Lots of time fooling around with these two pieces.

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


Drilling and boring


Just need the bronze bushing installed.


Hogging out the cradle


Pocketing one of the sides at an angle


Ready to turn the end pins


Roughing in one end between centers



Final finishing


Completed cradle ready for deburring and final finishing to remove tool marks.

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.

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.

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
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.

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.
