You can accomplish a better finish without changing the feed rate by using a tool with a larger nose radius. Tool shape and nose radius are as important if not more important than feed rate for finish quality.
I agree. I do have some cutters with a larger nose radius. I do use them. But they limit the depth of cut too. I see both sides of the debate. Thanks for watching!
Both your video and one with the Craftsman version of the same lathe have quick change gear boxes. Is there any reason the gear swap won't have the same result without the quick change option?
If I’m reading your question right, the lathes without the quick change gearboxes work primarily with the change gears. It would be a matter of reducing the ratio of rpm on the feed screw. I am not familiar with that style of Craftsman lathe enough to say for sure, but I know the spacing is limited and you may not have the room for the change. This would be an excellent question in one of the forums on Facebook or other SM.
Great idea. Where did you get the 24 tooth gear.? What is diametric pitch? If you give the diameter of the gear, I can do the calculations . Thanks Frank
I bought the gear from eBay. Not sure about the pitch at this time of morning, but I will look. I do want to learn gear cutting. I have all of the necessary tools, just haven’t gone down that diametric rabbit hole hole yet.😅
Look for Mr Pete 222 on RU-vid. Shop tips 192-200. Great tutorials on cutting gears. He has a whole series on the Atlas lathe as well. Best wishes Frank
@@odd- mine runs on 220 single phase with a converter, commonly referred to as a VFD . The comments on surface finish are correct ( tooling ) makes a difference however for single point threading the speed does need slowed down in my opinion.
@@odd- I think mines a 2 HP baldor. Fits just fine no modifications I’m aware of . I was lucky I had the converter I found at a thrift store for 25 dollars and it worked . Lenze
I do know the wider radius on the cutting tool helps, but this set up takes it a little further. On top of that, the motor that runs the lathe is in need of rewinding. It is weak to say the least. This helps with that issue too.
I appreciate your feedback. I’m a new creator and trying to make the videos interesting as well as educational. It’s a work in progress to say the least.
