RE: [ATM] Making glass blanks

["Thomas" <tomjan@ozemail.com.au>]

Yes there are risks, but then again crossing the street is taking a
risk. Where should we draw the line on risk? 

I agree that with the current cost of blanks this is a somewhat futile
avenue of investigation, but then again maybe not. We all have our pet
interests.

Mine right now is building a vacuum plating set up, and it looks like
I'll be building the diffusion pump myself, so I'm not going to start
saying this a dumb thing to be considering (making blanks), but rather
we should be asking why does he want to make his own blanks? Besides you
don't have to start with glass dust, you can start with cullet, might
take longer to get the bubbles out, but it's safer for your lungs.....

These `lets grab a bucket of sand and mold our own blanks' threads
always 
amuse and scare me a little .

When you can buy a precision machined blank, edged , bevelled , back 
blanchard machined, front diamond generated , fine- annealed blank , for

such a reasonable price from a number of vendors why would you risk your

life trying to prepare the quality of the above in semi-ignorance with
sub 
standard equipment with such a life threatening material. It is the 
finishing that produces a nice blank: the annealing is cheap and the
least 
of the expense.  One solid exposure of not fully  filtered glass dust
can 
set you up for a life that is cut short by 15 yrs  with emphesema'.

You might as well join up and and head for Iraq.

Why the hell would you risk it?
