Go to Post Last year we saved a ton of money by using a good bit of square tubing for the frame of our robot, square tubing is a lot cheaper then C channel. We get to use so much raw material that the cost should go down in certain places. - Derrick Maust [more]

Re: Gas charged hood lifts: are they legal in 2016

I don't know for sure, but given the general behavior of gas springs, it doesn't seem likely you'll be able to run them much faster than a few cycles per minute without using greater forces than they're designed to handle. All of the ones I'm familiar with have internal flow control valves that limit the rate of motion, especially in the extension direction.

If you want to be able to extend/contract quickly, you should consider switching to regular (steel helical) springs, probably compressional. Perhaps a storm door spring could work (wrong direction).
