Steve,

You got it all back together, ready for Cabin Fever right? See you in a week.

Had to order another 2000 0-80 socket head caps screws.

A frame going back together. This part still needs several angle braces added. That will come later when time permits.

After about 16 hours got some more assembled. Not painting any brass parts yet. There is not enough time to get these parts done either

Boom attached just had one heck of a time getting the suspension cables untangled.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Looking good Steve-I see you are giving Walter Bennett a challenge on most bolts used (rivets).:D I think I see a brake band on the rear drum. Is this a work in progress? Nice job!!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Brake band is in progress. No time right now. This was one of the reasons for the tear down. Now I have the machining done on the main frame to attach the necessary parts. I was going to use servos to actuate the clutch and another to set the brake. Changed my mind because I think a servo will burn up if the clutch doesn't shift exactly as it should without binding. And if it binds, I can't hear or see it with all the outside noises at shows. I am experimenting with some lineal and rotary solenoids.

Came across this video today of the first time out with my new Marion controls.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Decided to spruce up the bucket with some red paint to resemble the ESCO bucket I duplicated some before this weekends "Big Dig" at the National Pike Show. Last time out at the Cabin Fever Expo, I had trouble seeing my bucket with the lighting there. There are still wear plates and better teeth that need made on this bucket but that will come some day.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

After years of searching I picked this little gem up this week. It took a long time to find just one but now I have two. One for each side of the boom.:bounce:
These are actual porcelain enamel signs Bucyrus-Erie had on their Bulldozer cable controls from the 1940's - 50's

SWEET You lucky boy. Now it's Perfected. Looks awesome :)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

The bucket looks killer with some paint on. Did it help visibilty as much as you hoped?

But those signs are way over the top cool!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

The red bucket was much more easier to see. Shows up better in pictures too.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

The model is pure awesomeness in itself, but the signs and red bucket really do add something. Nice touches.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Haven't looked at this thread in awhile and wow great work! I wish I had that good of a detailed bucket for my dragline build!

Question what are your motors running rpm wise, im trying to size my motors for my Marion 8750 and having a hard time figuring that out on speed and torque needed. Thanks!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I used the technical data from my machine's spec sheet to get the feet per minute from each function.
My motors are:
Swing-2500rpm 1/17hp 130vdc
Drag- 500rpm 1/12hp 130vdc
Hoist 417rpm 1/29hp 130vdc
They are geared down to approx scale feet per minute through the gearing. The drag is too fast so I have the max rpm turned down.Someday I want to build the gearbox for the drag correctly using all the gears exactly like the 1:1 machine.
I can also change my speed by changing the stick travel with the limits on the DX7 transmitter.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

It has been very hard to find any time to focus on this due to being busy at work all the time.So I found some time to do a little work on my 9W before Cabin Fever. Since it was very hard to see last year at the show I painted the bucket last summer and I added some lighting to my boom. I bought these bolt LED's and turned them down to fit inside of some old Lionel flood light housings.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Well I found a little time to break out my model again and get to some more parts that need made. I decided to make some roof trusses and get some cover on this thing.

I made a simple fixture to machine the "T" bars since you can't buy the size I need.

https://imageshack.com/a/img921/3517/bfdCrg.jpg

A little scrounging around and came up with a cutter stack to mill these with a .040" web and flange.

Four cuts to depth and they turned out nice. Bigger cuts caused some problems.

https://imageshack.com/a/img922/3466/YXBdFC.jpg

A few ready for next step

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I LOVE the light idea. The "T" bars look good too.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Got some more TEE made now bending the trusses .

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I love them roof trusses! Makes me wonder if the technique you used could be used to make a bridge structure.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Haven't been able to get on here for a while. Wow, great progress! Only problem I see is, no one will be able to see the great workmanship inside if you get it all covered up.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That has been plaguing me for quite some time.
Some people ask me ; "When are you going to put the skin on it?" and some like to see the internals.
My plan is to make the house but also make it removable on the left side.
That way I can show off the machinery and be able to see if the wire ropes get screwed up . The operators cab is on the right side and that will need to be attached securely.
I hope to have scale operator in there with the controls working in unison with my movements on the 1:1 controls and some of the red and green lights on the control switches working as well.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

AWESOME job! I just picked up your post and now I'll make sure I check back!

-Terry

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Roof trusses look sweet.
If there's a scale operator doing the controls, it's going to raise the question if you're controlling the machine, or if the little guy is controlling you.

Hey Steve-sometimes I can log on here and sometimes I can't. :confused: But I will keep trying. Your dragline looks better everytime I check it out. Good job!!!
