deepsnow,
I hava attached a picture of my hook (sorry, it's not the clearest) although I do have a welder here, I haven't as off yet lesrned to use it, So wanting and needing a hook, I chose to bolt mine on. Atleast for now.
I used a grab hook that has the open throat and a pin so you can attach it to a chain link. I removed the pin, bought a hardened bolt long enough to go through the hook and the bucket and to allow some Extra Big washers inside the bucket.
I also bought enough washers to fill up the gap (opening) in the throat of the hook (where the chain link would normally go) and dropped the bolt through the whole works. Drilled the appropriate hole in the bucket, added the Extra Big washers and a lockwasher on the inside of the bucket and then double nutted it.
I have lifted probably 300 to 400 lbs. with it soa far and it seems to work fine. I do keep an extra good eye on it for signs of stress to the hook, bolt and bucket, for safety sakes.
