Welcome to FWW. Mike when I started I went with the Grizzly H6265 which is a 1" X 8 tpi. It is on page 132 for $99.95. I have 3 of them now. 2 are 1" X 8 and the other is 1 1/4" X 8. They are excellent chucks for the money and the jaws for a Vicmarc 100 will fit it. I haven't had any problems at all and 2 of them are 2 yrs old.

To succeed in life, you need three things: a wishbone, a backbone and a funnybone.
