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.

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?

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

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.

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.

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.

Roughed in pieces:


Cutting a 45deg. bevel:


Beveling the ends:


Attached with #1-72 screws:




Ready to walk again:

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

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.


I want to put some eyebolts on the sides to hook a bungee cord to give the boom a cradle for a cushion ride.


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:

Nice box, guess it can be used shipping the machine abroad

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

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.
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.

Adding some pictures of my machine to this thread I have elsewhere on the forum.
Aerial view from the D9G




I clamped my camera on where the operator's cab will be to get an operators perspective.



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.

Like the operators perspective.

Thanks for posting them Steve.
