ATM beginner tool questions

[Bill Mitchell <astronutski@yahoo.com>]

After lurking for three years and seeing all the fun situations you
all work yourself into my curiosity got the better of me and I have
ordered a 6" WB kit.  I want to make two mirrors out of the kit, an
f/4.5 first, then an f/8.  I have a few questions before I begin
though.

1) Is it practical to make a tile tool for a 6" blank?
2) Will the blank make good contact with the tiles during the chordal
stroke?  I'm thinking there will likely be dead zones where there are
no tiles close enough to the edge.  Will this be a problem?
3) Should I use something else to hog out and then pour the tool once
I get the general curve going?

Oh, and I am fully prepared to employ the famous "grind more worry
less" phrase throughout, thanks Ken 8^)

Clear skies,
Bill Mitchell
