Billet Proof: What kind of hydraulics are used? I have light metal tops hinged at the back of our houses and have wanted to add a lift assist but don't know what to use. It takes somewhere in the neighbor hood of 80# top lift the tops. Then we place a notched 2x4 under them to hold them up for loading. Any ideas very welcome.
The lift up metal roof picture is at Roseburg Rod and Gun Club in Oregon. We used gas pistons on each side. I'm not sure the exact size, but they mount about half way back on the roof, and further back on the side of the house, so that they are compressed when the roof is closed. The strength of the piston will be determined by the weight needed to lift the roof. Mark
We have concrete roofs on our trap houses as well.
We cut access ports into the front edges (roughly 30" by 24") - these are centered over the entrance stairs and were then covered with a hinged aluminum cover. We did reinforce the roof supports with heavy channel prior to cutting.
There are many shoots that someone is in the trap house to keep things going. By constantly filling the machine there is no downtime between rounds to load the trap. They need more protection that a thin piece of sheet metal for the top. I say build them for human occupancy and safety. Properly built a trap house will outlast all of us here.
Our lids are metal, like what you would put on a machine shed, they have been shot and most of the shot glances off or flattens and sticks to the lid. The only place the shot goes thru is where the trim pieces are and that is because it sticks up higher then the roof steel, none of which makes it inside the trap house. You would have to be standing nearly on the house to be able to shoot thru the lid. If a direct shot is taken from the back the shot would have to penetrate a 24ga(?) piece of 1x1 metal tubing and a 2x6 plate on top of the concrete walls. I would stand in the trap house and let you shoot it with a load of 7 1/2s from the 16 yard line, and feel perfectly safe.
Any one figure out how to get in from the shooter side? Behind the arm and the hot zone of the trap itself? Our field is flat and we do not have the slope in some of the photos. Curious to see the pictures of roof mod so the stairs are easier to get to.
Thanks for the ideas.
RE: Maybe a trap you can walk into, with room at the side to store
If you have the money and willing to pour concrete anything is possible, but for easy way to load houses, as was this is all about, the pop up roofs are simple and sure makes it a pleasure to load a machine. Seen them all over the northeast, to include Canada, and in Florida.
