Well, I'm at the boat this weekend, getting her ready for sale. So I can't stop poking around the American Hoist & Derick steam donkey that is displayed at the marina. I'm taking lots of pictures and making lots of notes. The thing is mostly complete but rusted solid. I can't help thinking what a great project it would be, but I don't know if I have enough years left in me to get to it. I think I have seen a model on line somewhere but can't find it.
If anyone is interested, I'll post some of the detail photos and some drawings from time to time. If anyone knows of a set of plans for this let me know.
Here is the first drawing. This is the big end of the con rod and is exactly the same as the cross head end. What do you call this type of connection?
By the way, as rusted as it is, I found about half of the two dozen grease cups could be unscrewed by hand and still had grease in them.
