OP seems to have disappeared. That's really too bad. I don't think we were harsh, but somehow he wasn't ready for our style of help. Is there a better way of handling folks like this, or do we just accept the attrition rate? Serious question.

I think that was his style.
I have the same machine and chimed in with my real world experience. Hard to say if it could have been handled differently. Maybe if no one said anything expect those with the same machine? Dunno.

lol, I think it was handled fine. Some people you just can’t reason with

I see in previous posts by the OP that he was experiencing poor turning results after completing a motor transplant on his lathe. The OP is looking for a simple answer to his original question. Fair enough. The problem is that a simple answer is virtually useless as there are so many variables which affect the results. Perhaps if he received a thousand simple answers, he might be able to plot out the results and determine a most likely answer.
I believe the members who replied with their different answers to his question realize that and attempted to list some of the variable that affect successful use of a lathe. As others have posted, the best approach is to do some experimenting with tool geometry, depth of cut, surface feed and spindle rpm to see what works best for him.
Some other machining forums tend to get rather snarky with their responses. If one looks at the history of this forum, it was started with the intent to avoid such behavior and for the most part, it remains true today. Members are genuinely committed to helping others. It is the reason that I have been a contributing member for nine years while rarely, if ever, even visiting the other sites.

Well over 90% of my finish problems have been attributed to the tooling, either a chipped insert or chipped or fractured HSS. All I know is if I honed the tool, or replaced the insert, better than 9 times out of 10, the problem would go away. But this is with a somewhat sorted lathe. I make no claims to being an experienced machinist, but occasionally I can make some decent parts. My experience with a mini-lathe taught me to take nothing for granted, check everything. It is only after you checked it yourself (perhaps testing one or two different ways for some things) that you can rule out "that problem".
The chips or fractures were invisible to my eye - I only could see them at 10X magnification. I can see that someone who hasn't machined much getting snookered by this, searching for other less likely causes. This is not to say that there aren't lots of things that affect finish - there are.
My approach to this is to check out and do the easy stuff first. Hey, it might fix the problem, and you are done. If not, look at or rule out the next most likely issue. And so on. What makes it tough in cases like this is we don't really know the condition of the machine, or even if the fasteners and belts are tight. When folks get testy about checking these simple things (the most likely suspects) it's hard to get much progress. Maybe if we spelled out the methodology up front, there wouldn't be as much resistance. But I'm with @DavidR8, dunno...

I have a BusyBee version, a DF-1224g of that lathe. I bought it used with a RF-45 mil/drill together off a cabinet shop. It was for some design he was doing. I only paid $1750 CDN for the pair. They were not pristine, chuckle. The belts needed changing. Being a retired millwright, I had to change the bearings too. It's second nature for a millwright. To change the belt/bearing I had to pull the headstock apart. The bed is a Colchester clone, but that headstock is a genuine Taiwanese Generic . It's a pretty light casting .
But having said that, I'm hitting within a couple of 1/10ths, which is the clearance I put in the Timken bearings. That's the lathe because it certainly is not me.

I have a similar lathe and saw the post when it first made. I chose to not reply because of the nature of the question. Could have said I can take a .030" cut but it's honestly kinda irrelevant.
As those with way, way more experience have said - your machine, your setup, your materials, etc.
If you come here to learn you should accept all answers to your questions. Answers that miss your point, or give you info you already have, or are about something else entirely are not unusual and are rarely done with any ill intent. I try to click "like" on everyone that responds to my posts because even if I don't see any immediate usefulness in what they post I might later and I appreciate them taking the time to respond.
The OP has already stated in other threads that he doesn't have a lot of patience so not really surprising if he lost patience with us
Some folks ya just can't please though, mama said to "bless them and send them on their way"....
