    Cutting tools

    My uncle is a mechanic and has ran his own shop since he got back from Vietnam. He has a lathe and mill and is pretty knowledgable with machining. I'm sure he's more than willing to teach me anything he knows. My neighbor who's garage I use to store my tools and forge has also worked a job with that kind of stuff before and has a lathe at his other house in New Mexico, he actually has some cutters in his basement here he said he was going to find for me. I'm not too worried about getting first hand experience since I know people who can show me. I mainly want to get a book to have a quick and easy reference for things like tolerance, threading, grind angles and all that stuff. I've seen on "This Old Tony's" youtube channel he references to one of his machining books every time he does a project when it comes to things like the cutters you need to do certain types of threads, or for cutting gears on an indexer, tolerances permitted on certain things, can't think of anything specific at the moment though. As for a community college, I'm not sure there is one around here although I've never searched for one but I've definitely never heard of one. I know there is a vo-tec school but they charge for classes. I'm not interested it paying for classes right now, as I've only got a little 6 inch atlas lathe I'm just trying to learn and mess around on. I would like to take one eventually if I can get the equipment and money to turn this into a career. Which is my ultimate "dream/goal" which is a long shot for me at the moment but I know I can make it work out with enough time, money and effort. Also, I just learned what a turret holder is for a lathe about 2 weeks ago. Those things look awesome and I'd probably want to get one when I get a nice lathe. Definitely seems like that the thing to have when you're doing any kind of production run if you're doing more than one of the same parts.

    Thanks for all the replies, I've been a little busy and no on here for a bit. I've watched some videos that show about the geometry and purpose of the way the cutters are ground. So I have a lets call it, very basic idea of the gist of it. I'd like to make up a jig for getting the right angles on my bench grinder and get me a good wheel for it. I've not done anything with it for about a week but I've pretty much got my lathe all back together, I just have to order a piece off of eBay that I broke trying to get the handle off the top slide of the carriage. Also would like some new handles cause the middle one was replaced with a crappy round plastic piece and the top on was broken and was difficult to operate. Although it ran as it was when I got it, it should run like a dream comparatively. I found a set with a quick change tool post, 5 holders, 5 cutters (turning and facing), 9 piece boring bar set, some center drills, a chuck and another few odds and ends. Priced at $232, I figure it's well worth it, although I could just get the quick change post and the 5 holders for $164. I'll have to check some prices on everything it comes with and compare if the whole set is worth it or not. I figure it's at least not a waste of money for a nice beginner purchase to have a little of everything though. Also, what would be the best all around book to buy on machining? I've heard of the Machinists Handbook before but I'm sure there are others. I'm sure they can get pricey as well, although I'm not too concerned with price whenever it comes to having something that could teach me for a lifetime. I would like it to be not super complex though, something I could pick up and understand after a few reads preferably. I'd hate to buy a book and not understand any of it, as if it's another language all together. Knowing me though I'd end up buying it in another language and not realize it for a few pages. LMAO. and again, I appreciate everyone's input. Since my journey started in blacksmithing I've realized I love all metalwork. Trying to save up for a mill I can revive next
  3. I've actually thought about using a 55 gallon drum and digging a fire pit to make my own charcoal to tryout. I've watched some extensive videos on the process and read about it. Doesn't seem too difficult to do in small quantities at least.
  4. This may not be the best place for this, although I'm sure someone can give me a little info. So there is a 12x18 Starrett Pink Granite Surface Plate on Craigslist for $50, I looked it up and the cheapest I'm seeing one is $668 for that size. Is a granite plate suitable for work in the metal/machine shop? I'm pretty new to all this stuff and I honestly doubt I'd get any real use out of a surface plate right now since I'm not machining anything that has to be super precise. Although for $50 I don't think I can pass up the offer. Also if it's gone a little bit off of true, how hard or expensive would it be to true up again?
  5. Got most of the Atlas 618 painted and put together. Just need to paint the part that the motor and motor pulley mounts on.
  6. I figure my uncle knows how to sharpen them. I've watched some videos on it so I have the idea. I'll need to get a good plate with some angle reference on it.
  7. I met my dad today and he brought me in a nice haul of goods. This cast iron belt/disc sander frame. Ended up paying $25 instead of the $50 asking price. Some oil cans. drill index full of bits, most look un used. All the paper packs have drill bits in them. Some look like they may be for a mill. All new. Cigar box will be nice for organizing. 3 combination squares, big clamp, tap wrench, Swedish needle file set. Clamp is drop forged USA made. Don't remember what brand was. It's heavy duty though. blower, might be a nice replacement on my coal forge, maybe not. Some files and a screw driver or two. A nice looking bench grinder. there are two boards, resin/epoxy with some kind of fiber in it. Not sure exactly what it is though. Sorry for such a big post, it's stuff my dads been getting for a few months for me. If needed feel free to turn into its own post. Didn't think about that at first.
  8. I like that your vise is mounted to a 55 gallon drum. I'd say that's a good excuse to always have some scrap. "If it wasn't full of metal it would fall over!"
  9. I've always had a fascination with taking things apart and putting them back together. I'm not sure why.
  10. If it stops working and I ask when I should change it, my brain may be the one not working. The only reason I even asked is because it was a pain to do the first time, wasn't sure if it would have anything bad in it so I took it away from my yard.
  11. Yeah, I didn't think about that the first time I took them out. I got them all the way in and they looked a little wonky. I felt stupid to think they didn't have a specific order. How so you like my home made chuck key? Used a bolt and some rebar.
  12. I didn't think of it throwing the grease out. I got it all put back together, it's moving super smooth now.
  13. The part that holds the metal.it comes apart, it's from an atlas 618 so it's old. They might not make them like this anymore.
  14. So in the process of restoring my lathe I got the chuck completely apart. Should I just fill it with the oil I'm supposed to use to lube it or should I put some grease in before I seal it all up?
  15. Alright, I've only done small parts so far. I changed it in between two of them, the rebar was fine though. I've gotta get the paint off the rest to do the big stuff.
  16. When should I change the water after electrolysis rust removal? Not sure if it will eventually stop removing rust or what. Should I just add more wash powder and that would be good or should I switch the water completely after a day or so?
  17. Yeah, they were originally old rusty rebar. With all the time i spent cleaning them up I`ll probably just go buy a 20 foot piece of rebar and cut it to lengths and put them up where they wont rust. it was a huge pain since they have that texture. i may eventually just get some square stock mild steel and that would be easy to clean with a flap disc. I`m loving it though, its working beautifully. The lathe will be good as new in no time now.
  18. I got mine on amazon if that's available in Argentina. Like $22. Search butcher block brush, the brand is Winco, it's really nice
  19. Finished setting up my electolysis setup a bit ago. Having some coffee and a cinnamon roll while I wait. I think I made a pretty nice setup. Ive got some .175" thick copper cable, solid, I ran it around the tote and back in around rebar. Boy was it hard to bend after a few bends. Work hardening is real folks! There is one piece of rebar in each corner, I then tied the rebar to the thick copper with some actual copper wire. (I've got a lot of copper in a lot of shapes in sizes.) I changed out the wood for a plastic pipe and put a bolt through it. I also put put tape around all the exposed copper wire except where I attach the battery charger I had to turn baking soda (sodium bicarbonate) in soda ash/washing powder (sodium carbonate) via my oven. Since I forgot to see if they had any when I was at the dollar general.
  20. So i opened the drawer to see if the snake was in there still. It was, along with another one. So yeah, now im constantly looking at every crevis very carefully before i go near or touch it. Awesome....
  21. I'd love to do a 2x72 but Im not gonna dish out $500+ for one and I don't have the need to put the time and effort into making one yet. Although I do plan to make one when the need arises and I'm confident enough with my fabrication skills.
  22. How do you know if the belt will hold up? Are the rated at the belts RPM or SFM? Also, don't have a motor but I could get a decent one cheap. Or use one from a machine I don't use much if needed. Also, I was thinking $50 might be steep but not sure. I'll check the belts though. I can't find any belts for that size. I checked the first custom belt place I found on google though and for aluminum oxide for $6 each and ceramic for $13. Rated for grinding metal. Not as bad as I thought they would be since it's custom. Also the price drops the more you buy. I told my dad to get ahold of the guy (he's in Ohio where it's posted) and to try and talk him down from $50. If he does get it for me I'll try and find someone to sell my 4x36 sander to for $20 and then at the very least I'll have a better sander. The one I have isn't something I really enjoy using.
  23. So I found a Toolkraft 6x28 belt sander with a 9 inch disc sander attached, they want $50 for it and there is no motor. It looks to be made of cast iron and from the 50's or 60's. I have one of the newer cheapo 4x36 or 32, whatever it is with a disc sander. It's alright for wood and touching up metal. I was wondering if you guys think it would be smart/able to make it spin fast enough to be at belt grinding speeds. In one of the pictures you can see a lock screw to take the disc off, so when not needed I could take that off for extra speed. I'd say I'd want to get some new nice bearings and maybe make some rollers for it if I wanted to try that. Here's a picture of it though, think it would be cable to do that with? Here's a picture of the back It also rotates like any other like this, didn't want to post too many pictures though.
  24. So I took my lathe apart (Atlas 618) in order to clean it, one I get it all cleaned up and stripped of paint I'm gonna paint it purple(as seen below). I also ran into a big black snake in a drawer looking for something. It's about 4 foot long, maybe a little shorter but it was big. Opened a drawer to see this about gave me a heart attack.

    I've got family up by Columbus. In grove city. Maybe I'll ask my aunt to check it out for me before she comes down next time.
