I put a 5" from little machine shop. It is many times heavier than the 3" 4 jaw and 3 jaw chucks I have. my cumins came with the face plate. can also get a 6 inch on it but it would not take extending out the jaws much to hit the ways. john
The 4 jaw with a backing plate if I recall is around $90.00 plus shipping.Go to their website and you can get the exact price including shipping.

I have a nearly new 4 jaw, only used for one project. Traded the lathe but still have the four jaw. I may have a face plate as well. Let me know if interested.
