With all the welding done the bumper comes in at 42 pounds, 10 less than the OEM Toyota bumper. instead of welding caps on the ends of the bumper I chose to use removable ½" x 2¾ " nylon plastic plugs, I cut them close to size then used a plane to make them fit snug, I'll drill a few 15/64 holes in the bumper, set the plugs in place then drill them to 3/16 for the screws.
From my junk pile a beefy lifting arm from an old hydraulic floor jack, should work good as a pivot.
The lifting arm is wedged between those two plates, I'm using the 2¼" O.D Telespar for the main boom with short sections of 2" Telespar slipped inside wherever it's bolted along with ½" I.D steel pipe spacers to prevent the Telespar from crushing when tightened, the plates are 1/8" thick 5" x 8"
After weeks of working on the new bumper/crane build it's pretty much done, working on the pins to have two positions for boom height.
Drilling the ends of the pins to accept these pull handles using thin rod makes installing/removing the pins easier.
Boom in the low and high position.
The whole crane is a take down design for easier storage and makes for lighter pieces, the heaviest piece is the swivel at a reasonable 28 lbs, the whole crane including the winch weighs 80 lbs.
