Pretty slick, Thanks for the reply on the HM-52 Chich thread. Quick question, how are these cylinders rated? Say for example, your head and motor weigh some 250lbs where as Chich's knee and table some 500? so what is the methodology used for the correct sizing and pressure required. I realize there is usually a little "you figure it out when you get to play with it".

So, if there is a little insite you could share concerning the sizing for specified load, I'm all ears.

Thanks

Ron
