Thank you Scott, this is helpful. I also thought of making the bushing for the tower from water 3/4 and 1/4 water pipe, but was hoping to find DOM tubing at a reasonable price, with negative results so far. Interesting to me is that one of the members said why not use bronze bushing inside the steel pipe bushing. The 3/4" sch 40 steel pipe is supposed to have 1.05" OD and 0.82" ID. I found a local source of bronze bushing with 0.75" ID and 0.875" OD. That means I could turn the bronze bushing on the lathe from 0.875 to 0.819 and the bushing would have 0.034 wall thickness. Seems to me a little thin though.

I like the idea of the bronze bushing Eugen. I didn't do that with the 646 when I rebuilt it. A member from the original site mentioned it after I had already had the pieces made. Like I mentioned before I increased the size of the rod to one inch. I had a piece of double extra heavy pipe in my scrap pile that I bored out slightly to make the support areas in the tower and the arms. It was also mentioned by someone that most small loaders don't get a lot of work to justify the bronze bushing. I just like the idea of the bronze in a wear area.

If I were in your situation, I would use what I have.
Put a couple 1/2" plates together, shaped to fit the loader uprights. Weld short 3/4" pin at inside end only. Drill and thread four mounting holes. Drill through uprights to fit mounting holes.

I like this solution @FUTZ ! I think I could make this be maintainable too. Thanks for the idea!

The old trusty Milwaukee portable bandsaw. Slow but steady got the 1/4 plate cut for the tower inserts.

Makes a clean cut. I lot nicer than me with a torch!

Neat tool. I wonder if a cutting oil would have helped some.

Well, to be fair I did try the plasma cutter but as Jeff says, not nearly as clean a cut. The limitation of the bandsaw is clearly the length of the cut, and low speed, but it was fine for these small pieces. It helps that it cost me next to nothing, got it used.

Good point about some cutting oil @Propane57, didn't even come to mind. Problem is, that third hand needed for it. Or maybe just put some motor oil on the line and cut on it?

On to the next adventure. Drill holes for the pipe to go through, and weld the pieces in the tower. Ahm.. wait, first I need to hook up 220V wires to the outside of the house because I want to stick weld it.
