DESPERATELY SEEKING MOORING: San Diego
Here is what I did.
Went to a local excavator, you know, earth mover, bulldozers & such. In his scrap I found two John Deere 450 bull dozer drive sprockets, maybe almost three feet in diameter. I think I gave him $20. Then went to a junk yard, lots of junk cars & trucks. Found a truck rear axel with about a six inch flange on the outer end and about a three 1/2 foot shaft, maybe 2 3/4 to 3 inch shaft, $15 for this one.
Laid one sprocket inside the other, they are slightly dished, brought the axel shaft up through the sprockets, bolted and welded the whole thing together, bent a 3/4 inch steel bar into a U shape to fit the outer end of the axel, welded it on ----- and walla ------ I had a mushroom mooring anchor.
I took it to a weight scale here in town and I think it weighed 361 pounds. I will not promise all dimensions here are exact, it was six years ago. I fastened a 3x3 foot piece of 1/2 inch plywood to two 2x4s for handles & support. Laid the plywood with the handles on the underside, on a 14 foot aluminum boat, had a guy with a wrecker set the thing on the plywood, rowed out to where I wanted it, put the mooring buoy and chain in the water, after attaching it to the anchor bail, stood up in the boat and lifted the handles up & in she went.
The mushroom will hold a lot more and a lot better than a engine block.
