[DML] Re: PDC's Redesigned Trailing Arm Attachment

[tobyp@xxxxxxxxxxxx]

Bill and List - Yes, I have studied the PDC design, and it is much 
more robust, as you suggest.  The key with his design is to load up 
the bolt in double shear, which means that both ends are supported, 
and the load is applied in the middle.  This essentially doubles the 
amount of load that can be carried for a given amount of bending 
stress.  Or, put another way, for a given load, it cuts the bending 
stresses in half.  (Note to you purists out there - the numbers 
actually vary a little from that, but I'm talking in round figures 
here) There are a couple of design details that I would do a little 
differently that Pearce, based on my experience with high-
performance jet aircraft structural design, but his configuration is 
much better than the stock DeLorean.  Tell me ... what is the 
perceived demand for a retrofit kit to convert the average DeLorean 
to a similar more robust design, without changing the entire frame?  
This can be done, but it would be quite a bit more expensive than 
simply replacing the bolts.  That was the main reason that I went 
that way ... to make some kind of solution practical to the typical 
DeLorean owner.  I would be interested in getting some feedback on 
that question.  Keep the shiny side up!
