Well if it machines not too bad then I will use that for next project. I did look into McMaster and the different tool steels, easy to machine.

Like I said before I can't take the boom apart cuz of seized screws (without a lot more work). I was using the 6mm shaft for centering the part on the table. That way I could make sure both top n bottom were lined up.


And bushings, bushings, bushings. Also used them for a bit of spacer.




And made this up, some added support for end of stick where bucket connects. I do want to add weight to the machine but not to the arm, rather like joes idea of plate steel on frame. Somehow I'll bulk her up .

The drill rod could be in it's tempered form ( not heat treated ) .

I'm not sure what grade the drill rod I have been using is. The local metal supplier only has one kind so I just get what they have(blue paint on one end). I know that I overheated the piece I was referring to. I welded a very small piece to a big piece and then tapped it with a hammer to straighten it. It broke right off but not at the weld. Anyway, I went back to using mild steel for those parts because it's much cheaper and I save the drill rod for the important parts!lol

Sorry for taking your thread off topic RW. You're doing a great job on the excavator rebuild. By the time you are done it will be a whole new machine!
