When I first read about turning square stock in a 3 jaw I doubted it's
safety or even the sanity of such a set up.
None the less I had to try it to see if it would work.
It's just a matter of trapping two side between jaws then shimming the
third jaw to bring the open side to the same run out as the trapped sides.
I this case a small piece of 1/8" steel rod brought it to within .005"
It felt surprisingly solid. Cuts of .050" depth didn't effect it stability at all.
If your 4 jaw is available by all means use it! But, it is possible to get by
with the 3 jaw if the need arrives.
As I've said before, If it doesn't look and feel safe to YOU, don't use it!
