Title: Holding square stock in a three jaw chuck
Post by: macbrat on February 03, 2014, 12:21:39 PM

I know this topic has had various solutions posted in the past. My method for turning between centres, which I haven't seen covered to date, is:- Use an appropriate socket from a standard socket spanner set. They need to be the type that has 12 splines (designed to accommodate hex and square nuts/bolts). These usually cover sizes up to about an inch or so square. This will of course require a centre bit hole drilling in the tail stock end. Hope this tip helps.

Would you like to put a few lines about yourself, in the Introductions Section?

For rough-holding of square stock in a 3-jaw chuck I use a split collar. I turn a collar from scap ally of which the ID is the same as the square's diagonal distance, wall thickness 3-4mm, then I cut a 2-3mm slit in it and slide it over the square stock. All you have to do is make sure you don't grip the split bit right on the jaw.

I'm with everyone else on the split collar.  I make them up as I go and then put them in a drawer for next time I need one close to that size.
