Re: 1/16 Bucyrus-Monighan Walking Dragline
I've said it before and will again WOW!!!!!!!!!!
The details are incredible. Did you build a line truck just for rigging it;) |
Re: 1/16 Bucyrus-Monighan Walking Dragline
amaized as always when I look at this thread. I have new respect for the length of the boom now.
Did you have the shop door open for these pic's? Carl |

Carl, The shop is big enough. I just need a 16' enclosed trailer now to haul it with the boom attached or build a water tight shipping crate for my gooseneck or skidsteer trailer. I remembered to measure the overall length with boom lowered and it came to 13'-5'' long. I'm going to try to fit in one of our work vans this weekend by resting the boom point on the dash board. I don't really want to use the big cube van with the V10 gas hog:eek: |
Re: 1/16 Bucyrus-Monighan Walking Dragline
:cool: Thanks Steve, I do understand about the gas hog:mad:. So, maybe a special trailer just for the DL and its support equipment would be worth looking at.

Re: 1/16 Bucyrus-Monighan Walking Dragline
That's looking great! I like the catenary in the hoist cables. It's little things like that that make it look even more authentic.

Re: 1/16 Bucyrus-Monighan Walking Dragline
It looks awesome with all the rigging. It makes it look massive even though it is a model.

Re: 1/16 Bucyrus-Monighan Walking Dragline
I finally got the boom hoist attached to the machinery deck and was able to boom up under power for the first time.
The motor I used had no problem raising it. We timed it today and it takes about 15minutes to get up to 25 degrees. Tiny 0-80 set screws http://img820.imageshack.us/img820/1082/dscn0391s.jpg I wish I would have had a sharper endmill when I made the hoist,My new camera picks up all the bad details:o http://img38.imageshack.us/img38/605/dscn0394y.jpg A full drum of cable. http://img219.imageshack.us/img219/7292/dscn0396o.jpg While getting the drag ready for Sunday I decided to drill and tap the drag jaw clutch bolts. When I'm pulling in hard it would slip because it was only pressed in. Now we'll have to watch we don't pull too hard digging because the only weak point is the motor coupling. Or it may just drag the whole machine into the pit:p Complete load unit. And walking pinion. http://img864.imageshack.us/img864/8493/dscn0398.jpg Tapered lock bushing I made to lock the gear to the shaft. http://img5.imageshack.us/img5/2779/dscn0399vp.jpg Exploded view http://img810.imageshack.us/img810/2811/dscn0400ck.jpg Bearings http://img41.imageshack.us/img41/1198/dscn0401n.jpg |
Re: 1/16 Bucyrus-Monighan Walking Dragline
Steve. Some of the finest machining I've seen in a long time. After all the time you've put in, it must give you lots of satisfaction seeing this come together.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Super job Steve
You make big progress in a short amount of time. Looking forward to your next picture post. That big gearwheel on the clutch axle is that from an lathe ?? it looks extreme good in the crane like it's made for it. And i have to agree with you on the sharpness of your end mills , but i noticed that i have never seen you using coolant fluid. It increases the life time of your end mills a lot , and also the quality of the milled surfaces. Eef |
Re: 1/16 Bucyrus-Monighan Walking Dragline
Thanks Rob.
Eef, I think on that boom hoist I was using roughing endmills and forgot to add a little material to finish now I think of it. When building it I was just hogging metal here and there to try to get it as close to the 1:1 as possible. All and all it works very well. I do brush some Cool Tool oil on as needed. The big gear is from a set of change gears I had a box full of them and used what was close to the 1:1 machine. Later on I acquired some blueprints and found that if I would have used the next finer tooth pitch (18DP) I would have been right on to scale. The one pictured is 16DP. I have been thinking about redoing some of the machinery now that I have all the blueprints but that will be later on in the future. |
Re: 1/16 Bucyrus-Monighan Walking Dragline
Here are links to a couple videos I shot yesterday at the Lakeside Sand and Gravel show. The weather was perfect. I ran the 9W almost nonstop for 5hrs and moved a huge amount of sand. I only had one breakdown with the drag rope coming undone. It was quickly repaired by a crew of guys who ran draglines and one of them spent alot of time stripping coal with a 9W years ago. If the kids wouldn't have smashed it down so many times my pile would have been about 5 feet tall. They had a great time getting their Tonka dump filled though. :)
