Think about Somerset meet Jim.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That's OK about cutting into my seat time. I get a kick out of it watching the experts in action.

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
 

You gonna fly up Tom?

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

This machine in somewhat ideal conditions and swinging 90deg it can move a pile of dirt approximately 44" high in about 8-10hrs of steady digging. With damp sand that number would be higher.

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

its ok looking in the pics. you need to see it in person to relize
just what a monster it really is..

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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

Any updates before "Cabin Fever" steve?

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

The machine fared well in the trailer Tom. There is a bunch of surface rust from Labor Day because I forgot to spay her down with some WD40.

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.

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?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve,

You going to the lakeside dirt meet in Ohio? It is coming up pretty soon isn't it?

Jim

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I love this build, ever thing about it shows your dedication to building an accurate scale representation of one incredible machine. I still cant believe that a machine like this exists in the real world a gigantic walking crane!!!!!! sounds like something George Lucas would come up with for one of his movies.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Weather permitting I am going to go Jim. I'll know better next week.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Ha. The vintage1:1 machine this represents is small compared to newer models.

Thanks for the interest in my build. Wish I could work on it more but time is limited due to running my business.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

We got the 9W out of my trailer to get it ready for Cabin Fever Expo and I was surprised how bad it looked from the past few outings. Seems it rained every time I took it out or the humidity was so bad everything got rusty. I kept spraying the steel parts with WD40 over the years but obviously not on ALL areas.
I made the decision to dismantle the machine completely and do some much needed sandblasting and painting. I am also going to get the clutch working that shifts the drag mode to walking mode. Hopefully I can get the wiring done at the control console to make the shift.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Wow, ya that really picked up some rust huh?!

Couple more years and we will have to blow it up at Brownsville and scrap it!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

The rust never sleepes! Lucky you to find this out not a couple of days before show. I remember us having the discussion regarding paint or not. For shure, now the model will stand time and humidity better. My 463 scraper has been sitting in untemperated storage for some years now without any problem but it's painted of course.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

After several hours over the past three weeks I'm making some headway.
Here are the shifting forks needed to shift from drag mode to walking mode. I needed to do this for quite some time. I just needed an excuse to tear down the machine.

http://imageshack.com/a/img924/6463/XWThX0.jpg

Here they are fitted into the main machinery frame. I am still working on a method to fit a servo to make the shift. I also need to make a brake band to keep the drag drum from unwinding when the clutch is moved over to the walking clutch.

http://imageshack.com/a/img921/1752/ib3MdD.jpg

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Now that everything is torn down on the main frame and tub. I cleaned and primed them.

Wow, you better wear a name tag so we can find you now! Not gonna recognize the new dragline! :p jim

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

It sure is a shame that all that rust came on and you had to tear it all apart. IT is hard enough to put it together the first tome with out doing it the second time. Ed

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I knew it would have to be done someday Ed. I never put all of the screws in it because it would take too long to put them in and remove them when the time comes. It also costs a few bucks just to buy all the alloy socket head cap screws. I have a couple thousand on order right now at $.07 each.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Here are some more pictures of the I beam frame coming together. I spent about 28-30hrs putting this much together. Every hole had to be re-tapped to make sure the 0-80 screws go in easily. My thumbs and fingers get cramped up doing all those.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Looks nice!

Kerst

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Looking good! The rust is irritating but it's good motivation, ain't it?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That's looking awesome! Paint really helps, and having all the fasteners takes the detail way up.

I wonder if some removable lexan body work might help with future rust when running it at outdoor shows. Either leave it clear, or light fog paint so it's just translucent and doesn't hide the workings

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks Kerst. See you in a week.
Now that it is looking better, I am more motivated to keep going on the build. Just been very busy the past few years to dedicate time to work on this. It's also very fun to operate. If I had a full set of working drawings it would have bee finished years ago.
I am already going to have some of the outer skin be removable so people can see inside. Plastic is a good idea.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:D will you be doing any weathering and ageing to the inside and outside makeing it look old and used that would be so cool:jaw:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Jackvan, i thought he just took care of the weathering. It got blasted and painted. :)

Then you could really have fun with doing: Clear or translucent skins, solid colors brand new paint job, solid colors weathered like the day you saw it dismantled... make them interchangable.

That's such a cool machine, where ever you look there's always something else you hadn't noticed before.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

A Masive undertake to overhaul. I have to sit down when i look what's going on.
It's a True Masterpiece. Carry on Please. We help you unload carefully :cop:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I gave that some thought but I don't know how to do weathering other than how it looked prior to this rebuild. I know of a guy on the DHS Diecast site that weathers his crane models and they are superb.

Here is an example of a heavily weathered relic :D
