Gregor, while I am no expert, generally there are three terms that are used in heat treating - annealing, hardening , and tempering. each metal has its own specifics but for example for o-1 ( aka oil

Very useful. Thanks. -JC

I made up a cheat sheet for setting the RPM on my minilathe for various materials and diameters, and thought some folks here could use it too. Here it is in PDF:

Another question from a beginner. According to a basic book about home machinery it is possible to temper metal using a MAPP gas torch. I have tried this on a 4x1/2 punch made out of annealed 4140

--Hi Rance, Not sure where your looking, but in the 2007 Grizzly catalog (pg.614) they are $2.95 ea. I bought three, 1/32,1/16,1/8 with a 7/8 hole a few years ago when I first got my mini mill, during

FYI, check out the GrizHFMiniMill mailing list. I find it much more useful then the minimill list. http://groups.yahoo.com/group/GrizHFMinimill/

Greger I have owned the mini mill but not the micro mill. depends on what you are interested in as far as projects. personally, I think the mini is as small as I would ever go, actually I ended up

Hi Ian, See my responses interspersed. wrote: We do have a lot in common. That's my situation too. I haven't had much call for OH&S awareness thrust at me in this role. Pre 2003 I was middle managing

Gregor: There's a bit of information regarding the HF mini and micro mills over on the C-O Lathe group, listing the pluses, limitations, etc. Come on over and have a look...

G'day John. Firstly, I am not retired and out of it, I have my own engineering consulting business of which I am both director and an enployee, it supports my other activities. My thoughts still stand

Hi: I just joined the group. I only recently became interested in home shop machinery and have been doing some lathe work on my 7x12 Cummins. I plan to buy a mill in the near future. Does anybody have
