looks great! i must say im really happy to see the kids actually playing in the dirt, all the kids at my high school and kids at the elementary school right by use just want cell phones and Xbox... wheres the fun in that? i loved playing trucks in the dirt :D

Conveyors where built by the owner of the gravel pit about 30yrs ago for his son. It's been featured in some trade magazines dealing in the gravel business. He takes it to all of our HCEA events for the kids to play with. My kids played with it when they were little too. I didn't get a good shot of the Sauerman dragline part but it can be seen. That part takes some skill using both hands and you have to turn the cranks in opposite directions to work it. Sort of like rubbing your stomach and patting your head jumping on one leg.:D
I think Larry used to sell the conveyors and the shaker when he had time to make them up. They were 1/16th scale and matched the Smith Miller Trucks from the 50's.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve-great work as always! You have got a lot done since I last checked in! Videos looked like fun. That one little boy sitting by the dirt pile looked very interested-maybe the next generation dragline operator? Are you happy with the time it takes to boom up under power?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Great videos Steve! Looks like you had fun. The boom really looks nice.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks, Tom, The little boy watching I found out later from his dad who drives for the gravel company is a very observant fellow. He told me he sees things around the pit that aren't correct and tells him about it. Funny thing, I was watching him and was thinking about handing him the controls and see how he would do before his dad filled me in. But he told me after I packed the machine up in the van.
As far as booming up. From flat on the ground to 25deg it takes about 16 minutes. Not bad at all. I had it set up at 25deg but the way I was digging on the flat area in front ,There wasn't too much room to hoist near the fairlead.
Next week when I take it out again (I hope) I'm going to try 30deg that makes the point about 9.5'' higher,and see how that works. I want to make a miniature boom angle meter to go on the base near the operator. But for now I know the measurement on the boom to the A frame for the angle.
I definitely need to build the bucket correctly because if you notice in the video, the bucket just slides along the bottom of my cut not digging at all. That will be remedied when I redo the cutting edge and angle the teeth down. I think 23deg a guy told me who had years of experience on drags.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Great video! It's good to see the kids out and interacting at the show. The Dragline works very well. You are going to have to put an hour meter on it and see how much it runs per year;)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I bought an hour meter last winter on ebay. I just haven't wired everything the way I want it yet so it's not installed yet. It's even a tiny one:http://cgi.ebay.com/Electro-Dynamics...item1c07e4c25b

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Nice! Thanks for the link. I might have to get a couple for my dads equipment just for fun.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve-I did see the bucket sliding a little. One thing I found with my dragline is by raising the location of the chain attachment points on the bucket makes a big difference. The teeth on my bucket are not angled down enough either (I didn't know they needed to be) but by playing with all the rigging placements I was able to make it dig. I found very small changes made a big difference in the way it worked but maybe because my model is small.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

looks good you where digging like a pro there. good thing smallhall was not there or i be he would have try to get his hands on that unit crane front shoval. modelman is right about the lip angle on the bucket makes a big difference. on the real ones just by chaning the teeth angle from the adaptor out makes a big diffence. i will look and see i think we have a cad drawing of an esco bucket that you could scale.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Mog, if you have the drawing it will take a few seconds to scale with the "scale" command. Love that tool.:)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

By all means get me a drawing. I have a salesman sample of an ESCO bucket and I used it some to build this bucket only I didn't finish it yet as you can see. I'm planning on cutting the teeth off and make up a new cutting edge that may have replaceable teeth. If I had some exact sizes that would make the process way faster.
Carl, I was just playing around with the scaling function in Autocad Friday. Still getting used to ACad and really like it so far. When I drew the 9W side profile back a couple years ago, I drew 1:1 and resized to 1/16. I did that with BobcAD then,it has the same function.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That is great Steve, I always draw 1:1 then copy and scale. This way I can get more than one drawing. I have used view ports a few times, but model space is the best for me.:)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Here are a few pictures from the Brownsville,PA show last weekend. We had great weather with just a hour or so of rain on Sunday morning. I was able to move a lot of dirt with the 9W and not one breakdown for a change;)

Don't ask why Mike wanted to try to scape that mud hole out:confused:

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?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

The soil is sandy and packs when wet but not like the river sand pile from two weeks ago. Good thing the soil is sandy because over the years we get rain at the show but it dries quickly thank God.
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 :rolleyes:

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.:cool:

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

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:eek: nice work Steve :) I need 1 of those tables now how to ask mrs IH for it :rolleyes: I'm gathering more stuff for the 40 ;)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Looks like it should do the trick for you. :D I want the full size equipment besides the adjustable table:rolleyes: What I wouldn't give to have room for full sized machinery:(

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I can't wait to try next week.

I think I paid around $40 for that:confused:

May need to find a way to add on. ;)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

awsome work Hopefully sometime i can see this thing in person lol

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Just get on I70 east and come down to Brownsville,PA on the 12th. Don't forget to bring your dozers.

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.
http://img717.imageshack.us/img717/7647/dscn0648f.jpg

I want to put some eyebolts on the sides to hook a bungee cord to give the boom a cradle for a cushion ride.
http://img841.imageshack.us/img841/8995/dscn0647z.jpg

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:rolleyes:

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 :mad: hope to do it next year, this is a very fine show, I would say the best one.

Dan

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I guess I would have to make the box much heavier. But you know, you could ship the D8 over in a much smaller box so we can test it for reliability in the dirt! You could even fly over next spring and I would let you try your dozer too.:p
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
 

Hey Steve, we'll see you out there. I'm taking the fifth wheel and we'll be camping there all weekend

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Nice work steve-you should think about becoming a machinist :D :D!! That should give you good traction now. The show sounds like fun! I hope you have someone to take lots of pictures and videos!

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.
