Thanks all.
Joe, I can't remember what sizes the cables are. I've been experimenting with 3/64'' , 1/16'', & 3/32'' 7x19 to see how flexible they are. But to be scale the drag (2'')=1/8'', hoist (1.5'')=3/32, boom ropes and bucket dump (1'')=1/16'' |

Got some more progress this week. There's a lot of tiny details unforeseen here. Still need some splice plates.

I've been working hard on the slice part of the first section still. Came across a small problem where the side, top and bottom diagonals attach in the seam area but figured out a fix because soldering a bracket on isn't strong enough. If I was working in steel I could just tig weld it on. I probably could tig the brass but don't want to chance ruining a tee chord and a few hours machining a new one. I don't have any pictures yet.

Steve-I think a silver solder joint is about as good as a weld when done correctly but I'm sure you have this situation covered. Let us see pics whenever you can.

Here you go Tom. This is what I was talking about. I made these angle pieces that bolt on rather than just be butt welded on. The wall thickness is .020'' at the thin area. On the top view I don't have the 1/4'' tube milled yet,that's just one of the lattice pieces,also at that point there's two 5/32 angles back to back only one shown. Maybe by next week I'll have most of this area built I hope sooner.

Excellent nice machine work but very expensive with all that brass. Ed

Got some progress from all the thinking going on. It sure is nice to see how the pieces are coming together after several hours of machining and procrastinating.
I did a count of tubes that need milled for the top and bottom surface still and there's 44. ![]() ![]() ![]() ![]() ![]() |

Looks really good steve!! Have you counted how many bolts will be in just the boom?

HMM. Probably around 700? I do know there will be 76 at each splice.

Wow. 9W Monighan, I remember your post from Scale 4x4, and replied a few times there, but now that I've actually caught up with your build over here, all I can say is this project is truly a labor of love. I loved looking at all the photos of the machining, in process. This is truly an epic build. I am in awe of your skills and talents.

Thanks,Nathen.
I spent most of the weekend working on the boom but only made 8 pcs. and half of 8 more tubes. Too many distractions updating the drawings. There's still about 36 more to go on this section. Sorry no pictures today. I probably could have gotten more done if I didn't have to sit on my porch giving out Halloween candy ![]() I'm almost to a point where I can solder some of it together. |

Haven't done anything this week but drive to Baltimore,MD. and then up to Youngstown,Ohio to deliver a job and pick up a load of steel bar for my real job. While on the way home from MD. I wanted to stop at Dragline World to see Jim but I didn't have time. I hope to pickup where I left off Sunday on the boom but first I want to work on another paying job I've been fiddling around with this week.
