Lincoln? my nephew parents live there. Perhaps when the situation normalise , and we be able to travel I may go to visit him, and try to contact Roy , to see what is de difference , and appreciate his skills levels..

I dont like the Myford m42.5x2 spindle thread (I realise that it maybe there together with the grove in the location diameter, to try to stop the chucks from being unscrewed , but in my opinion they should have used a better and more modern way of chuck location

stay safe

Thanks Andrew, Like I say I have never seen any close up pictures os a Super7 with a big bore, At the moment , after purchasing a Super7 headstock for replacement of my Spindle and bearings damaged ML7 , the Idea is to start up with the old ml7 headstock , making a spindle and bearings similar in shape as the Super7 , with the hole now being about 17? mm , I intend to make it at least 20.5 , and for that I will need to line bore , the existing bearing locations, and yes , maybe alter the geometry of the tumbler..

I have a fully equipped workshop including a Colchester Student 1800, Bridgeport knee mill, and universal T&C…

Why do I bother with making a big bore Mod in a Myford , when I have a 38mm Colchester? , well , I think that it’s the challenge,

sorry for the rant

Hi; can someone please point me to were I can see pictures of Roy's big bore conversion? I would like to do it as well, but first because Im intending to make the new spindle (4340 nitrided) and with a different taper, I would like to see if I would have to make gears as well..

Regards
