You do seem to like working on long skinny stuff. Why brass instead of steel?

This is still all the same dang piece. I've only been able to snag 5 minutes now and then to work on it.

Brass vs steel, no particularly GOOD reason. It's what I have on hand, is what other folks tend to use for these mandrels, I'm not sure how the obnoxiously expensive triple start dies will do with steel.

Two words for steel or brass.....

"SINGLE POINT"

Doesn't care how many starts.
Does a superior job.
Is totally adjustable.
Is virtually free.
Generates significant pride.
Could be an advertising feature.
Admiration of Forum members.
More fun than a pink yoyo.

I knowwwwww and I want to. I need someone to sit down and help me figure it out. It would be a MASSIVE change to my production workflow.

The " How to run a a lathe " book by south bend describes the process very well. I haven't tried multi start threads, but the process is well layed out, and is what got me over the hurdle to threading on the lathe. If you haven't picked up a fish tail gauge yet and thread gauges, do so, as they're cheap like me....
Try not to wait too long to start cutting threads, it's way easier than you think. Turn down a short section of scrap metal to, say, 3/8" toss in the appropriate gears, grind a half assed 60° point and thread it to match the nut you found in the junk drawer. Your first threads don't need to be perfect, you'll learn far more by failing once or twice than you will by "nailing" it the first time every time. Once you have your first ones under your belt, improve on them. My point being; there is no better time than the one you are in...... 😎

Golem,

The best one to sit down with you is you. You know what you want, you'll recognize it when you see and you'll always be your worst critic. Watch a video (I think Stuart de Haro has one) and have at it.

Also you need a **** it bucket, you're gonna screw up, it'll feel really good when the deposit rate drops.

Mmmm yes and no. It's a learning style thing - some stuff I don't mind diving into, some things I definitely do better with instruction.

OK, have it your way. I think Air Canada flies direct to London Ontario. I'll pick you up there, flog you till you love single point threading, and give you room and board while you are here.

@jorogi's suggestion might be faster and is flog free.

Needed a break from this stuff and had an idea for a different style of mandrel that seems to have worked out well. Nice big hogging pass here.

And finally got the new power cable management and general tidying of the area in hand. Feels better.

Setup looks great!

Setup looks great!

Thank you! This is the best this portion of the garage has felt in 7 months. Still some ongoing adjustments to make, especially re: tool storage, but it's proving to be pretty functional

 

[Jswain]

It's nice when you get the bulk of the work done and then lock in on the little quality of life improvements

 

[JustaDB]

...and then lock in on the little quality of life improvements

Sadly, I'll never reach that point... 🙁

 

[Golem Pens]

The REST of the garage... is better not spoken about haha

 

[Golem Pens]

Decided to try boring the internal diameter (of the threaded portion) on this test piece and it really improves the internal/external concentricity (no duh, right?)

Now the debate of which way to hold the work for the external shaping. I've got a mandrel for both internal and external threads, they both have their pros and cons...

 

[Golem Pens]

Still more wobble than I want but it's a lot better

 

[Susquatch]

The threads themselves don't look great.

You need to try singlepoint with a variety of hss cutting grinds.
