Hey Tom and Joe25, I see that one photo is too large and needed resized. I looked on my Iphone and it works now That must have been the issue.

Steve,

The time lapse video was one of several of my videos that got deleted but I found the raw clip and re posted it. Can't wait to see the operators station in action! When is Cabin Fever, you gona be ready by then? ;)

Still doesn't work for me steve. I usually right click and it give an "open link" box and left click to open. Now if I right click nothing shows but the "show" picture prompt and clicking that, nothing happens. Also left clicking on the X shows nothing.

This will be awsome great idea!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Took some time today to crack open the 1:1 mater switches from the scrapped Marion.
Lots of #10 wire I had cut to get these things loose from the cab.

http://imageshack.com/a/img538/7459/sK4uc6.jpg

The switches don't use potentiometers like I thought. Looks like some sort of variable transformer that changes the voltage to the control room.

Control Room. Lots of interesting things in here.

Here is another switch I have that has a potentiometer on the bottom.

My Big question is; Does anybody know what value the pots on the Spektrum DX7 Transmitter are?
I don't want to disconnect them from the radio just yet.
The plan is to hack the radio's joysticks and rewire them to the correct potentiometers that will be installed on my master switches from the 1:1 machine.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Well I took some time this weekend to strip old wiring from the 1:1 controls to start my modification.
http://imagizer.imageshack.us/v2/800...909/jiC83D.jpg

These interesting transformer things are called "Inductors" I found this out from a dragline electrician. These take 110VAC in then put out a variable voltage up to around 30VAC. These are not going to work for the DX7 Transmitter.
Pretty cool to fool around with. I hooked one up and rotated the coil with my fingers and the magnetic field increased along with the voltage output the further I turned.

http://imageshack.com/a/img537/850/oVE2QJ.jpg

I decided to unhook one of the pots on the DX7 and reconnect the wires to a 5K pot that is mounted to the bottom of another controller I have.
Well it worked! I tried it on one of my RC trucks and my dragline switch work very well. I ordered some more 5K pots to mount to my controlls now and hope to get them to work on my dragline.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Found this great on board video a guy made last summer at the Brownsville,PA show of my machine working.
This makes me want to get moving on my 1:1 controls and rig up a camera and video screen.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That is a nice video steve-It gives a realistic view of just what the operator sees. Any progress on the 1:1 controls? I have virtually real size movements on my dragline controls now and it is a little bit hard getting used to.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

No progress on the 1:1 controls Tom. I do need to work on them because they're sitting in the middle of an area of my shop just tack welded together and I need to move it because I have a big job that needs that space.
Couldn't get to working on them because real work is more important right now.
I estimate the control module will weigh more than the model, ~500#:D

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

UPDATE. Took some time this past couple weekends and got the control platform welded up enough to move it. I Haven't got a weight just yet.
Last weekend I took a trip to an heavy equipment junk yard where I knew they had an old Marion 7400 dismantled. Asked about the original operators seat. The guy had it in side out of the weather thankfully. So I came home with it.
Today I decided to go all out and see if my idea of hacking one of my DX7 transmitters and hooking up the 5K pots to the 1:1 master switches works.
Got it hooked up with jumper wires for the big test. It worked!!! Actually it is easier to control the bucket hoist chains while dragging in the bucket.
I put about an hour of operation time in with no flaws. Haven't tried dirt though only along the concrete floor. It took a little to get used to especially the swing pedals. Now I will have to take the time to wire up some of the switches on the consoles.
This is another major milestone for this long time build. I have been wanting to do this since the beginning of this project.:)

Very nice work Steve good to see you making progress on this I know you wanted to do this for quite a while. Ed

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Nice Steve .Glad you are getting the electronics part sorted out ..With a long time build like this it helps to have time to get this type of stuff sorted out ..this brings RC to a new level .. Rumor has it now that Fort mac is looking to turn there fleet of haul trucks to computer ran unmaned units ..sad when this day comes for the unemployed truck drivers
well back on topic here ..had this pics for a while now and sure you probably seen it already ..

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks you guys for the comments.

I have a question. Can my DX7 be powered up with 12VDC?
I will be hard wiring it into my control cabinet eliminating the 9.6VDC battery pack.
I don't want to cook it. The power supply in the photos is adjustable to 40VDC and I have it set to ~10V it is not practical to carry that thing along.
Looked around on ebay for a industrial power supply without much success. Possibly just look around at all the wall plug battery chargers laying around here, maybe I have a 9.6V one.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Good to see you got this working steve-that seat was a great find. Probably not many of those left. Does it feel strange operating your model with this set-up? Will this module be portable enough that you can take it to shows? If so I think a lot of the old operators would be willing to give it a try.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Tom, It's way nicer operating sitting up high. I have some cheap wheels I put on the bottom that can raise the whole platform up and be able to push around. I haven't tried them yet because I need to machine out some plates that lock the 4 wheels up. Maybe I should motorize it and make it walk.:D I was running it in my shop this weekend from about 25ft away. Didn't have a great view while swinging left to dump but it was fun to operate.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

You can use a switching BEC to get the voltage down for your radio. Dimension Engineering has an adjustable model that accepts up to 30V input.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks. I forgot about those. After posting the question I dug around my parts room and found a new 12vdc supply that can be adjusted from 7.2-13.5vdc I set it for around 10.6vdc . Haven't had time to try yet.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve-I liked your comment on making the control module walk. :D That's funny!! Will you have the full size controls ready for Brownsville?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I was even toying the idea of having it swing back and forth a few degrees but it would most likely get out of time with the model .

I think it will be ready but not completely wired the way I want it.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Hi steve-did you use the full size controls on your dragline at Brownsville and did you take any pictures.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Yea Tom. Had it out for three days. Took some getting used to. The pedals really gave my knees a work out. It is really fun to operate now. Much more challenge than the RC radio.
Here are some pictures leading up to the show.
Final welding

A little on the heavy side. Forgot to weigh after all together but,I think with the consoles it s up around 600#


I was getting some CAT grader parts sand blasted so I had them dust off the base and pedals.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve-I guess that really did take some time to get the feel. Do you find it easier to operate the hand controls when using the foot pedals. It seems like you could concentrate more on hoisting and dragging with your feet doing the swinging. Jim Brennan told me the foot pedals have really strong springs on them. I didn't see any spring in your pictures but is this true.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Using the hand controls and your feet is sorta like jumping on one leg patting your head and rubbing your stomach then in reverse at one time Tom:D

The pictures don't show how the springs are. I'll have to get a picture next time I have the controls out in the open. Jim is correct, the springs are pretty strong. My feet get numb on the bottom and my knees get a good workout.
Jim called me the other day and was telling me he is starting to convert some of his 8050 Marion to radio control. He has a 6 channel transmitter but he doesn't know much about it just yet. I really need to take a day and go up to DLW with my machine and let Jim try my system out.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

That doesn't sound like much fun steve. :eek: I think I would have a problem with strong springs but I still think this is a good idea. Jim told me he got a radio but I agree, he is totally lost. I ask him if he has hooked it up on the workbench to see how it worked and he said he didn't know how. I think he is still living in the 60's and doesn't realize how everything has progressed. I like him though-he is a great guy and I wish I knew half of what he knows about electrical systems. I told him I wasn't sure the R/C was a good idea. As big as his machines are a radio glitch in mid-swing could cause serious damage to his machine. I must admit though, today's radios are much more advanced than the ones I started out with in the 70's. I hope it works out good for him.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Got a couple picture from the Rock River show. Had a great time in the 90deg heat. Controls worked flawlessly! They got me the best dirt I have ever dug in too.

This old timer showed up and he told me that he ran a B-E 1570W for about 20yrs and he had been off one for 25yrs. I gave him a job operating and he worked the bucket perfectly. He was so pleased to be able to get back on a drag. Hope he shows up again next summer to giver it another try. I told him that this is one of the reasons for building my dragline and be able to let retired operator run it.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Time for weaker springs on the pedals?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I think that this is by far one of the most awesome Rc setups ever, and the fact that you can give the old timers who probably never ran an rc the opportunity to get back behind the operator seat is an amazing accomplishment all on its own! congrats and big thumbs up!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve,

Congrats on the operator station! I want to come try it, let me know when you are going out next and I will try to come out.

Jim

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I love watching a master in action. It's even better when he hasn't done something in a while and does it like he did it yesterday.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Steve-that picture of the retired operator in the seat just makes the point of what a great idea this is. Most old ex-operators probably want nothing to do with a tiny radio with levers, switches and buttons all over it but when they see the chair sitting between those consoles, this looks familiar to them and they get excited about giving it a try. Also, I am not surprised he did a great job. Anyone who did this for 20 years can probably do this in their sleep!! Maybe the word will get out that you have this and more retired operators will come out to the shows and try there hand at this set-up. The down side is the fact that it may cut into your operating time but I think this is a great thing that you have done. Hope you have fun with it!!
