Andy,
The three jaw sure runs true. I've never used a lathe with a threaded spindle so maybe should not comment. The indexing portion behind the threads appears to be straight rather than tapered, anything mounting to that is going to need to be a very tight fit or you'll have run out. Measure the bore on your three jaw and compare it to the collet adaptor. I suspect the collet adaptor is bored oversize.

Free advice is worth exactly what you payed for it.
