Yesterday the park manager gave me two books he's gotten during the last few
years. One is a nice paperback by Sam Brown a "all about Telescopes" which
has some sections showing some older mounts, don't show a dob, but dob like
mounts which it says can't be used to view the N.S.. The 2nd book is
"Amateur Telescope Making 2" by Albert G Ingalls and in a fast look in it,
it's going to be a hard read, it's got a lot of math in it, way above the
stuff I know. But I'll see what it's like as I read it. But this gives me
some 4 telescope making books. Oh ya, in the 1st one he shows a simple 2inch
folded reflector that can be made, that kind of make me thing a little.

Concentrate on building and learning to use the focault tester.
Without that you cant evaluate your mirror making. A tester
is simple to build, more difficult to learn to use because the
mirror and your eye have to be in exactly the right places. Once
you get the knack of it it becomes simple and you can set up and
test a wet mirror in seconds after cleaning.

I have one of those testers and it's can't be used in the trailer at all,
not enough room and outside I'id have to put up light blocking sades and see
if I could level an area that's long enought between my trailer and the
managers trialer, it's the space I go threw away. Living in a trailer park
is not the best of all places for such things.
This is a change that if I can clear out and get rid of most of the suff I
have in the one side area I might be able to use that area as it's has a
cement floor but I've got a lot of stuff to move out of there first.

It should even be possible to make a usable mirror while using very
little math - just rough out a four to six inch blank so that it will
form an "image" of the Sun on a (fireproof?) surface about six feet
away (moisten the mirror first.) After grinding and polishing, try
for a null figure using a Foucault tester.

Little typo there. I caught it just as I hit the send button.
Anyway if you just start messing around with a scientific
calculator it will teach you a whole bunch about math.
Also, if you want that spare setscrew just let me know.

Don't be bamboozled my the math. Get yourself an inexpensive
scientific calculator and start playing around with it. It can be
very
instructive and a good pastime on cloudy nights.

Those are good books, though certainly somewhat dated...
Sam Brown may be ageless... I'll never let MY copy go, though it's
dog-eared, several decades old, and has been loaned to many newbies over the
years... For folks on a seriously restricted budget, this book STILL offers
some excellent advice on how to build a decent scope, using easily obtained
simple materials... Never mind that it was written before most folks here
were born... I guess this is a good clue that I'm older than your average
rock...
And Ingalls is another classic... In fact, if you now have what I assume is
one of the ORIGINAL old series, it would be well worth your while to look
for the other two books in the series... So take your time and don't skip a
page... If the math pains you, just skip by it, because there's PLENTY else
in those books worth reading...
And the series has been republished, though the contents in the new edition
are somewhat scrambled compared to the original. Not that that necessarily
MATTERS... What MAINLY matters, is, for those who missed it the FIRST time
around, it's out there once more...
Of course, I can't let this opportunity pass without a shameless plug for
Leslie Peltier's Starlight Nights, if you REALLY want to round out your
collection (not to mention Burnham's, if you don't have THAT)...
And, while we're talking about old but well worth your time books, have you
read any Sidgwick, Muirden, Howard, Paul, Texereau, Suiter, Bell, or, even
Berry??? ALL good oldies but goodies... Well, Suiter isn't very old, but
should be in every astronomer's library, along with Rutten, and van
Venrooij...
Happy reading!!!

Back in the days of having to make your own mirror if you wanted
a telescope these two books and a couple others were standards.
Ingalls makes it sound a whole lot harder than it really is. I've
heard this was deliberate
to impress people with the accomplishment of making a mirror. Mechanics
Illustrated magazine ran a series of articles on making a six inch, f-8
telescope from glass blanks to finished scope which seemed too simple
after reading the above named books. Turned out
the MI scope was easy enough anyone could do it.
Mirror grinding is primarily cave man labor.
Final figuring to a good parabaloid is the tough part.
