What is a lath good for
I found a 36 inch used metal lathe for sale for 350. What would this be
good for? I like working with metal. I have a couple of welders and am wanting to increase my tools in my garage! |

Some people make fittings, steam engines, brass cannons, telescope/camera adapters... Camera adapter plates for medium and large format cameras. I think my machines have been used more for that in the last year, than for anything else. Having a friend who is a semi-pro photographer, and who knows lots of people, probably has something to do with that. It's fiddly, one-off, very occasional work, which is the sort of thing I like. Want one or two? No problem. Want a couple dozen? I know a guy with a shop, here's his card... |

Make SQUARE things too. It oftens comes as a real shock to
non-metalworkers that you can TURN a perfect CUBE on a lathe -- as long as you've got a four-jaw on it. - Carl "Dave" wrote in message ps.com... wrote: I found a 36 inch used metal lathe for sale for 350.

Now that is something I would not think of, since what you are really
saying is that you can make flat surfaces. If you are making a flat surface how do you decide whether to use the lathe or the mill? Carl Hoffmeyer wrote: Make SQUARE things too.

"Dave" wrote in message oups.com... Now that is something I would not think of, since what you are really saying is that you can make flat surfaces. If you are making a flat surface how do you decide whether to use the lathe or the mill? Almost anything that can be done on a mill can be done on a lathe .. and vice-versa. The choice is one of matching geometries. For example, while one can turn things on a mill, you would be hard put to turn a 1/2" diameter by 24" long shaft on a mill. But a 1/2" thick by 24" diameter might be do-able. Similarly, a rotary table is a slow and inconvenient way to turn things .. but suppose you have to turn only a partial circle. You can, as stated earlier, make flat surfaces on a lathe using a four-jaw chuck or some other holding device but it will get increasingly more difficult as you progress and take far longer than the same operation on a mill. Also, to mill a long item on a lathe would be difficult and tedious using a milling attachment, or require a huge lathe. But the decision isn't difficult. If it's mostly flat, you go for a mill. Mostly round, its the lathe. Also, try threading on a mill without using taps or dies. With very really modest amount of experience, and if you have both tools at your disposal, it is rarely a deep question. The interesting question, though is how to machine things that are difficult on either a lathe or a mill ... a keyway slot in a pulley is the first one that comes to mind --easier on a lathe than on a mill. Also, the question of milling on a lathe should be restricted to not using a milling vice because that's really a kind of cheating. Conversely, except for doing partial circles, a rotary table should be left out because it is to the mill what the milling vice is to the lathe.

Can you "mill out" with a lathe? Like make a rectangle hole bigger in a
pto yoke? |

With the right tool attachments and a little ingenuity, there is little you
CAN'T do on a lathe. As for your specific question a little more detail is required. If you want to mill a rectangular hole with rounded corners, then yes, with the proper tooling attachment sit might be done on a lathe (it might be better done on a mill). If you want a retangular hole with square corners, then I can't think of any rotating machine that will do the job. You will need a broach or punch. For shaping metal the three fundamental machines seem to be the lathe, the mill, and the bandsaw. wrote in message ups.com... Can you "mill out" with a lathe?

Holding a concrete pad down!
Seriously tho, check the lathe out for wear and operability. If it is even a moderately well worn lathe, it will be a valuable item for your home shop. If you're in the Southern Calif. area, I'd love to come over and do some work on lens cells for my telescopes as well as eventually doing some mounts for those telescopes. A 36" swing lathe can handle the large parts that need to be swung without any problems. I'd also put a 1 HP. 115V motor on the lathe so that you can use it without needing 3ph. power although that will mean that you can't take the big cuts that the original motor would be able to do. -- Why isn't there an Ozone Hole at the NORTH Pole? |

What happened to your toe, the cats chew on it? g Jim Sigh...it still hurts to think about it. When they say you cannot remember pain..take it with a grain of salt. My son and I were moving my hydraulic press. It was dark in that area at night, we were in a hurry, and he missed removing one of the 1" thick, 6x8" press plates which was sitting on the press. It slipped off. Nailed me on the diagonal across the end of the foot. Busted 3 of the 5 toes. Fortunately, it didn't land on the right foot, else it would have busted 3 of the 6 toes.

I guess it could have been worse, if it had landed on the instep it could have done much worse damage. Ever considered steel-toed flip-flops? Just out of curiosity, what's kind of tooling does that smaller Gorton mill take in the spindle - B&S or MT?

Stryped sez:
"What is a lath good for?" A lath is a thin narrow strip of wood useful for building lattices or holding plaster to walls. Bob Swinney wrote in message oups.com...

Well if you have a bunch more lath's you can naial em on the studs and
plaster over them like they used to do in old days before sheetrock and gypsum board was invented.......Or you can nail em on your roof rafters and then install slate or cedar shingles on them...... ============================================== Put some color in your cheeks...garden naked! |
