Darren:
Thanks for all the support guys, much appreciated. So much I'm going to inflict you all with even more pictures :)

Turning my attention towards the drive set-up I have this to work with

Seeing the need to strip it down and having to re-arainge the order of components I did just that.
Gave the monster 1.25" shaft a bit of a spin in the S&B whilst abusing it with some sanding paper, came up quite well.

Here are all the components in bits ready for a clean

It all came apart quite easily once it'd taken some of the burs of the end of the shaft where it had been knocked.

I have some ideas on how to set all this up, inc having some method to enable loosening of the flat belt for changing speed purposes.
But if anyone can provide some pictures/drawings or ideas of how it's all arainged it sure would be helpful.

Darren,

Normally with a flat leather belting drive using a curved cone as you have, tension slackening isn't normally used. Just slip the belts across by hand. The leather belt finds its own centre on the top of the curved cone pullies. Just make sure the cones are perfectly in line and parallel to each other.

All you need to do is check that both sets of cones are a matched pair and the same size.

If you do want to put a tensioner on there, use the sliding feet of the layshaft as the tension agent, but you should find with a leather belt, even if it is slack it will still give a very positive drive.

You can easily double the range of speeds on the lathe by fitting a double pulley on the layshaft and motor, and tension the motor belt by sliding the motor on its mounting foot. But I wouldn't get the lathe running at any more than about 1500 RPM because it only has phos bronze bearings, and above that, they are liable to get rather hot.
