[Sneap] plexiglass control rods

[Larry Lamm]

Brian,
 Like Chris at TUNL we too have joined plexiglass rods that were too 
short by machining the ends and pinning the joint. This has worked well 
for us.
 Also, I have joined plexiglass rods using universal joint couplers. For 
example, the foil stripper control rod for our FN accelerator runs 
underneath the center of the column from the tank base to near the 
terminal, where it makes a significant jog away from the center line to 
reach the foil changer. I've used couplers on this rod, and this has 
worked well, except that some of the plastic couplers tend to get 
brittle in the tank gas over time.
