The recent alternator topic had a bracket design made of 4130 angle.
I've trial fitted an alternator (60 amp, 8.5 lbs) to my engine and it
looks like I will need 1.5" angle to weld up into the upper permanent
mounting brackets.  The lower bracket will be a slightly bent arm (not
shown).   I'm having a hard time finding 1/8" 4130 angle in this size.
I can get 304 stainless in 1.5" angle, but it is a lot harder to
machine.  Would mild steel be strong enough for these small, upper
brackets?  Or, does anyone have a resource for 4130 angle in small
quantities?

The pix also show the stock RX-8 belt idler/tensioner roughly sitting
in place.  Obviously, the standard unit will not fit, but it gives me
an idea of what type of idler arrangement might work.   An
idler/tensioner will allow the belt to clear the crank position sensor,and also allow the alternator to be fixed in place.    I'm also not
going to keep the ignitors in their stock position, due to height
issues.

Thanks

Looks good.

.065" or .090" 4130 will work  fine if you
weld washers around the bolt holes. Long story but
it has to do with bolt bearing stress.

BTW Scott that is a cool looking oil pan. Where did that come
from?


Paul Lamar ...No rotor no motor.

The oil pan is a Greddy that came with my engine.  It just happens to
be on the bare engine because I'm drilling oil level sensor holes in
the pan Ed made for me.  When I'm done, I'll put the pan on my RX8
Shinka.
