I'm not sure what type of design you were going for but here's what I did to mine....

First, I used an extension damper to give it some hydraulic resistence, as I raised it. (I originally thought that was going to be enough to hold it.......not!)
It held it somewhat but the handle was still a little too heavy and it would slowly start to fall. So, I added a couple of springs, on the tail end to hold it.
They're not strong enough to lift the arm but strong enough to supplement the damper's holding ability.



Hope that helps! \:\)
And nice work BTW!!!


Can you tell me the manufacture and part number, of the hydralic damper you used on your collective???? a link to a site or store would be great too
