Re: 1/16 Bucyrus-Monighan Walking Dragline
Now it´s clear why you had to spend a lot of money on tubing. Very nice piece of work, guess I have to visit you next time in us to get a crash corse in brazing!
Do you have drawing for this or did you have to climb the mast to get all meassurments needed? Dan |
Re: 1/16 Bucyrus-Monighan Walking Dragline
Interesting way of linking all the parts by notching and soldering. I'll keep that in mind :).

I have some drawings provided by Walter Bennett of Scranton,PA. He built a 3/8th'' scale 10W Dragline between 1967-1980 and has several photos and measurements he took back then. In his collection he had a set of photos and drawings dated:March 1969 that were of a 9W boom that he made by mistake thinking it was the same as his 10W. They are fairly complete but I still had to design it by referring to his photos and drawing and use my imagination alot. I have some drawings of my own of the point and I'll get to that I hope this winter. Lorenzo, The notching is exactly as the real machine and all the pieces are sized almost exactly as the real machine. |
Re: 1/16 Bucyrus-Monighan Walking Dragline
Do you use an apaerature to hold all pieces in position while soldering or is the tension of the parts doing a good job?

Now you're talking about I remember (I'm getting old ;)). Maybe you coud use a cooking plate to pre heat the fixture and the brass parts.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Smallhaul Scott, I finally pulled the drag out of the crate after 4 months this evening and hooked up my new Spektrum DX7. It seemed to work flawlessly on the swing and drag. I didn't put the temporary boom on yet to see the real pain," The Hoist Function". I'm sure it'll work fine too. I was fooling around with the dual rate and figured out how that works. That will come in handy for a beginner or possibly aid in truck loading. Another would be,if there's enough torque on that low of a setting, "Walking"
I am getting ready for some soldering work this weekend and hopefully have the first boom section done. |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Lots of progress this weekend. Almost all of the tubing is soldered together on the first section but ran out of time. I can't wait to be able to pick it up from the jig and hold it without worrying about it falling apart in my hands:D
I can't take any pictures yet because my camera is not working properly. I'm in the process of buying a new one now.:confused: I'm thinking about a: Nikon S8100 |

Re: 1/16 Bucyrus-Monighan Walking Dragline
Well, I got all the tubes fitted and some soldered but will finish this evening. I went out and got my new camera and I'm trying to get used to all the new gadgets it has.I need to get it set correctly though. Here are some pictures of the boom in it's jig to hold the taper correctly.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Looking really good steve! Are you making the boom so it can be partially dis-assembled?

Re: 1/16 Bucyrus-Monighan Walking Dragline

Re: 1/16 Bucyrus-Monighan Walking Dragline

Re: 1/16 Bucyrus-Monighan Walking Dragline
Thanks everybody. Tom, I'm making as close to real as possible and it will come apart. Maybe I'll need to haul it on a scale lowboy:D.
Well now I've reached another mile stone. The bottom section is now complete out side of walkway and light brackets of course. When I took it out of the jig I was totally impressed how strong this thing is! I just had to mount it on the machine to see how it looks, and Henry can now see how big this is getting. Please bear with me as I haven't got the new camera figured out yet.:confused: http://img87.imageshack.us/img87/9937/dscn0043qv.jpg First time on! http://img403.imageshack.us/img403/6776/dscn0045s.jpg http://img816.imageshack.us/img816/7594/dscn0048v.jpg http://img42.imageshack.us/img42/8535/dscn0050f.jpg |
