SB Heavy 10 Vs. Clausing 5914 Lathe
Hi Guys,
I have the option of purchasing a South Bend Heavy 10 with D1-4 Chuck or a Clausing 5914 lathe. Both are tooled about the same and price is about equal ($2,600). Which is more rigid and would be considered a better lathe? I am a hobbyist but want to purchase a commercial quality lathe. Would I be better off passing on both and looking for a larger more rigid model? Thanks afor the help. Joe |

Joe That SB better be super tight and minty fresh at that price, or include a taper attachment, steady rest and Aloris toolpost plus a bunch of nice goodies. |

Which is more rigid and would be considered a better lathe? I am a hobbyist but want to purchase a commercial quality lathe. Would I be better off passing on both and looking for a larger more rigid model? Personally, I would go for the 5914 (assuming that the variable-speed mechanism -- if fitted -- is in good shape.) The 5914 should be (like my 5418) a 12" swing lathe, with adequate diameter though the spindle so it can directly use 5C collets with either a handwheel drawbar or a lever-style drawbar (which is what I have). I *think* that the "Heavy 10" will also handle the same collet setups. How about defining "tooled about the same"? 3-jaw chuck -- ideally with two-piece jaws so you can use soft jaws when appropriate. a 6" or 6-1/4" diameter chuck is about right for a 12" machine. Perhaps a 5" for the 10" South Bend. 4-jaw independent chuck -- for a 12" machine, a 10" chuck is the maximum size. For the 10" machine, probably an 8" chuck. faceplate -- for bolting awkward workpieces to when a chuck just won't work. dog driver -- looks like a smaller faceplate, but instead of having slots (which don't extend to the OD) for bolting down workpieces, these will have one fat slot which extends to the OD, and another fat slot which covers smaller diameters. collet closer -- Ideally a lever style, but a handwheel style still beats none. 5C collets are vastly preferred, because they are made and used in such quantities so you can get them relatively inexpensively -- especially if you expect to damage the collet with the work and don't want to put your nice ones to that kind of use. taper attachment -- A very nice attachment to have for the lathe. It makes it easier to make your own adaptor sleeves and other such things. steady rest -- For working on the outboard end of something which can't be mounted between centers, yet is too long to properly support only at one end. follower rest -- Necessary for turning long thin workpieces to size and for threading them full length -- especially nice for making a replacement acme leadscrew for your lathe or something else. QC toolpost -- Ideally an Aloris BXA for the 12" machine. For the 10" SB, perhaps only an AXA, depending on what will fit properly. A BXA will handle 5/8" shank tooling, while the AXA only 1/2" -- so the BXA is more rigid. The more toolholders which come with this the better. Ignore the standard knurling holder, with a pair of knurls at one end, and a slot for a facing or boring tool on the other end. In particular, I like the BXA-16N holder, which is designed to take two triangular inserts (the 'N' is for negative rake, which can include inserts which provide a positive rake by a properly dimensioned chipbreaker groove). This is probably my most often used holder, kept set up with good general purpose inserts. One insert is used for turning, and the other for facing, and the height adjustment covers both at once -- you set it properly for one and the other will be right as well. Live center -- (ball bearing center) in the proper taper for your tailstock. Dead center -- for the headstock spindle taper (or an adaptor sleeve). Once upon a time, this was called the "live" center, because it was powered by the spindle, and rotated, while the tailstock one did not. Adaptor sleeve -- To fit your spindle's taper to a convenient taper for both a center and for driving tooling. Bed Turret -- Not likely, but possible. This will handle (typically) six tools, (manually) feeding each to a preset depth, and then advancing to the next tool when the turret ram is fully withdrawn. My Clausing came with one with a matching serial number to that on the lathe. But -- I had to chase down a normal tailstock to fit the machine. ******* Now for a couple of unusual chucks ******* 6-jaw chuck -- Nice when working on relatively thin-walled tubing, as the extra jaws significantly reduce the distortion caused by the chucking. Two-piece jaws would be nice here, or at least make sure that you also have the outside set of jaws with it. Mine does not have either, so I am somewhat limited by what I can do with that chuck. 4-jaw *universal* -- unlike the 4-jaw independent mentioned above, this one has all four jaws moved at the same time by a key just as in the usual 3-jaw chuck. It is particularly nice for lots of work on square stock (as it will be close to well enough centered for most work, just as a 3-jaw). It is also better for thin-walled workpieces than a 3-jaw, but not as good as a 6-jaw. ******* General chuck information ******* For *any* of the universal chucks (3-jaw, special 4-jaw, and 6-jaw, an "adjust-tru" style is a noticeable benefit, as it allows you to tune the chuck to being more true to the center of the spindle than is normally the case with a universal chuck. The 4-jaw independent can get anything set true with a bit of work, but you have to repeat the work for each workpiece. With the "adjust-tru" or "set-true" (or whatever the manufacturer chooses to call it), once you set it for a given diameter workpiece, it will be quite close for repeats of that diameter -- unless the scroll and jaws are badly worn. Soft jaws can be bored to fit a given workpiece diameter, and are easier to true than the "adjust-tru" style, and are particularly nice when you need a depth stop as part of the workholding, so all the pieces match the length. There is a limit to how many times you can bore the soft jaws for through fed workpieces, so each system has its place. I'm sure that there must be something which I have forgotten. But this is what I can think of to watch for on your candidate lathes. The more of these you find, the better -- assuming that the machine is in good condition.

Don,
Many thanks for the response. After reading your post I did a little more checking. The SB comes with far more of the tools you mentioned than the Clasusing. Both lathes are in great condition but it is now apparent that the SB is better tooled. Having said that, is the Clasing a more rigid lathe that would make you lean towards it even with less tooling? Thanks again. Joe... "DoN. Nichols" wrote in message ... In article , JB wrote: Hi Guys, I have the option of purchasing a South Bend Heavy 10 with D1-4 Chuck or a Clausing 5914 lathe.

Prices for spare parts from Clausing Service Center have in the past been more affordable than equivalent parts for the SB (based on postings here over the years). However, the prices on some parts have doubled in the past six or so years. This does show that they are continuing to *make* parts for them, not just to sell off old stock, so you can expect this sort of thing to happen as manufacturing costs go up. You probably should get opinions from others as well -- since I am obviously biased. Thanks again.

If you have the space and getting the machine to its "home" is not a problem
I would go with a heavier machine. The Clausing is nice but from what I have seen parts are getting very pricing and the drive setup can be a re bitch. The SB for that price is over priced unless it has hard ways is near perfect and has ALL the goodies. Lathes that are one step up often cost less, up here in the north east $2600 will buy a very nice lathe. I picked up a very nice SB 14" fully tooled for under $1000. I have it and a heavy 10, I haven't used my heavy 10 more than 2 times since I bought the 14", the amazing thing is the heavy 10 has better resale. if you go to www.motherearthrecycling.net and click on "shop" you can see both. I will be selling the heavy 10 in a month or so. (when prices rebound some). Last week was the time to buy, prices will go up some for the winter. "DoN. Nichols" wrote in message ...

Its threaded, the 14" is a d1-4, if the heavy 10 was a d mount I might keep
it. The heavy 10 has a very nice buck adjust set 6 jaw chuck. "Artemia Salina" wrote in message ... On Sun, 28 Aug 2005 20:46:01 -0400, Waynemak wrote: I will be selling the heavy 10 in a month or so. Wayne, What type of spindle nose does that Heavy 10 have? Threaded? Cam-lock? Thanks. |

Joe I would pay less attention to the tooling than to the lathe itself, and go with the best lathe. That would probably be the Clausing if it's in good shape. The tooling would then only come into consideration in deciding if the price was OK for the lot. A lathe you're not happy with is no bargain even if it came with lots of tooling. You can incrementally add/upgrade tooling later once you have a lathe that you're happy with. No comment on the prices since I haven't seen the machines and haven't shopped for a long time. |
