I think the max rpm with the motor I have and reductions from the layshaft gearing will be aprox 800 - 900rpm. I hope to have the lathe powered within the next week so we'll see how things go.
Nothing is surprising me on this lathe now.
I have doubts that the tapers in the head & tail stock are Morse Tapers and could be another less common type. Neither a 2 or 3mt will fit in the tailstock, looks like a 2mt may fit if I remove the tang but will see after I've drilled the through hole as the tang may just need clearence.
I got my first dial indicator the other day and checked the runout on the chuck and was very pleased to see 0.02mm on the chuck body but 0.4mm on a 12mm ground silver steel bar in the jaws, guess they'll need grinding!
Just seen a video by our John (Doubleboost) on grinding chuck jaws so at least I now have an idea how to proceed correcting that.
