What would be the lathe equivalent of the Bridgeport? What I mean is
there must be a particular manufacturer and/or model of engine lathe that has gained reputation among those of you who have used them. Clausing, South Bend, something I can concentrate my search on. Thanks, Pat Landy |

Thanks, Pat Landy Hmm, I would have to say Southbend, but hey these are all good lathes and worth looking for as they all have a spindle that would allow 5C Collet Capacity. 5C Collets are the standard as developed by Hardinge as R8 is to the Bridgeport Mill 11" Rockwell/Delta 10" South Bend Heavy 10 11" Logan 12" Clausing I'm sure there are bunches of others.....just make sure they are complete, run them through all the gears, no cracks or breaks, look for wear on the ways (most of us can get by with clapped out lathe). I Dave at Meridian did a good right up on his site, "In praise of old Klunkers" http://mermac.com |

I'm not sure it really makes a whole lot of difference. Sufficient parts are available for many standard American lathes, including LeBlond, Clausing, Logan etc., that they can be maintained for many years to come. But, you really need to define what you will be making, in terms of size and materials, to decide which machine is best for you. Jon |

Clausing, South Bend, something I can concentrate my search on. Thanks, Pat Landy It's really a matter of opinion. My opinion of a South Bend is it's more of a gunsmith lathe. I had one once a 10" model "A" almost 30 years ago. Would I buy one now? No, I have out grown them, to under powered. Although they did make a nice gear head, which would have been nice. But I haven't seen many of them around. When I was looking for a lathe I wanted an 18" X 54 Lodge & Shipley. Don't remember the model right this moment. But the 20 hp and the heavy iron that went with it, made it a real nice choice in my mind. What I found first was a 16" Pratt & Whitney. 18.5" swing 7.5 hp and it fit in the space I had better. It has enough power to get the material out of the way real quick. I guess this isn't what you asked. I would think probably a 15" Clausing or LeBlond or a 14" Monarch would be the answer to your question. Still it's a matter of opinion. Also I think 15" swing lathe to go with a Bridgeport. Many years ago an outfit sold a Bridgeport type mill with a 15" swing lathe as a package deal. I thought that was a good combination and still do. Richard W. |

It has enough power to get the material out of the way real quick. I guess this isn't what you asked. Heh, I bet not. The old department shop had one of those P&W machines. I never had a chance to use it but I did get to see it in use. Possibly one of the most solid gear head lathes I've ever seen. I guess the question he posed was kind of unusual. It's tolerably rare to find a small home shop with a brigeport, but in industry they are indeed the standard milling machine. I suspect though that in a large shop that has a bunch of brigeports, it's pretty rare to see the same number of southbend lathes. In our shop the equivelent is the hardinge lathe. I guess that fits even better now that they are made by the same company. For real home shop use, there are a few names that stand out. Atlas, Logan, South Bend. Of course none of those folks still make new machines. But one will almost *never* see one of those brands in a working commercial shop.

Jim Have to disagree there. While Atlas and Logan may be uncommon in commercial shops, I've seen quite a few with South Bends. John Martin |

The only SB lathe I have ever seen at auction was a like-new heavy 10 ... in a maintenance shop. It was part of a lot bid for the entire maintenance shop. Had to take the lathe and 5 tons of oily junk together. This *is* the northwest, where there never were a lot of old shops with small machines. Bob |

I've had heavy 10's in production shops. But they are more typically found
in the toolroom making jigs & fixtures for the production shop. Tony "jim rozen" wrote in message ... In article , JMartin957 says... For real home shop use, there are a few names that stand out.

I have seen more SB's in production shops than any other brand of
lathes. You might define the shops as maintenance shops as they were not producing machine parts. One is a shop that produces aluminum boats. They were all older SB's, maybe 16 inch swing and six foot or longer bed. Dan jim rozen wrote in message Have to disagree there.

It's really really tough to make any money with old belt-drive SBs. Ummm, yes. The last shop I worked in, we have an 11 inch SB, and make quite a lot of expendable gaging plugs for a glass factory. With a Jacobs collet on it, it's ideal for this type of short run work. There have been times when we've tried to run it on one of the bigger lathes, and lost our asses in the process. Side note, for general information, I just bought the VIS .200 - 1.200 inside mike, pretty nice. Not as nice as the Starrett, but checks well with the master rings I have. Got their 5 - 6 and 4 - 5 outside mikes too, also nice. Haven't checked them with the blocks yet, but having the smaller four already, I'm not looking for any problems. More expensive than the chinese, but IMNSHO, well worth the money. |

Jim, I used to love it when I could take work away from a CNC shop, With my 1900 vintage Garvin #2 turret lathe. (Not hard to do with short run, (Less than 1000 pieces) orders.) Any more than that, and I didn't want it either. |

That's how my father-in-law paid for his South Bend, and later, after having mistakenly sold that, a Logan, now in my posession. He found someone who needed parts he could make, and made a few every day after work.

At best they're providing a well-needed service, but it's just break-even. If that.

Basically I've been figuring that the present market will not allow a small shop with a couple of manual machines to make money. Ed Huntress, and also teenut, expounded on the idea that if you try to start a business doing production of any magnitute with a small shop, running manual machines, you will probably loose your shirt. Or, as Ed put it, if you don't, you'll *wish* you had, because you'll be spending all your time turning cranks and handles. The "john henry syndrom" he called it. The notion that there is no way a manual machine and a man can ever outperform a CNC setup - for a machining run of any length at all. His rules for setting up a business were, IIRC Get plenty of capital. Get good shop space, with running water. Never mortage your home for financing. Have CNC capability Most important: have customers identified and waiting.

Is this an implicit statement about setup times? Ie, does the majority of the time for a short run get spent doing the setup, so if you are good at that, you can beat the actual total time, even if the run time per part is somewhat longer?

Far from it. Just that they're somewhat less common. The Atlas, though, is less often found in commercial shops because it is a less substantial lathe. Not throwing rocks at it - I own one. Should have made that clear. John Martin |

Second ops, is the roll of manual machines if you dont have hip slick and cool subspindle machines which will do both ends of the part at the same time. The DV-59 is such a lathe, and they are in every shop I deal with. Short runs, second ops, reworks, tool making still play a part in why you keep a manual lathe around. Its indeed true that many state of the art shops dont have a manual lathe or even a mill around. They also dont have a bench vise, hammer or flashlight. They are configured to run a series of parts as effeciently as possible with as little human interaction as possible. They seldom have a maintainence department, or maint guy, and contract out for such services. Its actually more effecient and cheaper. Until the hip slick and cool machine takes a **** in the middle of a hot order ("just in time", remember?) and you need to fix something NOW, or to open up a bore .002, or to face off the part another .005, etc etc. Or to make an adapter, or fixture or...etc Gunner "To be civilized is to restrain the ability to commit mayhem.
