requirements are minimal. The most strain on it would be when it falls
vertically through the vise screw and is stopped by the screw, the
worst outcome is that it will hurt my foot.

So. Is there some way to weld it that would not crack and would hold up?

If the rod end is planar, I'd TIG it. Easy weld. If the rod end can
be made concave on the lathe, cone would do, then I'd silver-braze it.
The silver-brazed joint would be about invisible and have more than
ample strength.

Thank you Don.

I welded it with 410 stainless filler that I had, the choice of filler
was made "because I had it". I posted a link to pictures separately.

Isnt it amazing how much work gets done, even after the plans have
been changed to reflect "whats on hand"?

all work is done with what is on hand when you think about it. :-)

That's how i get things done. Very small shop and very far from a metal
supplier. Boss says "make a few of these", so I draw it up. Then, i
re-design it a few times to reflect materials available and tooling.
Sometimes it takes longer to get ready to make it than actual machining
time.
If I absolutely have to have metal ordered it could be 2 weeks to 2 months
before i see it.

Hey People,

Concerning this "Attaching a Bearing to Mild Steel" thread.... does
anyone have any good suggestions for tools that can be made or tools
that can be bought so that a person could HOLD these ODD types of
metal together WHILE using both hands to BRAZE with ? I seem to be
having a difficult time "CREATING" or "FINDING" decent Clamps or
'third hands' that can hold "AWKWARD" objects firmly in place. Any
suggestions on how to HOLD items firmly together such as the Bearing
and Rods or SIMILAR 'weird shaped' steel objects would be greatly
appreciated !

Cheers,

/FC....
