I think that we have to thank our Rob and DoubleBoost for reminding me of perhaps the simplest solution. Simply turn a metal dowel to a fairly tight fit in the top of the hollow spindle. Find a suitable bottle cork( Happy Birthday, Rob) and fill the hollow spindle to the top with hydraulic oil( Thanks John- Andy Barton and so on) Insert the cork, follow up with the tight fitting dowel-- and hit it. :hammer: It's boring, it's ancient and despite all the so called expert criticism, it actually works. It is a crude hydraulic jack. |

I remember using this method to remove spigot shaft bearings from morris 1000s :) :) :) We used to pack the bearing with grease put a old first motion shaft in the hole and whack the bugger I would not like to think of the pressure generated but it worked :lol: :lol: :lol: :lol: John |

Yes, John, I did say that the male lot of my family were all blacksmiths. :hammer: Your idea is splendid. If the poor wee soul has been pouring WD-40 and summat called Kroil- whatever that is, down the lot, there will be sweet nothin' left in the ball races. Grease, what a good idea :beer: Re-pack the bearings. Unusual but heigh ho-- I like it. :clap: :clap: :clap: |

Whilst Rome wasn't built in a day, there should be progress with the chuck by now. Don't keep us in suspense :bow: :hammer: |
