[TheForge] Special Screw

[theforge@mailman.qth.net]

Thanks for all the input on the screw I'm looking for.  I called Starrett this morning 
and they make calipers that use the screw & nut I'm looking for.  They use them on 
their catalog #26 - Firm joint caliper.  The nut is a .225-40 and sells for $2.80 and 
the screw is a .225-40 Hex x .308long and sells for $3.75.  Since the alternative is 
making them, the price is dirt cheap.  Still would like to find another source though.  
Starrett makes this caliper in 5 sizes from 6" to 36".  

The exploded view of Starrett's caliper shows it like Bob S. said, one leg has a 
square hole in it and the other a round hole.

My "girlie" calipers so far are:

One that I copied out of a French (naturally) ironwork book and just uses the 
woman's legs.

One is from an IVBA newsletter that was in there courtesy of Brian Gilbert--he had 
found it on the internet.

The last one is the chrome plated lady that you see on the mud flaps of semi trucks.  
I just straightened her out (don't I wish) and made her into a caliper.

I haven't made any of these calipers yet but will as soon as I get the joining method 
determined.  If any one has a caliper of the type we're talking about here, I would 
sincerely appreciate a tracing of the shape of it.
