I have a set of those Kobalt taps, and a set of Hanson taps from Home Depot. The Hanson taps are much better quality IMHO. They seem to be sharper and harder. They cut more easily. Also, some of the

In case anybody's been wondering, I've been offline since I packed my computer away on March 22nd to move. Now it's set up again, but my in-box has 1600-odd messages, so if anyone sent me an e-mail

I wrote a long instructional on this some years ago, which is posted on the mini-lathe site at http://www.mini-lathe.com/Lapping/mt_lap.htm If I were doing it again, I'd use a coarser abrasive, such

Thanks for the pointer, checked that earlier and the pix was missing, but I get the idea, I think that is the purpose that the drill chuck is serving for here. Once I get some bigger aluminum rod, I

:-) Nice feeling! Being able to re-do something complex does indeed have a lot of benefits :)! These are just for adjusting screws and don't need much power, it would be pretty easy to crush that

LOL, already doing that :-/. Got tight for time while I was out today and decided to just use my little PCB drills to get it out since I have to bore it out more anyway. I'll keep them, but I sure

Exactly what happened here. I picked up a couple more of those today: http://www.lowes.com/lowes/lkn?action=productDetail&productId=232566-1083-358001 Not sure, but I suspect these are not really all

Hi Ian, Is this your beastie at www.realbull-machine.com/images/CJ0618.jpg <http://www.realbull-machine.com/images/CJ0618.jpg> ? I assume those plastic guards are a later addition. They do look more

Hi again, I just had a reply from Doug who sells EDM books via that (broken) link below. He's still in business but his ISP has had his site down for a few days and he's spitting chips over it. So if

Hi, I stayed clear of using acide on a steel job but I guess if you use it strong enough that the job doesn't take days then you can keep an eye on progress and stop it before it destroys everything.

Hi Mark, Nice concept but I'm pretty sure my tap was too brittle hard for that. When it initially broke it left a stump protruding. It crumbled like glass when I tried to grip it. It actually broke on

Hi Rob: I am also a newbie. I bought a 7x12 Cummins in summer of last year. Doug Briney: The Home Machinists's Handbook, McGraw-Hill, available at Amazon.com, very basic and geared towards the

I have one of these tool holders and I doubt that the rocker section is a Woodruff key. It's about 40mm long and 12mm wide. I don't think Woodruffs are that thick. It's also fairly shallow from the

FWIW, my usual remedy for broken taps in something I have too much tim into to just remake: I haven't had luck using alum, try nitric acid (it can be diluted, no need to play around with concentrated

Hi Vikki, Glad you didn't spontaneously freak out. That's a sign of maturity and starting to get comfortable with your skills and ability to sort things out. I think you can get alum from a

If you haven't found alum, try a swimming pool/spa place; it's used to lower pH. It's also used in gardening to lower soil pH. The "trick" works because steel is acid soluble, aluminum is pretty much

LOL, I sure did. Watching that one tap corkscrew when trying to start it was kind of amazing. Slowly I learn :). Threading on the lathe, once so intimidating, I don't think much about anymore (even
