I think he backed off one side of the boat ramp and hooked it on a rock pulling it out, but we didn't talk a lot about it. He was embarrassed.
No caboose and no casting? Just what do you do?
Thanks, Bud! I did put my name and 2018 on them. I like leaving little surprises like that for someone who will never know me.
Thanks! Some holes you need just have no good alignment references, like these which should be angled to a non-cylindrical housing.
Of course a hole through a shaft can be lined up on the OD of the shaft if it's not offset. I have turned a boss on a plate then bolted that down to the mill table to align something with a damaged hole so I can machine it part way through for a sleeve.
I was in too big of a hurry. It looked like it was bent outboard of the inboard bearing location which is next to the step for the seal. But it was also bent in the bearing location. I didn't measure, just eyeballed it. Mistake number one. Then I found a piece of pipe to fit over the shaft and bend it, but it was not a close fit. A close fit would have kept the shaft straighter. Mistake number two. Thinking the bend was away from the step I did not heat the shaft enough. I thought about putting it in the forge to get it all warmed up but was too lazy. Mistake number three. However, it will run a long time like it is, we intentionally left the bearings a little loose to accommodate the misalignment and not overload individual rollers.
Great job in the bush! Your options being limited may help. Had I had to bend this cold I would have used the nut to bear upon and it may have bent more reliably where it was needed.
The wheel was bent. If you are insinuating I would use a bent piece of scrap wheel to attempt to make high quality castings I am appalled. What do you think I am? A man with no standards?
He brings me aluminum so I have to assume it was steel or it would be here.
Thanks on the motor mount comment.
I note the sarcasm on the baling wire comment, however.

No, in answer to your followup question, I do not weld with coat hangers. They really are not good metal, but baling wire is. You just have to straighten it and sand the rust off and it does make a great welding filler.
Note to others: Guys welding with baling wire and coat hangers is a big joke among professional welders.
Wish I'd done better, but it's running down the road. I had to think WW1/2CD?
I suggested that but it would have taken a couple of hours including cutting the old stub out and welding the new one in. He was in a hurry, having left his wife at the lake watching the boat.
But new ones are about $25 so it's probably better to buy a new one.
Threaded 1-2-3 blocks are handy. Some cheap ones aren't threaded but they have uses too.
How do you put a hole for the tool in a handle you've made? This works pretty good. When I'm making a handle from a stick of firewood I don't take the time to square it up, just chuck it and turn it, then all I have is the spur point to line up the handle with.
Thanks for all the comments, guys!!
