Christmas came early for me this year. I purchased an accusize c5 chuck and also some collets a spin indexer and a square collet holder it took a bit of fettling to get the chuck mounted. When I purchased the lathe back in 1970 I also got a spare back-plate this was only a 4 inch one and the chuck is 5 inch so with a bit of modification to the spare plate and some 20mm clamp nuts I was able to set it up with.0005" run out at 2 inches from the face of the collet. which is ok for what I am doing on mt almost 50 year old lathe.
