Re: ATM Advice on Large Spherical Mirror?

["Vladimir Galogaza" <vladimir.galogaza@zg.tel.hr>]

Ever since I red  ATM books 1,2 and 3, I noticed a habit
of ATM-ers of Russel Porter times to mention ( proudly) if they
obtained some part for their telescope for $0.3, or so. With years
and inflation this sum has raised to somewhere in the $ 18,5 range or
so, but not much more.
This is so even today, our List is witnessing the phenomena.

But if our fellow ATM-ers will acquire something in the orders of
magnitude higher price class, as a rule, there will be no mentioning
of the price as if this is obviously not interesting for anybody or even
indecent. Milling , turning, and other machines are discussed  as they
are for free or obvious.
People are working with 20 " blanks not mentioning the damage to the
wallet they suffered, but they found it necessary to announce they bought a
scrap pipe
 for  1$.
Everybody is salivating on the recent " scrap yard " buy of 16", 3.5" thick,
probably Pyrex mirror. Nobody dared to ask for the price nor the proud
owner find it worth mentioning in a good old ATM tradition .
Interesting habit. Is not that so?
But why?

So David, please satisfy my curiosity ( may be off List).
What was the price for the beauty?
