To all the folks who asked about the u-bender, I'll post something after I
get back from my spring break (next wednesday).  I'm just trying to get out
of town right now.  Sorry for the delay.

A poor mans u-bender consists of a set of pipe benders from JC Whitney, 
clean fine sand, plugs for the pipes and t-clamps.  On one end of pipe 
to be bent insert a plug and t-clamp it in. Fill other end of the pipe 
with sand until almost full.  Insert the second plug into the open end 
and clamp the plug in. Bend the pipe using the pipe benders. 

The sand is the secret to keeping the even radius bend, it does not 
allow the pipe to compress.

Works with all different size tubing.

I use the AD594 device to compensate and linearize thermocouples.  

Does anyone have experience multiplexing in front of one?
