[DML] Re: Torsion Bar Issue

[tobyp@xxxxxxxxxxxx]

Brandon - As Bruce Benson noted in another response, this will not 
work.  Welding any metal changes the characteristics of the metal 
dramatically.  The torsion bar starts as 304 CRES, which is not heat-
treatable.  That's why it was cryogenically tempered to create 
the "memory effect" that allows it to be used as a spring.  (You 
should see how much mathematics and calculus is involved in 
determining the exact nature of the cryogenic treatment ... 
unbelievable!)  Welding will disrupt the molecular and crystalline 
structure of the CRES.  If you install this bar into your car, it 
will break at the boundary between the weld filler material and the 
base bar material.  This is where the materials are all mixed 
together into a sort of "steel stew", with totally unknown 
properties.  As Bruce noted, the right hand bars are available.  In 
fact, we have one in stock at very good price.
