Don't remind me, I did enough of that for farm machinery, in brass and steel, to keep crap rotating for harvest.

Bill, that could be considered an insult

So, today the plans of mice and men had a meltdown. I was coerced into helping mount a gate that I built 4+ years ago, and could not even remember. And the temp was below freezing and we were in the shade.
I was rewarded with a hearty chicken soup made by an old Croatian mammy so it was ok.
Today I got the wire wheel out and brushed the smoke and flux off the project and took a look at it. Seems ok.
Chris tells me he has never seen one successful on the first try...but I think this will do it, if some obvious stupidity does not raise it's head.
So I cut out a dummy from scrap without any pin hole, to see how the ears for the brace will look.
I did try a file on the T1 steel and it bites in, so I can drill it if needed, but it is definitely tough stuff.

My comment was for a hydraulic operated thumb. However, most fixed thumbs I have seen built did not come out right on the first try either. At least I have never called you an ENGINEER!!!

True, that.
I am making this to be able some day if I or a future owner wants to substitute a cylinder for the brace rod, to have that option available.

Today I managed to get another shop day in. I spent a lot of time making little holes into bigger holes on the lathe. I had given up on the 1.125 annular coming in this week and wanted to get'er done. Once I had machined 5 collars my wife walked into the shop with the mail and there was the rotabroach.
I also machined down a piece of cylinder ram for some 1.125 shafting for the pins on the brace.
I was pleased to see less than 1 thou taper over 14 inches on the shaft.

Now a question for the brain trust.
I dropped the bucket as planned, because it was a bit floppy when I bought it, and punched out the bushings. Or tried to....somebody in their wisdom had put some undersized bushings in there that were loose in the stick bore, and spot welded them in. So a carbide burr fixed the broken welds. The stick bore is 40mm and the bucket pin is supposed to be 30mm, but was 1.5".
I am considering making a nylon bushing 4.75" long and pushing it in there instead of two 1" long steel bushing.

What do you think?

The nylon might hold up fairly well for you. Or are you planning on starting an excavation company and it will be digging 8-10 hours a day?

At least the nylon will not rust out.

I am working at being retired and don't think I am good enough operator to sell my services on that machine. The only time it will be off the claim is when I do my daughters backyard re-contouring.

I would be happier if the wall thickness of the proposed nylon bushing was greater.

Can you use any grease on the nylon bushing?

Make a hard ass pin. use glass filled nylon for the bushing. The shit is pretty amazing under serious adverse conditions. As in high physical loadings and total contamination (trash, dirt, broken glass,hydraulic fluid) . The waste industry uses it for all sorts of slide shoes on pushout blades for packer bodies Etc. It can be abrasive to mating parts Duh!! glass is made of sand. For a lightly used home machine the bushings will last forever and a day. Look into it just my 2 cents.
