Lots of time fooling around with these two pieces.

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

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!

Me too!

Thanks for sharing!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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?

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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
 

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

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.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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.:(:rolleyes:

This is a very impressive machine Steve, good work.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

wow that looks good!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

that makes a true machinist ;)

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

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:rolleyes::rolleyes: Giving away secrets!!!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

You did it again Steve, You made me absolutely speech less :). Amazing work. The only thing that's sad on it is that I prabably won't see it IRL :(.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

We like secret's! Thank's for sharing. Later, Neil#2 aka doodlebug.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

More photos of the point progress. I didn't get as much done as I wanted due to some flu that's going around my house:(

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Looks really good steve!! Can't wait to see it all put together.:cool:

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

I want to get this part together too. I need to mill some off the ends of the boom chords so the channel that holds the front pillow block sits perpendicular to the centerlines of the taper. I probably could have got that done but I friend stopped last evening to check my progress so we BS'ed for two hours. Next step is to make the 19 sheaves for the suspension ropes.
Hopefully I can get it ready by next month because I want to take the drag to a show.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

nicely done so much detail wish i had the skills of some of you guys

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Just wow. That's looking really cool. It looks so good that it would be a pity to hide it under a coat of paint.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Everytime I checkout your thread Steve I don't know what to say ! I have learned alot just looking at your photo's, keep them coming.... Great work

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Thanks again you guys. I've been laid up with the flu this week but today I decided to come to work for a while. Nobody knows what to do when I'm gone.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

lol gotta love that!

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

Always GREAT work! What show are you trying to get it done for? I really need to see it in person:(

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

May 6-7-8 2011 International Watch Fob Collectors .http://www.watchfob.com/show.html near the Cleveland Airport . One of the leaders has a open house at his gravel pit on Sunday only.(Not sure if it's open to all.) Near Mantua,Ohio. The pit is real close to the turnpike and if you know where to look you can see part of his pit. Operating 1:1 shovels draglines,dozers, loaders and other machinery. I want to take the dragline and set it up in his shop and dig some sand and gravel. I was trying to do it last year but it rained that weekend and I was still tacking the bucket together and didn't make it.

Re: 1/16 Bucyrus-Monighan Walking Dragline
 

fire him off an email. worst he can say is no.
