Many thanks everyone – especially Neil.
More info to you all is that I am 83, and the spindle is not just running out of truth but the whole spindle seems to have moved in the housing. I am well aware that this is just about impossible and I suspect that anyone with a bit of engineering knowledge could put it right.
However, as I also am thinking of changing my band-saw and have a never used lever feed for the ML7 tailstock (bought the day before my Tri-lever changed into a Super 7B which also has a rack-feed on tailstock and a Newton-Tesla inverter unit & DRO) I am going to offer them to a local tool dealer and buy a smaller mill from ArcEuro which is belt-driven with variable speed control. For all that I do I think that machine will be ideal.
I can no longer lug heavy engines around so I am enjoying making simple bits and pieces from the mag.
My S7B now cuts metric and BA threads and the DRO makes life simple.
Metric does not frighten me any more.
Once again – many thanks and best wishes to you all on this marvellous site.
Richard.
