Re: I just bought a Boulder Precision metal lathe ML 714 anybody have one?

If this is your first experience of?mini-lathes, you may not be familiar with "LMS", which refers to Little Machine Shop. Their user manual is at <??>. It refers to the Sieg version of the mini-lathe. Having found a pic of the "Boulder"?machine on the interweb, I think yours may be the Real Bull version. Seig and RB are the two main Chinese suppliers of mini-lathes, though they may be painted and badged to suit the requirements of different retailers. The differences between Seigs and RBs are minor, and?parts are interchangeable, so a manual for a Seig will be equally applicable to an RB. ? Andy ? To: 7x12minilathe@... From: mertbaker@...

Re: Best to use for cleaning red grease off lathe + oil for cutting fluid & way oil?
The dark thread cutting oil for plumbing contains sulfur, which helps prevent chip welding. If you find the odor objectionable, there's a clear version without the sulfur. Instead of buying a 10 lifetime supply of way oil, chainsaw bar lubricant comes in quart bottles with a dispenser spout.

The idea of using scraps of PVC pipe for practice is because it's cheap enough to learn with and unlikely to damage anything when the inevitable learning mistake occurs. Another reason to avoid cheap taps is their high probability of breaking in a project. Extracting a broken tap without damaging the object it broke inside of is difficult.

Re: Best to use for cleaning red grease off lathe + oil for cutting fluid & way oil?
It's usually handy to have several squeeze bottles around.
For example, even though the smaller can size for cutting fluid is easy to handle, it is even easier to handle a small plast bottle of it. Here is a common type: Here is one with a fine tip applicator from Enco: "Plastic wash bottles" have angled spouts. These are handy to hold alcohol or acetone, some solvent, or even just water used to put on something for cleaning. There are all sorts available. Here are some: Another handy fluid delivery gimmick is the "push down" dispenser or "pump" dispenser. It's really handy because you don't have to pick it up to get a little fluid on a rag. Here is one with a metal top like I have always used... Here is another type: As you can see, these come from many sources such as machinery supply houses, chemical supply houses, and art supply stores. Plenty are on ebay and Amazon, too. One thing about such containers... Many people get lazy and don't label them. Anything like this should be clearly labeled regarding what is in it.

Well for the lathe I will use one of my little blue pump bottles with a flexible nozzle on the end, I just meant for other uses of WD-40 where you need to be able to spray it.

Instead of using their pressured sprayers, just put it in a squeeze wash bottle.? It will minimize any over-spray and waste. -rw From: nissan.370z To: 7x12minilathe@...

¿ªÔÆÌåÓýCharles, I see you use a lot of WD-40.? Just so you'll know, here is what it consists of:50% Stoddard solvent (i.e., mineral spirits, similar to kerosene) 25% liquified petroleum gas, or carbon dioxide (as a propellant) 15% Mineral oil (light lubricating oil) 10% inert ingredients So, you could mix 3 parts of Mineral spirits (from the paint store) and 1 part light lubricating oil, and use it where you would use WD-40 and at a lot lower cost. |

Re: Best to use for cleaning red grease off lathe + oil for cutting fluid & way oil?

Thanks everyone. I didn't think about WD-40 or Kerosene for cleaning the grease off. I have plenty WD-40 but no kerosene right now (I wouldn't use gas to clean it off though).
I surely wasn't aware I could use WD-40 as cutting oil for Aluminum. That is cool! I'll buy one of the cheap cutting fluids mentioned for cutting steel too. As far as synthetic motor oils go for lathe way oil, does it matter what weight I use? I have a left over quart of 5w30 Synthetic Oil that isn't being used. As far as plastic pipe to practice on, I have been looking for some dlerin or similar to use. There is a new eBay seller that combines shipping very well and he just got delrin in (is that good to practice on?). He specializes in small orders. I ordered several 12" long pieces of 6061 round Aluminum stock from him (3/8", 1/2", 5/8", 3/4", 7/8", 1" and 1-1/8" diameters) and he shipped them all for the single item shipping price Flat Rate Priority Mail from CA for only $4.95 (the stock was cheap too), (the next shipping price for larger orders is around $10.95 I think for next size package). Some places dont combine shipping like that on small orders. Hope I am allowed to mention eBay sellers on here, here is his link if anyone needs to order some small pieces of stock. Just ask for what his combined cost will be for your order so you know what he can fit in what size package. I'm open to any other places anyone knows about too though. Later on I will stock long lengths like I do steel plate, box tubing etc. Thanks again everyone for the advice! Charles |

I use mostly TapMagic for all cutting, except for aluminum. WD-40 is best for that. Enco's propietary cutting fluid is OK, too, and I like it for tapping brass, as TapMagic causes the swarf to turn green. Yuck!

TapMagic and Enco's fluid come in 1 pint cans, and I transfer it to these 1-Oz. bottles: These things are next to my LeBlond and the Mini-Lathe, also the B'Port. As you said, a little will last seemingly "forever", so cost isn't a big deal. And, to the O.P.: Look at the various web sites for hints & tips for adjusting and setting up your new lathe. There are a number of modifications that are nearly mandatory, IMO, such as the cover over the apron gears. Adjusting the carriage and lead screw are also mandatory. <<Jim>> ----- Original Message -----

Parts of your machine are plastic including the wiring. 3.

I see you already have some opinions, so one more won't kill you.
Kerosene is good for the initial cleanup. Somebody mentioned some use gas which, for obvious reasons, should NEVER be used for such cleaning. You mentioned "affordable" regarding cutting oils. I don't know any that aren't. But since proper usage will prevent breaking expensive taps and ruining expensive parts, even something expensive (if there is such a thing) is cheap. Tap Magic ProTap can serve all your tapping needs on all metals pretty well. You can also use it as a cutting fluid. For the typical hobbyist, a small container will last a very, very long time. Here a link to Enco for a 4 oz. can for $2.86. It's easy to have a couple of these laying around handy. This (and other Tap Magic offerings) is a very mainstream product and sits on a lot of machinists work tables. I used to use a sulpherized dark cutting oil for steels, stainless, and iron, but got tired of the stinky smell. But some people still like to use that. Tap Magic has a reasonably pleasant smell, at least to me. Water soluble cutting oil was mentioned but I wouldn't recommend it unless you really had a need for it. Such as flood cooling on the mill or lathe. If you aren't using flood cooling, I don't think it brings anything to the party except the risk of bacteria growth which can also get pretty stinky. You can actually use almost anything for a way lube on these little machines and the idea of using a synthetic motor oil if fine. An opinion about tap and bit quality: I think it as important to use high quality taps and cutting bits as it is to use high quality tapping and cutting fluids. Cheaps taps, especially, are throwing away good money since they tend to be shortlived and give poorer results. Chuck K. <SNIP> |

Cleaning fluids:? WD-40 or kerosene Cutting fluids:? WD-40 for aluminum, Heavy pipe cutting oil for steel Way oil:? Mobil 1 Vectra #2 Way oil. You might want to look in your local area for the Vectra, if you do want to order on-line.?
