A small attachment can be made to fasten in the tool post of a lathe and the attachment made to take a mandrel on which to place the blank for cutting a gear. I'm thinking that will be one of the first things I'm going to get for this Atlas but it will have to wait until my ship comes in.When in need of small gears for experimental or model machines the amateur usually purchases, never thinking that he could make them on his own lathe. I did replace the old tool post and put a QCTP that I got from the Little machine shop and that made a world of difference with that machine. I also have a small Cummings 7/12 mini lathe that I use a lot with small stuff but that too is lacking with the amount of tooling I have been able to buy for it. I still need a lot of tooling for that too but I have more tooling for that than I have for this lathe. There are a lot of other parts I need to make for this stripper but I think most of which I can make with my mill. The bar I finished ended up ok but the finish was rough which really doesn't matter because the rough surface will probably help hold on the the wire better so it will grab the wire and pull it between the two rollers easier. I finally found a sweet spot where it would stay in place but would still slip at times and I would have to start all over with the setup. The tool post is the lantern style and I'm guessing it is worn out because I had a really hard time getting it to stay tight and not slip when I started turning. I might have some of the 1/4" ones in carbide somewhere in one my of my huge stacks of stuff I have laying around. I have some carbide cutters but they are 5/16 and the only tool holder I have will only take 1/4" tool stock so I've got to figure something else out. I did manage to get one of the bars cut down to where the bearings had a nice close fit but the other one must be a harder material because it didn't like to be cut with what I was using. I didn't have a way to use a dead center at the chuck end so I used the 6" 3 jaw to hold the piece on one end and I used a live center on the other. That's going to cut down on the size I had planned so I guess I'm going to call it a mini stripper. With my Bridgeport I could only get a piece 14 1/2 inches long clamped in my vice where I could mill the ends and then center drill them. I wanted the pieces to be about 20" long but I don't have a steady rest to hold that long stock on the lathe bed so I could clean up and center drill the ends of the stock. I'm building a wire stripper and I need to turn down the ends of these two pieces of 2" round stock on each end to 1" for 3 1/4". I've got like a million questions to ask about this machine and figured this was as good a question as any to start off with. I put it in back gear to try and slow it down a little and it did slow it down but it's still the same ratio between the feed and the spindle speed.too fast on the feed. It almost seems like the feed is turning about the same speed as the spindle. The way this thing is set up is like nothing I have seen in any of the thread cutting charts. What does the letter after the tooth number mean, are they a different gear all together than the gears that just have the tooth number like 64 or 64A? The thing I'm wondering is, on the threading charts they list gears like 48F, 64F, 64B, 24, 56B for instance. I've been on e-bay all morning looking around for some deals but didn't see much at what I would be willing to pay.
Cutting gears on atlas lathe manual#
The machine came with what was supposed to be a complete set but looking at the gear charts I see that the gears I have are no way near enough gears to put together any of the setups on the gear charts I have looked at in the threading manual I downloaded yesterday.
I did a little reading that led me to looking at the gear setup and possibly changing the gears to slow it down some. I could manual feed it and it was leaving a smoother finish but still rough. When I started to turn the stock it I could tell right away that the carriage feed was way to fast because when it was cutting the stock it was leaving lines, like threads as it was cutting. This is when I found out about change gears.
After I got the machine set up I decided to chuck up a piece of stock and try my hand at making a few chips. Now let me get this straight right now.I am no stretch of the smallest bit of imagination 'a machinist' of any sort, just a wannabe machinist at best. It cleaned up nicely and I mounted it to a large machine table that I built just for this machine. Months later I had some time so I decided to set the machine up in my new room that I built for my machine shop. I was really busy when the guy brought it by and didn't have time to go through the boxes. It was supposed to have all the accessories and a lot more junk to go along.
I bought an old Atlas 10F machine that was supposed to be a good deal but turned out not so good of a deal after all.
