Malcolm,
I only had to turn a pulley for the crank. I was lucky enough to have a pulley
from a mid '70s Buick just laying around that fit the water pump perfectly,
and matched the alternator pulley. I am also lucky, in that I have a friend,
also retired, with a machine shop, so I drew up the dimensions, and we turned
it on his lathe out of steel. We make a regular run to a specialised junk yard
(industrial scrap), just to see what we can find that will prove invaluable
later on (ie, JUNK!). We found a piece of steel bar 7" in diameter, by 4"
long. Since then, we have found a piece of aluminum of about the same
dimension, and I am toying with the idea of making another pulley out of it.
The lighter the pulley, the better.
I would think you could find a perfect match for your alternator at an
automotive junk yard, If you can find one that will let you look around.
Insurance regulations have pretty much put an end to that in some areas.
PS: I also have a big honkin' GM alternator on my TR6. Sit at idle, all
electrical accessories on, and no red light. With EVERYTHING on, driving
lights, hi-beams, heater fan on high, radio blasting, the voltage drops to
around 13 volts. at 1500 rpm, 14.6 volts.
