Wanting to learn more about lathes

I have missed your posts and photos, not only the lathes but what you accomplish with your portable machining capabilities out on the waterfront!!
I just happen to be headed to Corpus Christi tomorrow morning to align bore the shaft line on a new 86 foot push boat At John Bloodworth Shipyard. We will be there three days.

I will take some pictures as the job progresses.
 
I will be a naysayer. Unless you have a career as a machinist, forget about having a home machine shop for a hobby. Too much skill needed, that takes too many hours to aquire. Too much money for machines and tooling, that even if state of the art today, will be obsolete in 10 years. Good manual machines are getting very hard to find and expensive if you do find one. CNC machines have a lifetime of 10 years or less before the electronics puke in a non-repairable way. Picking up one and moving it is asking the electrons to revolt.

I look at a machine at almost like an artist with a paintbrush making art. Sounds cheesy but how I look at it.
Don’t get me wrong a cnc is great but something about a manual lathe to me is more dedication.
This is not for career but pure hobby
Don’t get me wrong would be awesome to thread my own barrels or small projects but something to learn and learn new skill

I would say that probably depends more on the personality of the person involved than anything else. Some people just can't stand by and let someone else do everything for them.
But, if all you are going to do with a lathe is chamber barrels, I would almost agree with you. However, once you start using a lathe, the utility of the machine is never ending.
I can't think of any other tool in my shop(and there are lots of them) that has increased my capabilities like my lathe. I use it for everything.
 
Any person with a reasonable amount of mechanical aptitude that understands the concept of why you do things can certainly master the tasks involved in chambering barrels And performing other machining operations that are within the realm of a small “hobby lathe”.

Through the years, I have taught quite a few young men basic machining skills, several have been with us for close to 20 years.

I am training a young man now who has been with us a little over 2 years. He is learning quickly.

The basic concept that I instill in all of our men is while it is important to know how to do things, it is just as important, maybe more so, to know WHY you do things.
 
There's a principle I learned many years ago as a young missionary called OYM. Open Your Mouth. Just bringing up a certain topic in an ordinary conversation can sometimes create opportunities for you. Not too long ago I was interested in getting a lathe but didn't feel like I could afford one. I had begun learning on YouTube (Joe Pie, This Old Tony, Cutting Edge Engineering, and other channels), I had researched tooling, and even practiced a little on my buddy's lathe. Then one day I was doing a job for somebody and I mentioned that I wanted to get a lathe. He said, "Why don't you buy the one I have in storage?" It was a Chinese made Jet 14x40 that had a broken compound. After taking a look and assessing the repairs we agreed on a price of $500. It came with a Newall DRO, a Dorian tool post, Jacobs drill chuck, and various cheap chucks and face plates. I was able to fix the compound for about $100 in parts and a few hours labor. It is far from being a top quality machine, but its great for learning and its capable of making good parts. Keep opening your mouth and eventually you'll find the right connections.
 
Anyone who has looked at one of my amateurish You Tube videos, knows that my home shop is very modestly equipped, yet I have been turning out reasonably decent work for nearly fifty years. I am largely self-taught and learned by reading, watching, and listening. What I have learned over the years is, the more you learn, the more you can learn. In other words, once you begin to accumulate a base of knowledge, you develop the ability to add more. Soon, you are able to think creatively and problem-solve on your own.
One fellow I knew was a Ford mechanic who was also a gun enthusiast. He bought himself a 6" Atlas lathe at a pawn shop, for about 150 bucks, as I recall. Mick was a very accomplished mechanic, with a good understanding of how things worked. He bought a 45 caliber, 1 1/4 inch barrel blank. About a month later, he came in with the barrel which he had contoured to match that of an 1886 Winchester he was resurrecting. He had done this by mounting the tailstock of the little lathe on his bench and turning half of the barrel. He then flipped it around, offset the tailstock in the other direction, and turned the other half. He threaded the barrel and chambered it to 45/70. Maybe 25 years later, Mick had retired from the Ford dealership and started making barrels. He didn't get to make a lot of them before he died, but those he made were equal to anyone's. Mick learned the same way I did. He read, he watched, he asked questions, and he listened. He knew what good work was and took the pains to do it.
A Lathe is a pretty basic machine (or it can be). A person starting out doesn't want to get into the trap of thinking he NEEDS everything at once. What he needs is to establish a base of knowledge, on which he can build. Also, a person never wants to avoid what might be a very rewarding pastime because it's going to cost money and require some effort. WH

Thanks! You are truly a master. Line boring especially the big jobs is beyond me.

Ah Corpus Christi. Visited often when I was stationed in San Antonio. Loved Padre Island. Caught a few Red Drum surf casting there.

Well, I got back to my Shop this morning. The Job went great.

here are some pictures I took. Keep in mind, this new boat has been sitting in the channel for about a month. The finally got her on Drydock to finish all of the underwater work.

The first pictures are me Laing out my witness marks off of the .031 wire. The wire is ligand dead center with the foundation and inboard seal mount. I then set my boring bar up to the witness marks and bore.

in short, what I am doing is mounting the boing bar in the exact same location as the wire, then boring the holes to 10.5 inches.

As you can see, I mount and bore with two bars at a time. The one in the strut is our 3.5 inch x 6 foot long bar, the one in the stern tube is our 4 inch diameter 14 foot long bar. You can see the inboard support bearing mounted in the seal housing mount.

Just buy a lathe. Read books or watch videos, try something, make adjustments, repeat. Add tooling as needed.

I agree with what jackieschmidt said, "reasonable amount of mechanical aptitude" is all you need.
