Cutting threads on outer barrel

[krap101]

Hey guys, I've finally found a 14x1mm ccw die, and I was wondering how to cut the threads correctly (perpendicular). My first try led to crooked threads.


Thanks guys!

A lathe helps.

That makes sense :P. I have few tools on my "need to get" list.
#1 - DCD970KA
#2 - Drill press
#3 - Router
#4 - Lathe

and I'm sooo broke ><

Also might want a tool to help calculate the center point of the object on the lathe. Forgot what it was called, but it's similar to a cube cut diagonally in 1/2 with the top part exposed to help mark center points. Really important to have if you are going to be buying a lathe.

Where did you find the 14mm CCW Die?

Started looking briefly on the net and found some place you can pick up the thread starter which will give you proper alignment and distance for the threads.

Helstrom you might want to check it out too since they are selling the dies too.

Cool, I'll check more into it after finals ><

If you had a lathe....you could make your own die starter......

Buy a lathe first...

Right now I'm looking into like a 200$ or so mini lathe. Is that a bad idea?

[m102404]

There are mini-mini lathes...like the Taig/Sherline. Those are/can be very accurate. But capacity and through spindle size are very limiting (for anything but miniature pieces). These are small footprint, lightweight things. You can fit them in a tool box.

There are "mini-lathes" that are typically China made 7x?? (i.e. 7x8, 7x9, 7x10) lathes. The accuracy is (IMHO) good enough for a lot of general stuff...but not good enough for really precise work. There's limited fine tuning that you can do the machine...so what you get out of the box is what you get out of the box. These are bench top machines where you need 2-3' of space...and while they're portable (as in you can pick it up and move it) they're usually left where you put it down. Through spindle are capacity are ok for most things...but not big/long enough to do a outer rifle barrel. But within their capacity they're great....for example, cutting down and recrowning an inner barrel is a snap, making a barrel spacer is dead simple, etc... You can make decent steam engines too.

Then there are "real" lathes....bigger, heavier, $$$$$. Think 6+' of working space and hundreds and hundreds of pounds.

There is one sure thing....no matter what you get...you will want a bigger machine eventually.

Size does not necessarily reflect accuracy. $$$ does typically reflect quality and accuracy.

I bought a 7x10 lathe. Due to space constraints I don't have room for a bigger lathe. It'll do 80% of what I'd like to do. Ran about $600 here...it's definitely cheaper in the US. Check Harbor Freight for the pricing.

My gift to myself after I graduated.

Sadly I live in an apartment so this bad boy lives in the closet.

But I get to use the bigger ones at work so it is ok.
