4 Jaw Chuck Advice Please.

Good afternoon. This is a first for me, asking for opinion on here regarding a product. I wonder if I can ask for peoples experiences with a San Ou Independent 4 Jaw Chuck.

I am debating buying a San Ou K72 800dia independent 4 jaw chuck. I have a D1-3 backing plate to mount it on.

I am more than able to use my lathe etc but I have never bought a San Ou chuck and wondered if anybody on here has one and what its quality is like, hence my request.

In an ideal world I would simply buy a D1-3 4 jaw chuck, but they are not commonplace and I want to get on with a specific job which requires such a chuck..............unless somebody has a 200mm D1-3 independent 4 jaw chuck at a good price. I can for instance get such a chuck for sub £90 on the bay and delivery is 2-3 days, all of which sounds like a bargain.

Thanks in advance.

I bought one of their little 100mm independents, and it is better than the original on my 7 X 12 lathe, it is not in the Pratt Burnerd or Bison league. It is, however, much better value for money.

You might find it comes with only rear mounting near the periphery and being a four jaw, you could easily make it front mounting if required.

Vertex chucks might be within your price range, worth a look.
