Vance,That might be the case with Ti but lets be realistic if the Ti

stud is not

compromised during installation is notch sensitivity still a concern?

Does the

flexing of housings in our installation cause notching? Would exceeding

the COE

cause it? I will test it but  I think it wont. just my 2 cents worth. On

the other

hand the point that Paul brought up about housings and shrinkage is a

major

concern, but then again if my engine is overheated in flight, that is

the least of

my problems at that point. I would be looking for a prime piece of

realestate.

Doug

I think he is referring to the root of the thread. That is where the steel

studs

break when they vibrate.

Paul Lamar

Yes - the thread is the primary concern. Rolled threads as used on virtually
all steel bolts are
MUCH superior to machined threads (If the Ti threads are machined I would
not touch them
with the provrbial 3.048 meter pole) The tensile strength to weight of equiv
Ti and ferrous
alloys are virtually the same - if you want more elastic stretch, neck the
steel, and the threads
become even less of an issue - or use Bellvilles - Vance
