Re: steel alloys
Jim E.
If I know what it is, I somehow keep track of it, even the cutoffs.

This may be by label or segregation. Mine is stored in a shed. My philosophy is if it can rust, it will. I once sprayed some 12L14 with rust preventive, still had surface rust, so I just accept it. Same with corrosion on certain Al alloys. I haven't a clue what the colors mean, if anything. Graciously, Jim Lakewood, CA All Hail Rube Goldberg! Richard Kleinhenz wrote:

Re: Collett Chucks and Band Saws
In the US, Harbor Freight sells some that cost quite a bit less than $450.

steel alloys
Richard Kleinhenz
Basic question: When you buy steel alloys, how can you tell what you have? Is there any kind of color coding? Sometimes rod has some yellow or blue color on it. Is that meaningful?
Secondly, if you bought some stuff and don't use it all - do you write the alloy on it with permanent marker? Or is there some way of tell what you got? I don't mean telling stainless steel from aluminum, but 12L14 from 1018 or drill rod. How do you store it? Inside, of course, in a 'dry' basement that is unheated and not all that dry. Do you keep the alloys separated? Make up your own color coding? Do you wipe some oil on it to help prevent surface rust? Looking for ideas! -- Regards, Rich ======================================== Richard Kleinhenz mailto:woodnpen@... ======================================== |

Re: QCTP question
jvswan
Thanks, everyone, for the suggestions. I would really like to make
one of my own, but that will likely have to wait until I have more time. As a hobbyist, I guess I have to choose my projects since I also have a career, family, other hobbies, etc. I got some rudimentary experience with a Unimat before moving to the 7 X 12, so I'm also looking forward to getting better at this. Anyway, I might just spend the money on other things like the four jaw chuck (as Bob Streimikes suggested) and some collets. I can see how cool the QCTP is, though. So, I'll just have to see what happens. Thanks for all the replies to my query. Jason --- In 7x12minilathe@..., "jvswan" <jason@v...> wrote: Hi:the benefits of a quick change tool post.

Any comments or suggestions would be reallyappreciated.

Please recommend some booksThis is exactly why I uploaded the file: < ead.txt> Download it, print out a copy, and take it to the lathe. Useing something that is easy to machine like PVC pipe or aluminum conduit, practice, practice, practice. At first, read each step as you go. Then when you feel more comfortable, do a few steps at a time, until you can do it in your sleep. The method works. I learned to thread using it. You can buy ER4/5/6 or EL4/5/6 (size to fit your lathe) as cemented carbide or you can grind your own HSS tools. I recommend you grind your own bits for practice, using one of the carbide ones as an example. Don't forget to leave clearance for the helix angle of the thread. Don't try to cut threads using one of the el-cheapo carbide bits. You will be frustrated because they seem to have no clearance on any edges. Hope that helps, RA |

Re: QCTP question
kf4zgz
Hi and welome to the mini-lathe world. I would also like a QCTP, but
like you, I spent the money on other tooling. Here's a thought.....If memory serves, the HF mini-lathe requires a 5/16 tool. I bought a rather large assortment of HSS and cobalt bits on ebay. Only 3 or 4 were 5/16, the rest were 3/8 and 1/2 with a couple of really BIG'UNS ( 3/4). As I use, need or have time, I sharpen the used bits. I also take the time to grind down the top so that the tool is the correct height. Voila! quick change! It really doesn't take that long to loosen and tighten 3 bolts. For example: among the lot was a cut-off tool ground from a 1/2"x1/2"x3" tool. I just took about3/16 off the top before sharpening. This makes a very stout cut-off tool. -btw- the QCTP design I have in mind is on hold until I get a mill! Matt one more -btw- I get the added benefit of practicing my grinding skills. |

Hi Jason,

Not sure how big a hurry you are in but since this is a hobby group I will assume you are in it for the fun of it and recommend you consider making a quick change toolpost of your own. The pattern I am recommending is usually know as "Mert's toolpost" in 7X10/12 circles, although it is not new with him and indeed there is a commercial toolpost out there that uses the same concept with the addition of angular indexing . See: and various references to "merts toolpost". These things are dooable at the rookie level and you will learn a bunch making one. Please note, you can make one of these without a mill but you will need a 4 jaw chuck (a much better use for hard to come by dollars since the stock tool post is quite usable and easly replicated you you want to change tooling quickly.) I made mine from 1.125 dia steel shaft and 1X1-1/2 hot rolled steel bar. Regards Bob Date: Mon, 07 Apr 2003 17:47:07 -0000 |
