Hi List,
Two years on from this e-mail 'thread' (could be a chain?) and I've just
junked another useless trunnion bolt that cost me #5 from one of the usual
suspects. I've junked so many now - all new ones not original ones I could
have bought the titanium bolt and still been quids in.
So with a cost likely to be between #25 and #30 EACH bolt + shipping I'm
going to have a very small batch made. From what I remember from the last
time I got quotes for this it needed about 4 times as many bolts as there was
interest for to get the price any lower.
For simplicity I'm only going to have the bolts made in the superior grade
of stainless (not the choice of 2 grades there was originally) and titanium
which only worked out something like #4 or so more than the stainless.
I'm undecided on the split pin hole as it added about #2+ to the price. I do
intend for the wrenching head to be 12 point and probably 7/16 wrenching
like the ARP stainless stuff is.
So e-mail if you are very interested now, specifying stainless or titanium
and how many bolts you want and eventually I'll get back to you.
Regards

Hi List, there has been some interest in this but not yet enough for an
economic batch. I've checked the material specs and they exceed class 8.8
and certainly exceed the stuff currently available. I'll be getting an
original bolt for testing soon.
So any more takers for these stainless steel bolts or even Ti ?
Regards
Daniel

Hi List,
Don't know about your side of the pond but in the UK the trunnion bolt's
Iv'e been able to buy are inferior to the original bolts. I've usually
discovered this after stripping the thread with a calibrated torque
wrench
on
the correct size socket.
I've been in contact with a bolt manufacture who can make a similar bolt
in
a high grade of stainless steel. The idea being they won't corrode into
the metalastik bushings and thus have to be hammered and destroyed.
All you engineer types can be supplied with details of the different
grades
of stainless steel on offer if you want. However, I'm confident the
stainless bolt will be far stronger in every respect than the current
offering
from the usual suspects. I also plan to get an original bolt, even a
damaged one so that it can be tested in comparasion to the current
offering
and
the stainless bolt.
What I need to know is what the level of interest is for this by number of
bolts so I can get a feel for the volume and thus price. I also need to
know if you'd be willing to pay an extra #1 for the superior grade of
stainless and whether you want to probably save #2 by not having the
hole
for
the
split pin on account of using a nylock rather than castellated nut.
Final
price will be more than what I've been paying over here (I think I paid
#6+
a bolt.
