Hey Steve, that's just amazing. If I only could see it in real life. That would be great.
How do you solder the 4 sides together without loosing any piece If the latice work while reheating? |

td9clyde: Well who ever wants to brave the snow can see it this week end
![]() Lorenzo, If you look closely at some of my previous posts you will see how the lattice is held together by notching the ends of the tubes. I can carefully pick the section up even without solder. Right now, I have to run down to the welding store this morning and get another bottle of Oxygen. |

Steve are you using silver solder on the boom? If it was me I'd use 50 % silver solder so it would take the strain and the flex. Ed

I tried the drag out some before we took the boom off and separated the top section for transport tomorrow. I noticed I'll need to add some counter weight. It may not walk very well because there may be too much weight on the nose of the tub preventing it from dragging along. I forgot to weigh the boom but I think it's around 25#

Many thanks to all who posted links to the GREAT videos of this dragline. This show will have to be on my list of things to go to next year. Your dragline is one of the most impressive builds that I can think of.

Steve-that's a great video of the 9W walking down the pile. I could see you were having some problems but I was amazed that the model would walk down a hill that steep. Did you walk it up the hill to start digging? Also I liked your hoist drum brake.

We walked up the planks, Scott,Ed and my son Mike all helped. Scott and Mike had to squeeze the shoes to the planks like when I stepped on the shoe in the video for traction. I had a low voltage problem too going up and couldn't get the cams to lift the machine,probably because we ran a little cord over 50' because we didn't have our own drop from the ceiling yet. Two of my buddies, one who worked on real draglines for years sat by and watched. They said; "when ever your ready Steve let us know
![]() ![]() I'm going to do the math and see how I can remedy the hoist problem. I think I'm running right on the borderline with the current draw. When the point sheave is made it will be 3-5/8''dia. vs the 1-1/5'' one now that should help some. The dirt we had was really heavy too. I definitely need to make the cleats on the shoes and it should walk nicely on dirt then. |

Well I removed the hoist motor this evening and found my culprit. On the shaft that runs from the hoist motor across to the pinion that drives the big gear on the hoist drum there was a key missing ![]() |

Good to hear it was a easy fix. Thanks for pics and videos from last weekend. If (when) my D8 is ready I may build a dragline, have always thought that boom had to be in steel but you have showed that brass is ok.

Glad to hear it was not a major problem steve. Guess it could have been worse. To bad it had to happen at the show but I guess there is no good time for a break-down.
