First - apologies to all for my badly-phrased message the other day - I'm
offering no excuses, except that I wrote without thinking first.
Second - I was misled by something I read into thinking we were talking
about main or big-end journal diameters - of course you can't use
plasti-gauge to measure end-float. That I do with a dial indicator, just
like everyone else.
Third - I was interested to learn that plasti-gauge is not as accurate as
is claimed. I'll view the stuff with more suspicion from now on.
Finally - a slight difference of terminology. Someone said 'pros' which I
took to mean garage mechanics, and most people on the list use that word to
describe someone who builds performance engines or aircraft engines.
And finally again - When I build competition engines I have the crank
journals ground to a diameter a couple of tenths above the largest book
size, blue them up, and hand scrape the bearings to fit. That's how I was
taught to do it years ago when bearings were mostly solid white metal, and
I still reckon it's the best way.
Bye for now.
