Now for the fairlead sheaves..
I used the same fixture for all three different size sheaves Almost finished Hollowed out are for side sheave clearance. [IMG]htthttp://img509.imageshack.us/img509/69/9wmodel038jo7.jpgp://[/IMG] Boring the wheel for bearing Almost ready to cut loose. Drilling the mounting holes for the guards that protect the wheels from the crows foot jamming back into them. I still need to figure out how to machine them. |

That's 1018 cold finish steel. I had that laying around and it looked like it would work. My only regret was,I should have squared the piece up some because when you get to that size it maybe out some.

Re: 1/16 Bucyrus-Monighan Walking Dragline
I finally have a little to add. I decided to order the required tubing needed for my boom. Here's some of the 120' of 1/4''&3/16'' round tubing I'm using for the boom lattice work. I'm still waiting for the 5/32'' that's coming from another location. All in all, another $200 into the dragline.

Re: 1/16 Bucyrus-Monighan Walking Dragline
Should look really good with a proper boom on it. Can't wait to see how it turns out.

Here's a drawing of the boom but some small changes and details still need to be ironed out.

Re: 1/16 Bucyrus-Monighan Walking Dragline
I've been trying to get my brain started and try to remember where I was on this part. The Boom hoist. I trying to get the right motor with enough power and output. Right now it's way too slow. If my calculations are correct it would have taken 55 minutes to boom up That's just not going to work.
Sorry for the BIG pictures |

Very nice work steve! I remember this from the garden site but I don't think it was finished. Did you cut these gears?

Very nice steve! I don't understand the monitor thing or the brass plates, but I like the work it's doing! Be interesting to see the finished parts.
