Lots of time fooling around with these two pieces.

Profiling out one of the pillow blocks that hold the point sheave cradle.

:eek::eek: All I can say :D

That looks real good Steve you do have a talent and a lot of patients more than I in either case. Ed

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

WOW indeed!! also first time seeing that kinda lathe chuck.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:D:D:D:D:D:D I like to machine:p:p:p:p:p:p

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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

Wow! That is amazing work Steve. I hope to someday have the talent and patience to make pieces like that.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:eek::eek: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.

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Very nice work as always.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Check out some a Walter Bennetts videos on you tube
http://www.youtube.com/user/bennettshovel
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.:eek:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

:eek::D simply amazing, just outstanding

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Wow, that's just amazing Steve. It's always a pleasure to see what you've done.
That's an interesting clamb you're using. I've never seen this before. Do you have aother pic of it?

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

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Many thx Steve. Very interesting.

Re: 1/16 Bucyrus-Monighan Walking Dragline

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

So it's you who's the guilty party:D. 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.
