That's an interesting challenge!

My first thought was to use a long curved drift through the drawbar hole and hope that it did not 'spring' too much when tapped with a hammer. Ideally you should put some support under the spindle to reduce the chance of bearing damage.

Another idea might be to make some sort of expanding nut that you can insert up the spindle past the top of the sleeve, then use a long bolt and tube to pull the adapter sleeve out. Sounds easy but I bet you will have fun!

Hi Gavin,

Here is one suggestion. Make an oval plate about 6 mm thick with its larger axis just less than the outer diameter of the adaptor sleeve and its smaller axis just less than the hole at the top end of the adaptor sleeve. Drill a small hole in its centre. Now thread a piece of string or wire down through the spindle. tie the plate on the end of the string. Hold the plate so the larger axis is vertical and pull it up through the sleeve. When it comes out the top of the sleeve it will hopfully drop across the top of the sleeve. You should then be able to drop a bar from the top to tap it out. I suggest squirting penetrating oil down the spindle a day or so before you try this. Heating the bottom of the spindle with a hot air paint stripper may also help. A variation on this idea is to tap the hole in the plate and try to screw a threaded rod into it from the bottom to draw the sleeve out. I have one of these sleeves so I will measure it tomorrow.

If you can attach an old but servicable 8-10mm drill securely to the 2mt tang then do some (careful) work with it.

Drill a reasonably deep hole in a lump of scrap, then lifting the drill slightly and moving the drill slightly from side to side like it was a slot drill the vibration will probbly free mt2 taper from the mt3 taper

That sort of thing, the main thing is that the tooltip is (slightly and carefully)unsupported and you induce tool vibration(asking the machine to do too much work) on an unsupported tool tip

The tooltip only needs to be a fraction above its pressure point, and as the morse taper releases the mt2 will spin inside the mt3 taper

I've found that morse tapers are totally useless once they get a bit of work vibration and have no supporting pressure on the tip of the tool.

The morse taper loosens up, no matter how tightly it's been fitted.

….unless of course…he's superglued it in…lol

Hi

If the 3MT /2MT sleeve protrudes below the end of the spindle a little you could turn a blank disc the diameter of the MT sleeve, weld it to the end of the MT sleeve, then drop a bar down the spindle bore and tap it out.

Or

Turn a piece of bar to 2MT and loctite it into the sleeve, place a bar down the spindle bore and tap it out.
