1/16 Bucyrus-Monighan Walking Dragline

I have to agree with everyone. Everything you make is a work of art. Way beyond anything I have made or hope to make. I am humbled by your skills.

Amazing work steve!! That looks like a really tough pc. to make. I'm glad it's you instead of me doing that. I never really understood how the point sheave could swivel from side to side until I saw these pictures. Now it makes sense.

What a piece of art, no , every piece you make is art!!!
Got to go to Brownsville!

Many thanks you guys. I've been waiting a long time to make this piece. The drawing in the parts book I designed it from has really good details of it. I think I'm pretty close. The only other alternative is to go climb the boom on the real machine and measure.
Next step is to work on the sheave and front bearing block similar to the rear one only the top is chopped off some.

Very nice work as always.

Thats interesting how it has the sheave trunion mounted. I guess you have to worry about side loading alot more in a drag line than you do in a crane. Your machining skills are excellent. I'd love to see this thing in person sometime.

Check out some a Walter Bennetts videos on you tube

I talked him into putting his mining videos on youtube a couple years ago. Watch one of his more recent ones with the Marion 7820. That operator is already swinging just before he pulls the bucket out of the cut. The bucket is practically behind the boom tip most of the time. That machine has I think, a 300' boom on it with a 40cy bucket installed. This is why you want the point to swivel.

simply amazing, just outstanding

Wow, that's just amazing Steve. It's always a pleasure to see what you've done.

Hello Lorenzo. That clamp is called a lathe dog. This is how you drive a part while turning,grinding or milling between centers.

So it's you who's the guilty party. I gotta say thanks for doing that because I watch every one of his videos and I love 'em.

This machine just gets better and better.

Another few hours. I still need to pocket out the spokes on the sheave but I have my mill tied up with a job.

[Dreamweaver]

WOW looking good, Must be a thing about Guys named Steve and machining ability.

I'm jealous, sure wish I could do that... Should have actually went to my metal working class in high school.

This is a very impressive machine Steve, good work.

[lorenzo]

Many thx Steve. Very interesting.

[mog]

very nice work there you take grate pride in your work and show's 10 fold keep up the good work my friend.

[pugs]

I see I'm not the only one to use whatever tool works to get the job done.

I was going to comment on that .046R cutter but I see you have a good eye.

that makes a true machinist

[tc1cat]

More impressive machine work from a master. I know what you mean about using whatever works. I very seldom use a boring bar unless I need to go very deep. 2 flute end mill works very nice as a boring bar. Maybe I should be quiet Giving away secrets!!!

wow that looks good!
