I have been able to use converted door closers on all of my props so far but they only have about a 7" stroke. I need to find one with a 11"-12" stroke for my new build. Does anyone have a source for cheap pneumatic cylinders? I don't need stainless or anything fancy. It's a light-duty application. Under $30 would be ideal.
Thanks for the warnings. I'm going to at least try the bimba since the price is what I was looking for. The prop that I'm building is horizontal on a ball-bearing drawer slide so lifting power is not a problem.
