I was looking through a hot rod type magazine and noticed that there are a
lot of different companies building crossmembers with Mustang II type
suspensions for a variety of applications. Has anybody ever checked into
having one of these companies build a crossmember for the Tiger using the
Mustang II components.
Thanks,
Joe Brown

Ok, once more, with reason. My apologies to the list, but I can't let this
go quite yet.

An absolutely indisputable (and alarmist) statement. Using the same logic,
I'll go you one better. Every pin will fail using rubber bushings!!! If it
isn't from metal fatigue in the year 2035, it'll be from complete conversion
to ferric oxide in 2265.
Can we agree on the following perspective? All pins will eventually come to
the end of their service life. All those variables that you mentioned --
bad Ackermann, today's wider, stickier tires, alloys that are more brittle,
and bushings that transmit more shock will shorten that service life.
Can we also agree that by increasing the diameter of the pin by 78% (my
simplistic measurement) through the critical area and using a modern, more
flexible alloy (my judgment), that we can extend the service life, and
extend it further yet if the Ackermann issue were addressed at the same
time? I think so. Even enough to use Delrin bushings, in my judgment.
Everyone should use their own.
I will also gladly accept the results of a failure analysis of one of Dale's
pins. Unfortunately, we don't have that option, given that I know of no
failures in this pin, even though it's been in service since at least 1989,
along with the Delrin bushings designed to be used with it.
However, you haven't said that your expert has evaluated this pin -- perhaps
he's never even seen one. If this is the case, then Dale's pins are beyond
the range of "as far as he [your expert] could tell", and your comments
need to be explicitly confined to the OEM-design pin and its varied material
compositions.
Dave, I realize that you're doing the Tiger community a service by having
the failures in OEM pins analyzed. Thank you. I just worry that we're doing
a disservice to someone who has also done the Tiger community many a good
turn by casting the net too wide on this issue.
Dale A., my apologies if I'm doing something that I shouldn't -- just e-mail
me with the words "shut up" in the subject line, and I'll be automatically
removed from the list thread :-)
Brian
