Thanks guys will look at that

Thanks for the replies .after much ado, I have cleaned out the female mt2 using a mt2 finishing reamer and its certainly helped. I think that there had been slight damage at the start of this taper throwing it out ie the centre etc not seating correctly.

I now have it within a thou on the nose.Thanks again for the suggestions

Just spent 2 hrs there with various dti gauges and the mt2 taper is running untrue. Not missed anything there is very little to this lathe.

Thanks for the quick replies.

Maybe the 3mm is exaggerated by myself but it is certainly way excessive on the mt2 internal taper This old lathe runs in split brass bushes and there dossnt seem to be wear or play however i take it on board they may have.

Would it make any difference using a mt2 reamer to clean it up?

I never had any noticeable problems before. It isstrange that the internal bore is seen to be oscillating. 😥

I have recently stripped down to paint etc my old Grayson lathe. Having just built it back up, I have noticed that when i place a dead centre in the spindle bore it oscillates by up to 3mm! There is no burrs and on looking in towards the spindle when running the bore appears to be oscillating which it wasnt doing before. I placed a dti on the nose itself which is showi g a runout of just 1/2 thou albeit when running a chuck its runout is around 4 thou! Is the spindle somehow became slightly bent?

Martin I meant to ask also, did you drill/tap to fit your small oilers? As you can see from

my previous pics mine only has small oil holes and the smallest oil cups I can find have a

1/8 bsp thread? Thanks

Thanks Martin

Thanks for the reply Martin. I did have a thought it was maybe on a small key but ijust couldnt make out if it did or not. Just to clarify it knocks through from the rear towards the front after everything attached to it such as bullwheel has screws removed?

This is the driven gear. It appeara to have a little notch which i assume is to knock it round to thread it off?

Hi

New to the forum, so apologies if this has been posted before. Im presently using an old Grayson which I am in the process of trying to smarten up however I cant seem to get the main spindle out of the casing. This is due to the rear gear (which drives the 2 tumbler gears) being held fast on the shaft. Am I assuming correctly that it screws off just like the collet? I don't want to force it or break any of its teeth? Thanks
