About screw centers

W.C. Turner
>Hi,

I may have discovered why the screw ctr. twisted in my VM120. In Raffan's Turning Bowls book, he says the screw's that come with commercial chucks, are fine for small blanks up to 6".

The blank I tried my screw in was larger than 6", & probably didn't tighten enough, & I also made the mistake of not using the tail center for support.

Raffan also mentions that he uses(at least in this book)the Glaser screw chuck. I just can't justify $130 or more for a "screw". (no pun intended)

Thanks,
W.C
