Metal Lathe ???????

[russ498]

I am getting ready to order n 8X16 metal lathe. Budget dictates that it be an Asian machine. None of the ads indicate what sized cutter bits to buy. I see 1/4", 3/8" and 5/16". Is there a way to adjust the height of the cutter so that it meets the centerline. It looks like they index on the bottom of the bit, so they would each meet the work at a different height.

Second, I am looking at Amazon as the primary source for all of the add ons and accessories. Is there another source. I prefer to give my business to small shops, even if it costs a little more, within reason.

Last, how about suggestions on machines. I can't spend more than $1500. I know most of them are made in the same Chinese factory, but I'm told that retailers make substantial changes both good and bad. They all look similar, but.....

That size lathe will likely take 1/4" cutting bits but don't quote me on that. It's all about the top of the cutter being just barely below the center line of the headstock. Each lathe maker might have used different components or the headstock to bed height is different. You'll need to measure, or eyeball if you're good enough, to know. If the cutting bit is way below center (1/32" or more) then you'll need to shim the bit up an appropriate amount. Use the largest cutting bit you can without going above center. Using shims is a PITA (to me) and that's why many others swap out the index type holder for a dovetail quick change type that has a set screw for setting tool height. It would do you well to find out exactly how large a cutting bit you can use before ordering bits you can't use. Would also suggest getting HSS instead of carbide, you probably won't be able to sharpen carbide but HSS you can.

Read all you can about lathe operation and SAFETY, the lathe is a dangerous machine to operate. Rather than shopping at Amazon I'd suggest locating an industrial supply house, you may have one near you. Amazon carries a lot of **** that's not worth the purchase, industrial supply houses that cater to machine shops can't afford to lose customers with crappy products.

I've been in machine shops for 35-40 years and would strongly urge you to read about SAFETY. Would less stridently suggest you read, watch videos about operations, and ask for advice before making purchases. The path you're embarking on can be costly or money well spent. Ask questions, be safe.

LittleMachineShop.com is supposed to be one of the better sources for mini/micro lathe parts and tooling. You will probably want to upgrade from a lantern tool post to a QCTP almost immediately, if the lathe you order doesn't have it as an option.
Books: "How to run a lathe", 15th edition, from South Bend is one you definitely need, as well as How to run a lathe, Care and operation of a screw cutting lathe, by O'brien, should be the first two you get. Both are available on Amazon via Kindle, or paper forms. If you have Kindle Unlimited, both are downloadable to your reader.

Are you building watches or other tiny parts? I've been keeping my eye out for a lathe, but something around 16x60

+1 on Little Machine Shop (LMS). I'd even consider buying your machine there. They have great customer service as well.

I would not recommend Amazon, as they do not police for fakes and inferior merchandise. There was an article awhile ago about some guy who sold metal-jacketed computer cables and he was getting all these complaints. He ordered one of his from Amazon and when it came he determined that it was a knock-off. Amazon didn't help him out at all. According to the article, they just put all the metal jacketed computer cables in one big bin and grab one when there is an order.

If you buy from a place like LMS you're assured it is a quality product, and you are supporting a small business as well.

This lathe might suit your needs: SIEG C3 7x14 Mini Lathe It's currently on sale for $800. That leaves room for tooling. You might spend that much on tooling, but you can spread it out as you need it.

This one is also a good choice, though pricier at $1,350: HiTorque 7x16 Mini Lathe

LMS has accessory packages for about $400, so you can get enough to get you started.

It is my understanding that Sieg makes the lathes for everyone else. There are lots of YouTube videos and other resources for "fixing" the cheaper lathes that can be bought at Harbor Freight and other discount retailers.

You might want to check out and join hobby-machinist.com. It is a friendly group of hobbyists who can answer your questions and help out with any issues.

Good luck in your search!

I am making pens primarily, but do want to expand into bigger projects. Little Machine look great but are twice my budget.

I went through this several years ago, I ended up a USA made Sherline lathe for the little stuff.

Over your budget but...
I bought a Precision Matthews PM 22 and have made hundreds of parts for my motorcycles, I am extremely happy with it.
