Head set cup removal probs. HELPPPPPPP

[dordymush]

Right just gone to put my head set in my 96 Holmes and the head set is too deep for the head tube.
Trouble I got is its a machined head tube and the cups are flush on the inside so I got nothing to hit against to knock it back out.
Is there any trick to doing this. My oversized dirtbike is the same and I need to get that out too.
Any help would be good before I smash the lot up lol.

Is it completely flush inside?
I have a removal tool rather than a hammer and screwdriver.
I take it you don't want to damage the headset.

woodwork vice on the headset then twist the frame off. Or maybe one of those rubber strap jam jar openers old peeps use may help

 Being flush on the inside could be a problem  If it were mine I would tap around the external of the cup with a piece of nylon or acetal bar tapping it with a hammer at the other end, if you pop into an engineering shop they may have a bin with a small off cut in it.
Too get the standard old school steel cups out I use an solid piece of aluminium bar from the inside of the tube, being mid school your cups are probably alloy so you need to tap them out with a material softer than the cups so as not to damage them.

99.9% mid-school headsets = steel (or heavier metal) 

Done em before Dave using a piece of flat dowel/missuses wooden spoon cut on the handle end to flat.

Stick the wooden dowl on the bulge out of the headset on the outside of the headtube and twat the other end of the dowel with a hammer. Repeat around the cup. Knocks the cups down enough so either you can keep smacking em out that way or then pop em out the trad way from the inside

Here's an expertly drawn tech diagram of what to do Dave - guaranteed not to distort your headset:

, I don't know what their made of , i'm still back in 1979 
If the cups are the same shape as the one in the picture, I can see why they need replacing

Bits of scaffold mainly

If you go the dannywhackit way I suggest some tape around the head tube to give a it more protection.
Anyway I thought you would just use your teeth on it like opening a bottle

[rooski]

Get a piece of scaffold pipe,cut it in half so your left with a semi circular piece.

Get a piece aluminium can (soft)and shape it round the end 

Sit the ally clad end on the outside of the cup

twat the other end with a hammer.

Top man Danny mate.
Done the job spot on with a bit of wood.
Never thought to look how deep the head set cups were before.
This was way out when I looked after.
Ended up knocking a primo one in and that's done the job.
Ya learn something every day lol.
