Large Diameter Part Boring Variable Speed Pulley Repair

In this video I fix the sliding bore in a almost 24" diameter variable speed pulley. Because this is the first real job since getting the big Series 90 Monarch installed it is a little cutting action heavy so for those that enjoy watching the chips be made enjoy!! For those that don't fast forward. :-) I had some trouble in the beginning but I go thru getting it sorted and in the end the job turned out great. Thanks for watching! Tell your friends and family to come check it out too. :-)

Looks like the shop boss is back in good shape after his scrape. Nice repair.

[@radishfever]

The day we have all been waiting for. Enormous lathe action. I bet ABOM is watching.

[@SteveSummers]

Looking good Brian. The big Monarch earning its keep. That was a good job for it. 👍

[@lewiemcneely9143]

It's been many a year since I was loafing around the millwrights shop at DuPont but I understand now a lot better what I was watching then. This is what a Big Rig is for and it sounds like a twister whistle winding up! If I was there I'd take Baily off and get him right calm and give him a good ear scratching and tell him what a good old boy he is. I can do that! Might not run a lathe but I can make a pup happy. Thanks, Pal!

Getting replacement pulleys has been tough. I found Speed Selector who makes variable speed pulleys that replace the Reeves, Hi-Lo, TB Woods and Lovejoy pulleys that went out of business or got bought. Most of the pulleys are in stock or Speed Selector will custom make if needed. They have an actual engineering department who were very helpful.

[@davidfraser4830]

Nice clean job. I really enjoy the sound of that big lathe when you engage the rotation. Its like something you would hear on a large prop airplane. I would imagine you will move your other lathe into the barn soon so you don't have to go back and forth on a job like this. Thanks for the video

[@bostedtap8399]

I've used a modified drawbar to pull bushings in on the lathe, no forces are applied to the head bearings. Best regards from the UK.

[@iancraig1951]

Yeah thats a good idea

[@JBFromOZ]

Fantastic to see the old girl up and earning her keep Mate!

[@pierresgarage2687]

This makes a nice big and stable platform, Baily is back full time supervising... 😎👍 One method I use when a press fit needs to be installed, is to get the inner part in the freezer for a while, then the insert is way easier to slip in, in your case the tail stock could probably slip it in straight with enough force, got to work fast, though...

[@lewiemcneely9143]

I sort of helped a factory guy rebuild the gut-works of a cone crusher. He had a bronze bushing close to 3 feet tall to put in. He was trying to get the other guys to do it and they were scared to death. I knew the nitrogen bottle was sitting there and just grinned with him. He cooled it down and there it went. No problem. Can't remember whether he cooled the bushing or where it went but it did what it was supposed to do.

[@pierresgarage2687]

Nitrogen or CO2 are even better if available in quantity, the cooler the more it shrinks.... Just don't get caught going too slow or you'll be sorry... 😱

[@lewiemcneely9143]

@@pierresgarage2687 He had the big bottle and did this repair all the time. He said he traveled all over doing it and he was sure used to doing it up. He was a fine guy and I was the humble assistant and we had a fine time. I didn't try and tell him what to do but he gave me a good education the easy way. I like it like that.

Another way to install a bushing is to press it in with the tailstock. I imagine that one has a lot more grunt than what I use.

[@ActiveAtom]

We got beat out of being first hello Baily. These two guys could only 20.5 inch what a tough limit we could only imagine what we could do with such grand size Brian. That is a really large pulley, it is great to be here watching the opposite sized parts from our lives. So you replaced the polymer insert with a aluminum wear one, well it will not be a loose rattling one we are thinking like that old one was. Nice fix looks great as well, sturdy, thank you for bringing us along Brian. Lance & Patrick.

[@bcbloc02]

No I machined a steel slug to put in it that would hold the original poly bushing the correct size and location. None of that weak easy to machine aluminum stuff in this video. :-) lol

If we have to bore them we put them back with metal bushings. The plastic just doesn't last more than a couple years. 700 series machines went back to metal.

If you heat the bore to 130 degrees centigrade the bush will just drop in if the thou per inch rule oversize on the bush is used.

Apologies if you mentioned it, but do you know what material the polymer bushing is? We used a lot of Rulon at Reynolds and I use Delrin AF regularly now.

I don't know what it is, you would have to call the engineers at Claas, while you are at it ask them why they didn't include a seal in this design seeing as it runs in dust all its life.

Brian, can i ask you how much this large lathe cost ?? Just wondering. Thanks

[@bcbloc02]

Cost is a subjective thing. There is the base machine price, but then there is all the associated costs like moving, storage, repairs, cleaning, tooling, electric wiring and more!!! It wasn't cheap!

[@victoryfirst2878]

@@bcbloc02 I know you paid a lot for the machine. Something good has a cost associated with it. Would love to use the machine as once a machinist always a machinist. Tool and die right now does not even come to mind even though I have my journeyman's papers for both disciplines. Lathes are my first love and that feeling runs in my veins. Will never forget how to make things using the only machine that can reproduce itself. Nice to talk to you Sir. Good day too.

[@bytheseaaspirinshop801]

How is that pulley driven ? If it has a plastic bushing it must be an idler.

[@bcbloc02]

That pulley slides over a keyed hub, on the side you couldn't see there are 6 drive pins that engage the other half of the pulley and then the drive hub. This side has to be able to move in and out on the shaft to adjust so it doesn't really spin on the bushing I fixed it really just slides.
