[ATM] General questions before getting starting on a 6F6.

["Anthony Anconetani" <Anthony.Anconetani@genband.com>]

Hi everybody,
 
This is my first post to the ATM list. I would like to start by saying
thanks for all of the advice you all have already given me through your
various websites and posts. I hope to start work on a 6 inch F6 in the
next week or two.
 
I have some questions for Mike Lockwood (or really anybody who wants to
jump in...).
 
Mike, I stumbled onto your website from GotGrit. I really like your 10
F5.5 design. I hope to build something similar once I have a little more
experience. Anyway, from the first part of your Mirror Musings page,
here are some questions:
 
You comment that one should read at least two other pieces of
literature, I've read Berry's book and I'm planning on purchasing
Texereau's from Willmann Bell. Do these seem like a complete selection?
I've noticed some things seemed to have changed over the years. For
example steel hogging tools and tile tools versus glass tools. Is there
a more recent text that I should consider?
 
I'm surprised that one would need to grind the back of a mirror and tool
to 320. How much extra 80, 120,180, 220 and 320 should I plan on
ordering for a 6 inch mirror?
 
I'm planning on doing the initial hogging with some kind of steel item
(I don't know what yet...) and then switching to a tile tool. Should I
plan on fine grinding the back of the tile tool? How well does dental
stone on the back of the tool hold up to direct grinding? Does the tool
need to go to 320?
 
What are generation marks in a blank?
 
And lastly, I took your advice on United Lens. They we're a really nice
bunch of folks. I look forward to seeing the blank. And I hope I get a
chance to send them more business.
