IM UPDATING my last question about disconecting.

IM UPDATING my last question about disconecting the power seat to work independently from an external source. I want to use this chair as the ultimate desk chair. I have a super heavy duty support frame made out of 24 gauge steel and an equally heavy duty gas cylinder sitting on a 5 leg exec base that will support 850 lbs. I want to use the chair as is with all the electrics. I know it sounds crazy but its the only solution to years of shitty office chairs. THIS WILL ROCK if I can get it going. I am handy with electrics etc, so perhaps someone has an idea. Ive looked all over the web and noone seems to be attempting what I am doing. The chair is built like a battleship and that is exactly how long I would like it to last too. Hopefully someone's ear will be tweaked and could point me in the right direction. This is certainly a unique design that could catch on if I could take care of the switching problem. Thanks for the help.
