    Hey Guys,

    Can anyone recommend the type of oil or wax (or otherwise) needed to tap into aluminum?

    I'll be tapping new threads into the engine block to accommodate a brand new heartier hose water union for my 79 308 GTB.

    Thanks Guys,

    Chris.

    Believe it or not about the best thing out there is WD-40. There is a product call alumtap that is one of the few things I've found that work better, but you won't have a problem with the wd-40

    Granger is a pretty good generic source for cutting/tapping fluids and sprays. No good machine supply houses around DC anymore. Can't even start up the lathe without hitting a lawyer with the chips but can't go out and buy a ball end mill without driving to Baltimore.

    I was put onto WD-40 as a cutting/tapping fluid by the Mini-Lathe & Mini-Mill guys awhile ago. It really does a great job. Most regular cutting/tapping fluids don't do that well with Al.

    tapmagic (aluminum version) is what I use when drilling and/or tapping aluminum in the machine shop at work. A very thin fluid that allows taps to go through aluminum as if it was soft butter.

    I've used the alumtap as a cutting fluid and it works very well, but I've never tried the tapmagic

    I buy all my machine shop supplies right on line. Check out Grizzly, MSC, and littlemachineshop.. Heck, lots of good stuff on eBay as well. Not only do I get my stuff on line, but it is WAY cheaper than the local supply house.

    Just my $.02

    I try to by online as well since no one local. www.useenco.com as well for the chinese stuff. Get on the mailing list for hot deals. Haven't heard of Littlemachineshop? I'll have to look that one up. If you are in the mid atlantic you have to go to the Cabin Fever Expo. Look it up online. Sponsored by Home Shop Machinist Mag. Fantastic show. Should be coming up this month. Amazing things people have built plus workshops and vendors.

    I have both a Chinese minimill (which I converted to R8 and CNC), and also a minilathe. They are both inexpensive and wildly popular, and can be bought from a variety of sources. My minmill is from Grizzly and my minilathe is from Micromark (they are another good source also). Under $600 each for the machines, and well worth it for me. I can make pretty much what I need for my cars right at home. (how many times do you need a custom bushing or bracket, or have to tap a PERFECT hole?).

    Naturally, they aren't the best machines in the world, but for the price, they're first rate, and "support" for parts is pretty impressive.

    Littlemachineshop stocks ALL, and I mean ALL of the spares for these machines, as well as a large variety of tooling for them. Chris over there is extremely helpful. Nice company. Good prices.

    I'm familiar with Cabin Fever. Those guys make some pretty impressive things. WAY out of my league.

    A lot of magic stuff out there, but believe me or not. The best lubrication for tapping or drilling into aluminium is methylated alcohol.

    Best regards from Germany

    I haven't tried it before, but my friend recommends me to try the tap magic, and these days I searched some online, found this one

    I bought this Square Column mill/drill from MSC a few years ago. Enco and MSC are the same company but Enco is much cheaper. I bought this from MSC becuase I wanted the Rong Fu(tiawan ) instead of the clone made in China. I was too cheap to pay for the third axis on the DRO so I made my own out of a cheap digital caliper.

    Nice rig, and nice size. My mill is a bit limited in X and Y travel due to it's size. This has messed me up on a few non-auto projects (but for my car stuff, it's adequate). For example, I have CNC plans that I drew for a mechanical grandfather clock that I designed, but my machine is too small to cut some of the biggest gears. Bummer.

    I like CNC though. VERY fun to play with, since I converted. The conversion also solved the VERY weak Z axis problem that is common with minimills of my type. I do some custom engraving for a friend who builds custom electric guitars on my machine on occasion, among other assorted projects. My friend is an autocad ACE, and I have the right programs to clean up his drawings, and convert to G code. VERY fun. Some of the best money I think I've spent.

    I'll try to take a few snaps of my rig this weekend.
