Listerati,
I=92m working on the Spitfire=92s traverse leaf swing spring rear =
suspension and can=92t find locally the 7/16=94 fine thread (20 tpi) by =
3 1/2=94 bolts that were holding the vertical link and to the trunnions =
and to the swing spring bushings.
I can find the right sizes in a coarse thread (12 tpi) grade 8 bolt and =
thats my plan. The old ones are grade 5 or in one case a bolt with no =
slash marks on top. I don=92t know what it is.
=20
Do these bolts need to be fine thread for any particular reason, e.g. =
for safety, torque specs, etc.? Is a grade 8 bolt a good idea where it =
will be stressed with all the up and down motion with the vertical link? =
Too brittle? Usually I go for grade 8 whenever possible but I=92ve heard =
there are instances where it might not be the best solution.
An aside for Thanksgiving:=20
My son and his wife teaching in Shanghai said the Chinese love to =
celebrate American holidays (they know them from American TV and movies) =
but their take on Thanksgiving is that you thank people who do nice =
things for you. So they got cards from their students thanking them for =
teaching. Kind of a different twist but a good one I thought.
Happy Thanksgiving to all.
