<p>Since I have a spinal problem and now one worn out stiff knee,
getting up and down under anything is a problem. Once I get down
I have to either make do with what I have or haul all 300 lbs of
myself up and get what I need then when I get within a foot of the
floor, I usually just try to fall on something soft!!!!!! I have

This simply isn't an argument against the metric system.

Well the rest of the world for a long time
was British or used British technology<br>
before Sellars came along with his 60º
thread form in the US. The US wasn't a great
exporter<br>
at the time, focusing more on internal
expansion & self-sufficiency<br>

I think there is a slight time frame
difference in our work experience,<br>
My experience with Cat, IH, & AC was in
the 60s & 70 and included <br>
machinery built in the 50s. Cat & IH did
insist on bearings that were <br>
only Cat & IH inclusive, whereas AC
crawlers that used more Timken style<br>
bearings, could be sourced from any bearing
supply co. Five times cheaper<br>
than Cat Or IH equivalents.<br>
An interesting aside was that, rarely was
there a need for machining with<br>
AC, Cat or, IH as regards remedial repair of
parts. Good designs leave little<br>
room for improvement.<br>

Around here, its fruit and meat processing.
<br>
At the local Heinz cannery, all the peach
& pear lines were American sourced,<br>
and the makers delighted in shaft sizes like
1-7/16", 1-9/16" & 1-15/16"<br>
with ODs to match. Only source was the
manufacturer.<br>
Another delight was the spaghetti extruder,
it had a 50hp motor driving <br>
the extruder through reduction gears, every
every shaft was a nominal size +<br>
a 1/16" Guess where the bearings had to come
from. It had one bad design <br>
fault in that the heaviest reduction had no
hunting teeth, and it had some<br>
very bad wear patterns revealed on
dismantling, had a blank forged in
Australia,<br>
it was about 600mm with a 152mm face. :-)<br>

"Plate glass stomach"? <br>
Don't know that saying, although I have
modified modified maker's efforts<br>
for the better, when their designs were
found wanting. Flattering when they<br>
come up with the same improvement...<br>
