Stuck Collet Chuck Arbor
Fergus OMore:
No, my friend, no! I'm still the boy who came from nowhere with no education in a war torn Britain and who left school at the age of 14.
I'm the peasant boy who grew spinach and sold it in the local market to have a few pennies when my father was injured and we had no money.
Today, things have changed but you asked for help- and I gave it.

well, 1- this weekend, ask my kind wife to give me a hand to take the head down and apart to take it to Press shop, or
2- I'll just lay a piece of plywood to back of my Q7 to take the whole thing down the industrial park, or
3- still should be on guaranty.. package and send it back to factory to serviced (that means, at least next 6 Months I will be filing my fingernails..)
I know I'll be always thinking only thing left that, I havent tried, about the Hydrolics solution ,shoul I know only how to do it...?
but, by all means, dont want to cause new frustrations
regards,
Unal

the hydro method will not work with a mt2/3 quill because it will have a drift slot in it to extract the mT drill bits , big hole in quill nada hydro pressure , unless this is a R8 which i doubt looking at the pics
as I have said before clout it use stilldrillin method to take the load ( wood is no good it will absorb the blow ) its got to be solid with a quick sharp impact
all this will be of no consequence if the said shank has turned in the quill then we are in a different ball park it could be galled or evan friction welded in
but as a rider if you are more comfortable to take it to a press hop then by all means do so , should have enough room in the Q7

Hi Unal,
When I started at my current job the same problem - milling cutter chuck had been stuck in the spindle for about 10 years (the previous 2 engineers had been there that long...) - I ended up making a pair of wedge forks, one bearing against the end of the spindle (with some pieces of flat to take up the inevitable gap), other against the back of the chuck, then pulling them together with 12mm bolts through two pieces of 20x0mm bar - made the wedge angle quite small (5 degrees?) and greased the contact area, took some force on the spanners, but then there was a Big Bang! and the chuck dropped out of the taper! Ordinary mild steel would be fine for all except the bolts and nuts, which should be fairly good quality high-tensile...
Apalling Crap-O-CAD:
Might be worth a try?

1. Lock the quill- and I mean LOCK it
2. Drop the spindle/chuck down to the vice
3. lock it to the vice
4. take a metre long scaffolding pipe onto one of the arms of the windlass
and
5. PULL
Oh, brother something will move. I promise, SOMETHING WILL MOVE.

Thanks, Mr. Fergus,
I will try this when everything else fails.
by the way, this remid me of;
The guy had a sick camel, and he would refuse to walk… guy had to call the vet. Vet arrived, examined the camel for a while, and asked the owner to bring couple of stools. When he got to stools, he put them behind the camel, opened up his doctors’ handbag and took out couple of fire-place bricks. He got on the stools one foot on each stool and stood up so he could reach up high behind the camel. Spread the camel’s legs apart, reach out and pull camel’s balls behind its legs, as balls to be exposed. He than took the bricks one in each hand… weighed a little, that open up his arms each side.. Than WHAAAM..! Smash hit the camels balls between the bricks.. WOW! The camel took off its eyeballs out, running like crazy… The owner in fry..! Asked to vet.. “Jesus..! Doesn’t this hurt???”.! “No”, said the vet, looking at his hands holding the bricks, “Not, if you keep your fingers off between the bricks, when you hit it…”
kind regards,
Unal
