Hi Richard, Good video! As John S said, it's just removing metal with cutting tools and any arrangement of work and tool that gives the required results is fine. In fact I can see that for some jobs it would be a lot easier to turn in the mill rather than the lathe.
 
Regards, Hugh

Very nice video, I am quite impressed by how easy it was to part off  presumably by the look of the piece of metal that you turned you have also done some knurling?  Where did you get the laser pointing tool? was it expensive?  It looked quite handy

regards David

Thanks David for your comments.
 
The knurling was already present on the piece of scrap i was using. I'd like to try knurling, but with a  non-CNC machine can see i'll be restricted to knurling for the width only of the rollers. Also, I'd use a pinch roller not a single side roller.
 
The laser finder is from http://www.lasercenteredgefinder.com/ - they are available from Chronos too, but I ordered from US to get a 10mm vs. a 1/2" shank. HAving said that, with 1mm 'range' collets either will clearly do.
 
There are two point (no pun intended...) to watch for:
1. Battery consumption - heavy. I see from their website that they now do mains powered ones! 
2. The size of the dot is surprisingly large, and you need to throttle it right back with the supplied polariser filter. My learning here is to do just that and then pop on my binocular viewer to get it spot on. So, is it 'better' than a mechanical edge finder: probably not, but with practice it's at least AS accurate, it's quicker and avoids the arithmetic.
