4005, Welcome to our desease. That is a link to another thread here in the forums where you will find some ideas of how to make a CG machine @ home. If it is not clear enough pm the guy & I'm sure he'll be more than happy to give you more details.
In RcKen's PIF build thread of the LT 40 you will also find a simple method of lateral balancing by using a string cradle.
I'll let Ken expand on that for you because after all he is our resident building guru, even FRIDAY! [sm=eek.gif][sm=lol.gif]
