Thanks for the replies - this is great! Robin - I do have a tailstock which is on the other half of the split bed, includes adjustment and centre, my interest in the faceplate was to have a go at a small bowl as a trial piece so I guess I need to get the diameter of the thread as was suggested. Thanks for the tips too, it is 40+ years since I last used a wood lathe!

GeorgeD - thanks too - I will peruse the forum further with interest.
