ATM foucault tester built

["c f" <quantemlp@hotmail.com>]

Hello to all,

I sat down last saturday and built a foucault tester from the stellafane 
site ( 
http://www.stellafane.com/atm/atm_foucault_tester/atm_tester_plans_1.htm#AltMeasure 
)  It took me about 2 hours to just about complete it, with the exception of 
the electronics.  I purchased 2 diodes, both red as a light source.  one a 
850mcd 1.7v and the other is a 5000mcd 2.4v.  I ended up using the 5000mcd, 
with the top cut off with a drummel.  this seems to work good at this point 
although I have not tested it with a mirror. gona make the lap this weekend 
and start polishing.  Anyways,  I needed a razor for the knife edge slide I 
made, saw the perfect one over the kitchen sink sitting in a my stove 
scraper.  removed it, cleaned it and placed into a slide.  It wasn't doing 
much.  (hmmm wonder what my wife will say when she goes to use it? ) once 
the pitch is poured and the polishing begins I will test it.  I am still 
tossing back and forth on weather to purchase a lap mold, or use a piece of 
wood I have, cut the slits in it and fill them with silicon, leaving some at 
the top, then overlay that with a piece of tightly pulled plastic bag or 4 
ml plastic sheet, once dry pull it from its mold. this will give me the same 
affect as the purchased mold. I can then put this on the mirror, and pour my 
lap onto it and it should work just the same as a lap mold sold.  but I am 
still tossing around the idea.
