1/16 Bucyrus-Monighan Walking Dragline

[D8R]

Steve, what I ment was it´s a shame to cover all this beautiful machinery covered up with sheet metal. You have put so much work into it so it has to be seen. Maybee a removable roof?
Here´s a pic from HCEA2008
It must have taken lot of hour milling out those sides


is it same type of control on the drums as this old model but with r/c servos?

Oh, I'm going to cover only half of the machine-The cab side. Yes I'll leave some of the roof open and the left side and I'll have lighting inside. I still need to make the big supports for the walking bearings that go into the roof and I have to make the curved roof trusses. The 3 motors are controlled with 100VDC regenerative drives similar to the 1:1 but solid state. The rc part was a real learning experience. When I have all that 100% I'll show more detail on that. I'm still on the trial and error method I'll have to post some of my progress from this past weekend on the boom.
I would love to have that stiff leg derrick toy that guy had at the show. I forgot to take some pictures of it like you did.

Looking good Steve!

Great idea on the fixture to make it.
