Subject: powersport accident... exhaust flange.

Everett Hatch came up with this idea about six years ago.
Gives the exhaust tube the ability to move around on the spherical
joint as it heats up and cools down.
I am not sure why Power Sport abandoned it.
With an NC lathe these things can be knocked out likity split.
Power Sport has plenty of NC lathes.
No spring in the world would stand up to the heat so the
four retaining bolts should just be finger tight and safety wired.
A couple of these would be a lot lighter than the big hunking
Racing Beat exhaust flange.

Nice design, but I can see a spit forming between the two pieces where
they clamp and the extension protudes. Just a guess. I would like to see
those tested! Then lets turn them out of stainless on a production
basis!

They will split only if they lock up. Keep them loose.
