I had a question from another site on how I'm joining my parts.............

All of the above. I tig welded the ends of the steel beams where needed. Bolted with literally thousands of 0-80 bolts and up to 1/4-20 bolts on parts not seen. Riveted pieces together on the brass exterior with .040'' dia rivets. And I'll be soldering and bolting the brass boom sections.



Early stages of the ESCO bucket.


Bolting nightmare!

I finally got to solder one of the side pieces together. It was a little tricky till I got on to it.
Here's the last mock up before soldering....

Hot out of the fixture. I still need to do some soldering on this side where the solder didn't flow thru.
