SNS 366: Machining New Stub Shafts, Sprocket Repair

[@erneststorch9844]

I had a similar job for my buddy . He bought a used asphalt roller that had a worn out drive sprocket. He found a new sprocket that was exactly the same except the bore was 1" and the roller shaft was 1 1/4". I bored it out to 1 1/4" and broached a new key way. He was sure glad to get it.

[@hdfanboy]

Great video as usual. One thing I always highly recommend to the guys when I train them on cnc is get a notebook and write down everything step by step so you have something to go back to. No one gets everything right the first time and until you use cnc daily your bound to forget stuff so having it written down so you have something to look back on is a huge help.

[@marcusa3911]

Exactly! Notes notes and more notes.

[@russellstarr9111]

They really got all the good out of those old shafts and the sprocket bushing. It's a miracle they didn't have a catastrophic failure.

[@paulcopeland9035]

I'm familiar with that type of roller equipment. RPM is maybe 10-15 max. "Catastrophic failure" would be a lot of rattling!! I am guessing those shafts reached "catastrophic failure". It is amazing the amount of wear that certain industrial equipment is sometimes asked to operate with.

[@BruceBoschek]

Love that PM lathe. Quiet and solid. Very nice to have that top-down view of grinding the radius. Those are the things that are really helpful for us beginners. SNS rocks! Thanks, Adam.

[@tomnekuda3818]

Watching you set up and get you machining right on the money is one of the most satisfying and restful uploads for me. I used to ride/race Husqvarna motocrossers and lived out in the boonies of Wyoming. I had a good friend who taught machining at the locat 2-year college and he used to make pieces that I could not get in time for a race for me. Sometimes I would compare them to the actual part from Husqvarna and his pieces would fit better than the dealer. Hell of a machinist he was....he taught me a bit and I asked myself, "Why didn't I go into that?" Thanks for your uploads.

I stumbled upon your videos several years ago and have watched faithfully ever since. Never did any type of metalwork prior. I asked my wife if she could think of a reason why we would need a lathe. Of course she said no. Needless to say I found an older Rockwell/Delta (11x36) at auction from a local machine shop for $600. After refurbishing it (electrical, scraping, paint, etc) I sold it for $2900 and bought a LeBlonde lathe (18x58) and did the same. Sold that one for $6200. My goal is to buy a new one, all thanks to stumbling upon ABomb. To say I’ve had fun doing this is an understatement!! So thank you Adam.

[@mfc4591]

Nice job Adam. I like the way the shaft fitted the bushing even after it was pressed into the sprocket.

[@Garth2011]

Those used parts sure are long ago worn out. Seems that they need some harder metal but I have no idea how many hours they have on them now, likely tens of thousands. Those custom jaws on the Wilton are what made that job work so well vs. old uneven and worn jaws. Nice. Computer run equipment will rarely make a single small job worth programing which this video simply proved. Computer work is great but the time to program has to be taken into consideration when figuring out total investment time.

[@AlejoMX5]

That’s the problem of learning a new way of doing the thing you’ve been doing your whole life. CNC has a steep learning curve if you already have knowledge of doing it manually. You basically researching your brain to do the same thing differently. Keep at it, Adam.

[@kamper4140]

The ability to do radius cuts on the cnc would have been worth it to me, but if you had to hurry and get that out can't blame ya for sticking to what ya know. I just got a proto trak cnc mill that is conversational and it's pretty cool being able to just program the actual geometry not the toolpath. In a month I've gotten to where I wrote a program to make a weld on pin flag put of 3/8 plate in about 10 minutes. Being able to cut circles and complicated profiles on the mill will make life much easier even in a job shop. I suspect you'll feel the same way once you get the hang of it. Cnc will never replace some manual work but it can make some manual work much less complicated.

Adam, yes although you are confident with manual lathe it would have more value if you force yourself to use and learn the cnc. Using those shafts as practice later is a good idea too. Once you do it you'll realize you could have done it just as well on the cnc as on the PM. I worked at 3 cnc machine tool companies and it was difficult helping the machinists convert to cnc.

Hey Abom, using carbide insert profiled for aluminum work really well for lighter cuts on 1018 if you want great surface finish. Obviously they wear out much faster than steel profile inserts but they still last quite a while(especially TCMT with the three cutting edges per insert).

I have a hard time using my cnc on projects that I am so comfortable with doing manually. I find using the cnc that it easier to forget how to do something than to learn something. So it is a tough learning curve. However if you are doing a lot of parts you can’t beat cnc once it is set up.

As a plumber we use emery cloth to clean copper but we also use grit cloth witch is basically like a screen door it lasts forever it would be interesting if it would work on steel

Open mesh is also a joy to use on wood. I feel ordinary emery cloth doesn't really clog with steel though.

[@Toms4speed]

For the CNC lathe and simple stuff I'd recommend a program template for you. Copy and paste then renamed. Has all your cycles in with preset safe starting numbers. All you change is profile code. Still involves all the math you use on the manual lathe. More hands on where you would feel familiar. Much less point and click memory.

It absolutely boggles my mind that I work in a facility where there are MECHANICS who have no idea how to do the simplest of things. Adjusting a grinder tool rest so that it's the proper distance from the wheel. NOT using the grinding wheel that is meant for ferrous metals to grind aluminum, brass, and plastic. Using a wood cutting band saw blade to TRY to cut metal. The list goes on. And it's not just new guys doing this. People with 20+ years on the job doing it too.

[@agdtec]

I know you are still learning the CNC but one project that seems easy to design is the custom cutters like the one you ground to the radius. I am more used to designing stuff for 3d printing but the concept is the same. Once you make a model for a radius tool all you have to do is pull up the original and change the radius and save the new file under a new name. and I know you have done several different geometries that you have custom ground in the past but going forward you could just build a library of various profiles. There might even be libraries on line for that type of thing in the user groups for your machine.

[@jennitro]

A bit of a Catch-22 on the CNC lathe. A project like this probably doesn't benefit from its abilities and, as I believe you said, you can knock it out much more quickly manually. But it's exactly the kind of stuff that you almost need to do on the CNC just to get comfortable with it.

I ended up buying a new Skoda and I've been very happy with it but I would still like to get the Royal reground as a back up. I've looked around and seen a few third party places that recondition them but haven't gotten around to having it done.
