Coronet Major - morse taper stuck

[Robbo3]

.......... and demonstrated the limitations of the little pin thingy you get with the AT1628VS to secure the spindle - it kept falling out. ...... !

Sorry, forgot to reply to this.
Measured the locking pin on my AT1628VS & it goes in halfway up the second shoulder. It doesn't fall out when I jiggle the spindle. If yours doesn't go in that far then I would suggest the holes need a good clean out or the pin is oversize.

FYI, a quick blast from the blowtorch enabled me to winkle the bit free. Thanks all for the suggestions.

And a rummage through the box of bits that came with it revealed... a thread protector. Happy days.

On the subject of majors, can anyone tell me how the swivelling head locks in the bowl turning position? There are two holes that align so a in pin drops through for turning between the points, but I can't see a corresponding one at right angles.

Thanks again - awesome forum!

I doesn't need to align with anything unless you have tailstock on a skyhook.

Thanks for the speedy reply, but I don't quite follow. Do you mean for bowl turning, the headstock isn't locked in position? Much obliged.

It locks down just the same as it would with an aligning pin, but you can put it exactly where you want. I often offset mine 10 - 15 degrees not because off the size of the blank but just because it's easier on the back.

Try cooling the 4 pronged Morse taper with ice or a tin of canned air to make the steel contract before applying force to remove it.

I expect he's done it by now.
