    Feels fine - screws in ok. Going to try some solid rods tomorrow - one just big enough to fit down the screw hole.

    Of course there is another solution - anyone got a full set of collets?

    That thing's never been beaten.... Probably the best thing I've come up with on my own!

    One silly question - doubt it but would it be easier to remove if i took the cutter out of the chuck first?

    If it's a morse taper spindle it should also have a slot visible when the spindle is lowered for drifting out mt drills, same should work for a chuck once the drawbar is removed.

    I don't think it will. The drills have a flat tang which extends into the slot. A chuck, being retained by a drawbar does not have this feature.

    Stick a fly cutter in the collet and take a few passes along a chunk of hot-rolled bar. That oughta knock it loose.

    If it's a Morse and it's been in a long time especially if it was put in wet with coolant I could be a challenge to get it out the bar idea through the drawbar hole is still the best idea I would try the freeze spray I use the plumbers type my friend and I used a mixture of heat and freeze spray and penetrating oilvto remove a spark plug from a landy that was seized in oh and a 4ft breaker bar

    Well thanks everyone for your wiring help. Powered it up for the first time today and it runs perfectly!
    Damn chuck still totally stuck though - freezing didn't work.
    Looks like it will have to be Dave's method!

    This is not really a good idea, but when needs must........

    Can you put a piece of bar or something in the chuck to bolt a chain to? Loop chain around knee of machine and wind down the knee to put some weight on the chuck. Then hit the drawbar as described above.

    Disclaimer -I know it will not do the bearings any good, and dont put too much weight on it so you break the head casting, etc, but some times you need a bit of preload......

    I loved Dave's idea so looked for Morse taper removal wedges. Nobody sells them. They DO sell them for Jacobs tapers though. Closest is a J3. A tiny bit of grinding with my power file and they fit.

    How does this look?

    Thinking of using my Record bench vice to squeeze together? 20181004_204553.jpg

    Went to try that - too close to the casting and very hard to hit both at the same time!

    I suppose I could hit each side alternately - after all the bearings are designed to take side loads.

    Tried that as well - a G clamp just isn't powerful enough and very hard to keep straight.
    Really speaking I should make some simple bar clamps like Dave suggested but never having time and lacking suitable bolts I will try and lift the 50kg or so Record onto the milling table!

    Hold a lump hammer against one of the wedges and hit the other with a normal hammer.

    My loving little taps didn't do a lot!
    So close to the casting as well.
    I also tried my new 5" machine vice from RDG tools - could only get 1/2 the wedge on the side of the jaw. Not ideal and was taking some serious force.
