Clint (oldschoolace), Andy (rooski), Steve (animal), and Spen (spen69) might be able to help you out. Sorry if i've forgotten any of the other usual suspects

The best and most effective way is to go to a hardware shop and buy a replacement big bolt thats undrilled. take the old one out and screw the new one in a few threads, then hit it bloody hard and the shaft will come out. you can sit the stem on a couple of blocks of wood and let the shaft hang free below. DON'T use a vice to sit the stem on while you wack it, the vice is steel and will leave marks all along the underside of the stem, even if you use alloy soft jaws, you will still potentially mark the underside of the stem. I know, ive done it!!!!

and  - that's how it's done

[Picklez]

Or:

Remove stem bolt and wedge
Loosen Large bolt a good few turns
Put stem in hot oven for 5 - 10 minutes
With oven gloves (or similar) remove stem from oven and carry to work area. Support stem between two blocks of wood (as Jaymz described - with all of his warnings regards not using a vice etc) and tap top of large bolt lightly with stiff rubber (or composite) mallet.
Job done 

Re-fitting is kind of inverse. Freeze shaft, warm alloy head. easily fit back together, tighten bolt, and allow to cool.

Principle is: head is alloy, shaft is steel, alloy has higher thermal expansion coefficient than steel - expands more than the steel for a given heat change.

I've done it a few times, has always worked a treat, and i don't end up destroying anything belting my beloved stem to death with a hammer. Also i use one piece of wood, a short length (download your RAD Thesaurus for translation of that one  ) of 4x2 with a 7/8th's hole drilled in it.

Hope it helps, if not hope the info's good for some others.

Has anyone done similar with a suntour stem?

I know they don't have a bolt like tuff neck so does that make it more difficult/impossible?

I don't think you can remove a shaft from a Suntour stem!

I've never seen one removed either.

I've removed shafts from interference fitted stems before, question is why do you need to?

[jonnydiezel]

was thinking if it was possible have a silver one annodised to blue?
but understood that with the steel shaft attached it probably wouldn't work

[oldschoolace]

I imagine there would be a way to annodise it with the shaft in. You can't anno steel so it may just be a case of doing the lot. Either that or some sort of masking fluid/tape

This can and has been done by CCA and Chameleon successfully who masked off the the shaft using tape.

Will make an awful mess of the shaft if it's not done properly though, seen one that hadn't been done properly and the shaft was corroded to fook.
