Re: 1/16 Bucyrus-Monighan Walking Dragline
Awesome piece of kit, a well crafted Model of a dragline
Been reading this topic for ages and finally decided to post a comment about twenty years ago I was working in demolition (when I was younger and fitter (now 48) and was watching the dragline operator that was knocking down a pre-fab concrete building with a 1/2 ton ball, he was getting the building down in no time at all and was a artisan at driving the machine, I believe it was a Ruston-Bucyrus machine and ran on tracks, it was of 1950's vintage, I sat in the machine one lunch time and went what the **** do all these levers and pedals do, I had not got a clue.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Looks like a great day steve! That's a big pile of dirt there. Maybe a yard?? The 9W must have been working perfect. That looks like sand. If so did you have any problems with the sand binding the moving parts on the bucket?

There were no problems with anything binding up on the bucket. It digs nice but I still want to make the bucket as close to the 1:1 as humanly possible. We still need to learn a good digging pattern so we aren't sliding sideways as seen in the video a time or two. I hope one of you guys bring a dozer some day to clean the roll in front of the fairlead such as a certain Terex or D8 |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Thanks steve-the reason I ask these questions are based on the troubles I have had with my dragline. Sometimes the fine dirt gets in the trunions and the bucket will not dump. I have to take it apart and clean it. It's not a big job but I know the real draglines don't have this problem. I must have done something wrong but not sure what.

Re: 1/16 Bucyrus-Monighan Walking Dragline
I haven't done anything on the 9W for a while but one thing I need to do before taking it out in two weeks is, I need to machine 6 cleats that go on the bottom of the shoes. I scanned a drawing and they can be seen in black on the drawings. These little Vee's will enable the machine to walk better with some traction. What happens now is, it will either just slip or pivot around the other one getting a little more traction. This is very frustrating when on any kind of incline especially. Just ask Scot and Ed.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Here is my progress on the walking shoe cleats. I think now we'll be able to walk up a 10% grade. Definitely on level ground too. I should add about 15-20lbs ballast in the rear of the revolving frame to compensate for the boom now installed because the edge of the tub is somewhat heavy and not sliding along easily while walking.
Roughed in pieces: Cutting a 45deg. bevel: Beveling the ends: Attached with #1-72 screws: Ready to walk again: |

Good job Steve. That will make loading a lot easier too.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Looks like it should do the trick for you. I want the full size equipment besides the adjustable table What I wouldn't give to have room for full sized machinery

Re: 1/16 Bucyrus-Monighan Walking Dragline
Getting ready for this weekend for another "BIG DIG" I finally took the time to build a suitable shipping box for my machine. It measures 174''x40''w x 48''h. Now I'll be able to haul it on my gooseneck trailer with some other stuff.
I want to put some eyebolts on the sides to hook a bungee cord to give the boom a cradle for a cushion ride. Another quick fix was to break some welds on the bucket so I could bend the teeth down a few degrees to give it a better bite. This is still going to be a temporary bucket till I can fabricate a better replica. A quick set up in my press brake did the trick: |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Nice box, guess it can be used shipping the machine abroad
Temporary bucket, hmm, guess I would be more than happy with a final bucket like that one! Couldn´t make it to Brownsville next weekend hope to do it next year, this is a very fine show, I would say the best one. Dan |

I talked to Smallhaul earlier this evening and he was already at Brownsville. I was still loading my trailer so I can leave home tomorrow early. From his report the Thew steam shovel has to be moved out of the shed so we can get our pile of dirt under roof in case it rains this weekend. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Nice work steve-you should think about becoming a machinist !! That should give you good traction now. The show sounds like fun! I hope you have someone to take lots of pictures and videos!

Re: 1/16 Bucyrus-Monighan Walking Dragline
Adding some pictures of my machine to this thread I have elsewhere on the forum.
Aerial view from the D9G I clamped my camera on where the operator's cab will be to get an operators perspective. I need to cut the excess links off the drag chains now that I have tried digging with them shorter than I originally had. I think now they are closer to the proper length per scale. I can also dig about 3'' closer to the fairlead now. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Like the operators perspective.
Thanks for posting them Steve. |
