodized next week!

A few pics below for anyone thinking of doing the same.

klook's last post here was January last year, so I wouldn't hold my breath.
