[Robotgroup] Casting plastics

[Nick Pietraniec]

Does anyone have any experience casting resin?  I'd like to do  
something similar to the taillight casting in these howto's

Just wondering if there's someone out there wants to offer some words  
of encouragement or warning about what not to do.  My impression is  
that in order to end up with a reasonably bubble-free cast I'll need  
to use a vacuum chamber to remove bubbles.  It looks like the cost of  
entry into the world of casting is relatively low, so when I fail I  
should only be out a few bucks.
