[TheForge] Upsetting the middle of a bar

[Bruce Freeman]

Actually, though, that's exactly the technique I suggested.  The
difference is that with a tire you have no choice but to "bite" the
metal.  With a picket you can simply block the ends.

The problem with most tire shrinkers I have seen are they but very
nasty
bite marks in the steel outside of the upset.  This was fine in a tire
as it was on the inside hidden by the wooden wheel but would be very
unsightly in a picket.

I've got several tire shrinkers that would probably do this but I have
yet 
to try any of them.  The one that would probably have worked great is
a
Star 
tire upsetter/axel welder.  This was used to weld stub axels to the
main

axel.  It has two tables with dogs that lock the stock in place with
the

heated section in-between.  Then with what looks like a ship's wheel
that 
you turn, you compress the two tables together.  I still have not got
this 
machine fully freed up and working.
