I am not an arborist but am trying to set a pulley/ ring friction saver to hoist a deer feeder 30' in a tree. I have the friction saver installed but am not sure if it matters if the ring should be on the load side of the pulley or the working side. I am only trying to hoist 100lbs but there seems to be a lot of friction that I am having to over come. I am using a boat trailer winch and my angle of pull is less than 45 degrees. Any help would be appreciated.

Because you are only redirecting the pull with the friction saver, you are still pulling the 100 lbs, plus some extra to account for any friction. I can't visualize the ring/pulley configuration. However, if you are having the rope bend over that rings, then you will have friction.
Would also depend on the type of rope, a three strand would have more friction and say a 12 or 16 strand.
What I would do is set up a fiddle block, that is, put a pulley on the feeder. So your tie off will be up in the tree, rope goes down through the pulley on the feeder, then back up to a pulley at the tie off, then down to your winch. Gives you more mechanical advantage, but requires more rope.
How do you get the deer to jump that high in the tree?

As I understand it, he has an ART rope guide type of system and is using cable to pull the feeder up. It shouldn't matter which way the cable feeds thru the pulley. I assume the feeder is a broadcast type or he has mighty big squirrels.
More pulleys could make for an easier lift.

Depending on the size of the tree and work to be performed, it is a good practice to set a rated climb line on a friction lowering device to a base anchor pulling up a pulley with your DRT system up set on the line to the friction/device to the base anchor to the top of the tree. now you can work with less friction (pulley smother than traditional friction saver) and give the groundsman the ability to lower you (god fore Bid) in case of a emergency.
