Wow he must have been filthy rich Doug..That's over 1.20..

You're pretty good at math, Joe!

Thanks, as long as you do not stick letters in the math questions I do
OK.

I said that he was very wealthy not because of the washers, but
because his house was on 2 blocks of property in a very expensive old-
money inside-the-beltline neighborhood. His house & yard was bigger
than many university properties.


Most likely made the money on his own, and knows the value of work and
being thrifty when needed.

Dimes make great #8 washers and cheaper than SS.

I think you'll find that they have a lot of creep & distort too much
at high loads. However if you don't mind tightening the bolts every
time you sail and replacing the dimes every year or so, they'd be
great.

Depends on the application Doug, attaching 1/4" wood paneling would
be an example where a high load would not be experienced. Nickles
would be best for high loads, once you get above nickle size you need
to switch to washers. BTW if you do not have a gasket for your wear
plate on a Jabsco pump, a dollar bill can be made into a nice strong
long lasting gasket.


Look up the relative strengths/properties of the materials before
making cheapo substitutes.


Sounds like over engineering IMO, some of us could use simple logic
and do not need written proof from some black tie pencil pusher in a
cubical.

I guess that's why there's a demand for real engineers.


Well there are times when they come in handy.
