I've been messing around with it some, But I have no owners manual, and really want to learn how to do threading! You can kind of se my tool holder in one of those pics, what all do i need to get to do threading? and, How do I read those tables and adjust the speed and stuff?
 
cool....

I may be picking one up thurs... sorry, no real help... :o
 
I started by messing with all the dials with the late turned off. It was like this...."Hmmm, when I turn this dial, this happens, when I spin this handle, this happens."

Buy this book:

http://www.brownells.com/aspx/NS/store/ProductDetail.aspx?p=18158&title=HOW%20TO%20RUN%20A%20LATHE


This is another great book:

Single point threading is a process that takes some learnin' for sure, but it's awesome as hell to thread a piece correctly and have a nut screw right on. Both of the books I mentioned should cover it in detail. You are gonna wanna ditch that lantern tolpost and get yourself an interchangeable toolpost. I have a KDK toolpost, and I like it a LOT. Quick change toolposts save you a lot of setup time when changing tool bits.

That indicator scale lets you know when to close the half nuts when threading. To do different thread pitches, you put the A-E and 1-8 levers in their proper hole according to the on top of the gear box, it probably says "threading chart" on it. You will learn all about this stuff, including grinding your own HSS lathe bits in either of the two books I mentioned.

You should mess with the levers on the cairrage a bit. One lever will be a selector, that will select how the cairrage or cross slide moves when you engage the clutch, which will be another lever. Move the cairrage to the middle of the bed and turn the lathe on, mess with the levers a bit. Se what happens. Don't force any levers into position. Don't close the half-nuts with the clutch engaged.


Whatever you do.....Now listen to me here!!!!!!! Never leave the chuck key in the chuck if your hand is not on it!! Not even for a second!!!! If you ever get that chuck key whipped into your face, amidst the bleeding, spitting out teeth and/or unconsciousness, you'll remember that guy on the introweb who told you to never leave the key in the chuck! All of this is but the tiniest smidgen of what you'll need to learn to get the full potential from your lathe. Oh, yeah, order a catalog from these guys too:

Start saving your money, lathe tooling, even used, does not come cheap. Well, it may be super cheap compared to the price of 'new', but it still ain't cheap! There used to be a lot of good deals on ebay. Enco has monthly free shipping promotions for orders over, I think, $49, maybe it's $99, but free shipping is the savior when you'e buying a 45 pound chuck!



For a little info on what it takes to cut threads, read this:

Awesome!! good for you. My best advice and I know you already know is BE CAREFUL!!!! These machines can and will eat you alive, even small machines like that. Take your time with learning. I can talk you ear off with a ton of info, more then you could imagine. If you ever want to chat just let me know. Do you have any experience with a lathe??? I recently sold my lathe and ofcourse I could have used it many time since I got rid of it damnit! But, I have access to a mill and a lathe at work again so it's all good.
 
Nice! There's nothing quite like mastering cutting threads...
They're getting few and far between out here but if you look around there are still some local city colleges that offer manual machine courses that could be a semester well spent.
 
Oh yeah, I forgot to tell you guys the best part...

























IT WAS FREE!!! :D:D:D:D:D

Thanks for all of the replies so far, I definately have some reading to do. :bow:
 
can't complain about free. Like it was said above, one of the biggest things is that the key to the chuck should NEVER EVER be left in the chuck, not even for a second. When you are done, take it out, its not even close to being a hassle. If you are in the middle of a project, sometimes that key can be in the chuck and blend in with something in the background, and bam...there is broken machinery, missing teeth, broken bones, etc.

Just take your time, do alot of reading on grinding different tips, feed rates, etc, and practice on alot of just aluminum or brass round stock since they are forgiving metals. I started working in a machine shop back in september and love every bit of it. I get to work on mills like that, as well as a big monarch that has an 18" swing. Not to mention I get to use some 3 axis milling machines. Its fun, just be careful!
