Hatch lifting systems are fairly common. Bennett makes one. Reinventing the wheel would be a monumental waste of time. I wouldn't bother trying to jury rig something with a device that wasn't intended for that purpose.
Paying several thousand for the convenience of not having to yank my arm off is exactly what I was trying to avoid.
I used to work for a place that bought cylinders, we bought them in bulk, but paid about $100 per cylinder, (remember these are a steel tube, a steel rod + some O-rings).
It only cost $250 to replace a hydraulic pump for an outboard lifter. The CHEAPEST hatch lifter I've found so far is $2,200.00.
I would rather jury rig something. A hatch isn't a rocket.
Nothing for nothing Capn_Bill, but Nowhere in your original post did you mention that cost was a significant factor in your project. Simply look at the original post and you'll see that your criteria was not clear. You posted about designing a solution and it was simply pointed out that the solution is already available.
