where do you find a good lathe for smith work

[kraigwy]

I have a Jet 12 X 36, with 1 1/2 in spendle bore, that I got in the early 80s that is still going good today. I'm put together a lot of Target Quality Rifles on it. I also have a Jet 16" Mill/Drill that I got about the same time that I use dern near as much as the lathe. Even fluted Barrels on it.

I also have a smaller Jet 6X18 lathe for smaller parts.

All these are over 25 years old, I don't know the quality of Jet Equipment now.

Set up and messuring are just as, if not more, important as the quality of the equipment.

If you take machining classes, a lot of time the school will let you use their equipment. I started learning machining years ago, and fell in love with it. You will develop your skills in relationship to how dedicated you are. I took an accelerated program that taught manual machining, and cnc. I helped keep the shop clean and maintain the equipment for my teacher, and he ended up giving me keys to the shop. If you want a good lathe, get a Hardinge. I have never seen one make bad parts, in spite of how old they were or how badly they were treated.

Nice shop longrifles! Six years later, I still regret selling off my shop. Meanwhile, I'll try and talk Mrs. Grymster into one of these. It would make a very nice gun-building tool. My employer owns one and it's a hell of a machine.

I HATE the 3 in one tools. Especially the ones that swing large workpieces. They by necessity have to have a lot of height between the table and the workpiece, so there's flex and chatter. Plus the crossfeed is minimal, drastically limiting their usefulness, and they usually do not take common R8 tooling, so you have to spend 3-10 times as much for collets, etc. due to the morse taper.

I'd call enco. I have gotten a couple machine tools from them, and they are; prompt, competitive, and have most the things you will need. Their website kind of sucks, but they will send you a free catalog. Here's a couple machine tool distributors;

I've heard good things about Grizzly, but have no personal experience. Mill wise, I recently purchased a SQUARE column bench mill which is REALLY cool. Large table and feed lengths, takes R8 tooling, features are very well thought out, and the gearbox makes speed changes very easy. Square column allows downfeed on the vertical bed with the spindle locked for more flexibility. These things haven't been around for long, but you get the capacity of a floor model with the weight and cost of a bench model.

Lathewise, I'd mainly be looking at through feed capacity. Some feed 25mm, which is .4 mm shy of feeding 1" stock. Things like that are worth considering. A gap bed lathe will allow significantly large pieces to be turned without increasing toolpost to bed height.

Happy hunting!

what tooling would yall start with. and here's a million dollar question, quality measuring equipment at a reasonable price. when I get the leathe $2000 will be about my starting max

[Swampghost]

I've never skimped on measuring equipment, they are the most critical part of the process.

I use Brown & Sharpe, Starrett and Mitutoyo in that order.

[grymster2007]

what tooling would yall start with.

Measuring instruments from any of the manufacturers that Swampghost mentioned will be fine and those three brands comprise the majority of my tools, but you could find cheaper tools that are adequate for gunsmithing. I would have both a travel and test indicator. You can get them in .0001" resolution, but .001" for a travel indicator and .0005" for a test indicator will probably suffice and be a bit cheaper and/or provide more range for your money. Magnetic base indicator stand is a must. I like 2" range travel indicators and having a magnetic back-plate for one helps too. Outside micrometers in 0 - 3" should be sufficient and some 8" digital calipers. Tubular style inside micrometers are nice and accurate, but usually have a range starting with a minimum 1.5". Telescope gages will get you down to .313". They make inside micrometer calipers that are fairly accurate, but limit the depth you can reach. I'd probably buy pin and plug gages to get the range <.313".

Nice to have measuring equipment:
Granite surface plate
Surface gage
Sine bar
Angle plates
Parallels
1-2-3 blocks
Joe blocks
Thread wires

Once you have your lathe you can select
Tooling:
3 or 6 jaw chuck
4 jaw chuck
Collet closer and collets
Square and hex collet collet blocks
Faceplate
Lathe dogs, for shaft work
Tailstock chuck - having several is nice
Clamps - Kant Twist and hold-down
Turning, threading and boring tools - you might consider ceramic insert tooling. It can add a lot of versatility, but to make sure you get the right stuff, don't buy until you settle on a lathe.

There's more..... lots more, but I grow weary.....

This is a surplus dealer that is pretty honest with condition and hours. http://www.sterlingmachinery.com/ I look for a heavy rigid machine, with enough size to do barrels. I travel 9 months out of the year and visit every gunsmith I can (80 to 100 a year) Cnc machines are for production work and I have seen very few in professional gunsmith shops actually none being used for just smithing. Most shops can't justify the expense or time it takes to set one up or program one for a single part. If you were going to built a run of parts you may be able to justify it but for the most part a manual machine will work for the gunsmith.

[grymster2007]

Cnc machines are for production work

I agree that general gunsmithing doesn't require CNC machines, but they are not used solely for production. We use CNC to produce the vast majority of our work, which is non-production work; mostly one-off items, with the occasional lot of two to ten. And many times, I've disproved that CNC is slower for all but the simplest of tasks.

I bought a good second hand lathe, and separate mill/drill with heaps of cutters and tools for each off a guy that was moving for the 3rd time in 2 years, and didnt want to set up his machines (again) at the new place. I picked up the lot for $Au2k

I also build parts for Gyrocopters and Ultralight (microlite) aircraft, so my lathe and mill cop a flogging

I have made many parts for guns and of course the cannons and other norty things.....

I would suggest looking for second hand, either private or auctions. I dont think 3 phase is neccessary, however our standard voltage is 240v 50mhz here, you guys have 110v there, so 3 phase might be the go, like the others have said. I don't care what drives the lathe, just make sure the headstock and everything that is turned is well built, solid and straight. Mine is 38mm thru the headstock, bigger is better Make sure you get something you can use good quality tools in, that the size tools are cheaply and readily available. My lathe is set up for 16mm tools, so when I need a tool, I know if it is a 16 mm tool, it will fit my lathe perfectly.

Just remember, when you do get a lathe, you will get addicted to making all sorts of things and find you had friends you didnt know you had

[smoakingun]

as for lathes, I bought a 14in grizzly about 2 years ago(the only thing it didn't come with was the aloris tool post) the machine will turn 0.0005" as long as my indicators are in cal. (digital displays are a god send) as for a mill, I picked up 1950 vintage index in about 1992, (I rebuilt it) and added digital indicators to it about 3 years ago it will still machine to a half

I highly recommend calling those numbers and requesting your free catalogs before buying ANYTHING. Even if you don't buy from them, you can look at what's available, and peruse the tooling.

As to tooling for a lathe, I really like having a wedge (not piston, but they work well, too) type toolpost for switching RAPIDLY from one cutting tool to the next. You can set the toolholders to be at the right height, so you can switch from one to the next simply by pulling a lever and slipping another on.

Another thing that is really nice is indexable carbide tool holders. You can get a set pretty cheap, and the inserts can be rotated if you ding one up. Plus they will all take the same insert, so you can have spares.

A live center (bearings) to hold your workpiece is really nice to have, and dead (solid) centers can be handy, too.

One last thing to consider for basic tooling, is a boring bar for doing inside work on a workpiece.

My inclination is to say get some cheapo measuring tools and learn to use them well. If you even need to ask where to get tooling, you probably will not be served well by buying really pricey measuring tools. (JUST MY OPINION please spare me the wrath! ) You may not be able to hold better than .001" with cheapo's, but if you aren't used to using them, you probably wouldn't be able to hold those kind of tolerances even with higher quality ones.

My reasoning is that you will be better served HAVING all the measuring tools within your budget. A Dial caliper is a VERY handy tool to have. Not terribly accurate, but quick. Telescopic gauges and micrometers will cover most things requiring more accuracy.

The advice I am giving is based on the assumption that this will be somewhat a learning experience, and a hobby sort of thing. You can always spend more money, but for the hobby machinist, I think often having less than the best, but being able to budget in more tooling may make more sense.

Oh, and one last thing; BEWARE of Harbor Freight junk! I recommend you don't get your measuring equipment there.

PS With Enco, a lot of their stuff goes on sale, and the sale prices (including lathes/mills etc) are often substantially cheaper. If you can get a sale flier you might save a few hundred bones on the lathe alone.

Look in pawn shops,watch Craigs List,etc.Folks are hungry,and selling things off.

For mics,I'd get quality in a 1 in mic.Carbide faces,friction thimble,tenth vernier.B=S,Starret,Mitutoyo. Mine's a Lufkin,but thats old.

A good 6 in dial cal.I like Brown and Sharpe or Tesa.

A depth mic is useful chambering.I prefer the small base Starret blade type.The blade spindle does not rotate,and can be twisted to any orientation.

The 3 in set is probably enough.

A 5x jewelers loupe is very useful .

a good(starret or B+S satin chrome flexible 6 in scale is a must,get the .100 graduations along with fractions.

Later,space blocks are about $30 and gage pin sets are real cheap,for what you get.

Carbide insert tools for V threads and a small grooving tool holder will set you up for the sq threads in Springfields,Enfields ,Rolling Blocks,etc.

A nice thing about insert threading tooling,you do not lose your lead if a tool nose fails.
