Re: 1/16 Bucyrus-Monighan Walking Dragline
Steve-I think going to Dragline World with some equipment is an excellent idea!! I talk with him 2-3 times a week and he seems to be lonely and is disappointed that no one is coming to D.W. any more. This would be good for him and let him see how R/C models have progressed.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Steve-not this time. I have been trying for 2-years to plan a trip up to see him but something always gets in the way. I still plan to make it though.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Been idle since Labor Day. I decided to get my machine out of the trailer and do some wiring on the control console. Scratched around through my junk pile and came up with these components to wire some of the buttons on the 1:1 Marion controls. Hope to have some of this done for Cabin Fever in two weeks.

Re: 1/16 Bucyrus-Monighan Walking Dragline
RC draglines are rare and this is the biggest one I have seen. this machine looks like it can manoeuvre a lot of dirt. are you using a clutch system for the winches?
looks amazing, you did a really amazing job. |

There are no clutches, all 3 motors are: 100vdc PM motors individually driven by 4 quadrant regenerative drives. The only clutch is the jaw clutch that engages from drag to propel motion. Eventually I will build the brake bands so I can set the brakes when needed. Thanks for the compliments. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Your welcome. I am a big fan of draglines. This is probably the best RC dragline I have ever seen.

Ya, it's cool! Just the clanking noise the spreader bar makes hitting the bucket when you slack up too much is neat!

Re: 1/16 Bucyrus-Monighan Walking Dragline
Look at the Cabin Fever Discussion Thread on the "Up coming Events thread"
As far as I know everything is a go. Wish you could make a trip up this way. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
steve-I look at the discussion thread every few days to see what is going on. I meant was there anything new with the dragline. After reading that your machine had spent a long time in the trailer I am guessing you are very busy. And yes, I had always hoped to make a trip to that show but now I doubt it will happen.

I got the incoming power supply wired up pretty well this week. Now I can shut off the power from the operators seat. I don't have the time to wire the radio up better. I want to use the auxiliary switches on the radio and wire them to the switches on the console to set the parking breaks on the 3 functions . I want to try to take all of the guts out of the DX7 and mount them to a board so it is easier to work on the wiring. I plan on having a flip down access panel on the bottom of the right hand console. That way I can make adjustments to the radio easier. Right now as you can see the radio just hangs inside the console with wires hanging out. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Now I understand what you are doing steve-seems like you have a good plan as usual. This will be a really nice set-up when finished. Have you had many ex-operators come around and want to give it a try?

Found an interesting panoramic view of a cab of a 9W while looking for something else.

Re: 1/16 Bucyrus-Monighan Walking Dragline
I just read through the whole thread, and this is nothing short of amazing.
If i can make something even 1/100th as awesome as this i'd be more than happy with it. What made you decide the 9W was 'your' machine to do this epic of a build? |

Thanks for the compliment. It all started in this picture here; the spring of 1994 the day this machine was cut up for scrap. That's my 1998 Ford Ranger sitting next to the 9W. I took about 8 pictures of this machine but ran out of film and didn't take more. Originally I was going to build a Manitowoc 4600 crawler dragline but didn't want to take the time to machine all the track links. About the year 2000 I think, the coal company sold all of their remaining machines at auction and I went and tried to buy the 1:1 bucket from the 9W but was outbid by someone with deeper pockets. My plan was to take the 9CY bucket to our steam show and set it there as a display. Actually the bucket was supposed to be taken to Station Square here in Pittsburgh to be displayed with some of the old steel mill era relics. This machine was bought new in 1939 by one of the big coal and steel tycoons here in Pittsburgh. After the auction, A friend of mine who is good friends with the auctioneer, gave my buddy a pickup truck load of old parts books and manuals that wasn't sold. I went through them to see what I wanted and found the parts books from the 9W. From here I was able to figure out a scale that would be appropriate to be able to actually dig with. Being a machinist building this thing isn't all that hard for me but trying to get actual drawings and measurements is hard. I originally was going to wire this directly but it would make it too complicated with all the wiring involved so Radio Control came up. Not knowing anything about RC I went to a local hobby shop to ask some questions, only to find out no real knowledge on what I am attempting to build. The man there told me about a forum called "GardenTrucking" This is where I started to learn more about this hobby and met a lot of nice guys in the process. Since then countless hours have been spent on my hobby when time permits. |
