[DML] Re: Checked my TABs.... AARG!!

["Toby Peterson" <tobyp@xxxxxxxxxxxx>]

Rob, David, et al - I actually have a design sorted out that 
eliminates all "out-of-plane" bending loads induced by the unusual 
travel that David mentioned in his post.  So many projects, so little 
time.  You would still get the bending loads caused by the 
application of "thrust" through the joint in single shear, but the 
other bending loads would be gone.  The design is such that it can be 
retrofitted into a stock frame, unlike the Pearce Design concept.  
That design is quite elegant, but is compatible only with the new 
frame design.  Your points about the hardened washers are very true.  
I actually looked at obtaining hardened washers when we first 
introduced the TOBY-TAB's, but the cost was very high.  The education 
process relating to the cost of the 248 KSI Inconel bolts has been 
bad enough.  Trying to explain expensive flat washers was just too 
much of a stretch.  Rob - let's compare notes "off-line" and see what 
might be possible.  Thank you to Rob and David for all of your 
contributions to our little silver cars.

trailing arms (ala Pierce Design but stock frame compatible)and be 
rather cost prohibitive. I think an incremental approach by double-
nut retention, stronger bolts, washers, and perhaps even bushings 
(also expensive) would suffice. The first three items combined with 
careful installation and torqueing would eliminate the vast majority 
of failures at a much more reasonable cost compared to custom
