What you and Quinn can do with bench top lathes and mills is quite astounding. I have very large lathes and mills at my disposal but I never have enough time to do these types of projects. I’ve been relegated to buying most of my tooling due to these time constraints. I shall machine these fun projects vicariously through channels such as yours. Great work!!!
Cool! I like how the button cutter (20:32) ends up leaving a radius in the final part, where the travel of the cut ends (see 24:10). That's not always what one would want, but it's perfect for this usage! Nice smooth transition between sphere and cylinder. Nice work!
Very nice job with the limitations of a mini lathe' you can get longer tool life and better finishes with lower speeds with high speed steel. Machining is all about speeds and feeds. I've been a machinist for over 40 yrs. Over all good job
Great video as always, Here is some unsolicited advise, ignore it if you want to, would recommend placing zinc plated steels in a container with vinegar so that way the acidity of the vinegar will strip the zinc off whatever steel and save your lungs when welding, plus wire brushing the schmutz/residue that it leaves behind after the vinegar bath.
I've never seen a ball turner mounted that way, it makes a lot more sense for a mini lathe as you don't need to worry about the tailstock getting in the way
I have to say, I believe it's traditional to turn two brass spheres first, so as to be able to respond affirmatively to questions about your courage. Good project, doesn't just let you turn spheres, if you use the compound to angle the rotation of the tool, you can turn all kinds of conic sections, ellipses, and so forth. Say, should you ever need a doorknob or drawer pull which is not a perfect sphere. It's been a while since I did the math on those kind of things but I think a bit of trial could get you some very fine results.
Bruce here,Again a great project beautifully presented. My suggestion is make a powered hacksaw.I had one and sold it once I acquired a band saw and wish I had it back because you can use blades that are much cheaper than bandsaw blades and it seems to be a great compromise between doing it by hand and a much more expensive and complicated machine. Thanks for what you share on UTube.
I tried to add a dropbox reference to pictures of my 3D printed ball turner (design model and guide to making the real one), but youtube didn't let me.
Very well done video with impressive and creative machine work. One thing I'd like to see in the mill work is how you do the setups, I'm new to the mill and I think it would be helpful. Thanks for your outside the box ideas and projects.
Really nice design and well executed (as always). I have a ball turner like the 0:25 design and whilst it does the job it's hard to adjust the radius accurately and it's not very rigid when there is a lot of tool stick out.
It's not his design. It's a well known technique. He doesn't like to admit that he copies most of his stuff from RU-vid videos, in this case from ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-1AUPBj8cBQ8.html&ab_channel=AdeSwash
Nice work. Making a tool to finish off a tool.. I remember doing my apprenticeship, and all we had for a ball turner was co-ordinated left and and right hands on the saddle and cross slide! Many a tulip or mushroom where shaped....
Curious, what if you were to drill this accurately full of holes before making it into a ball like one would do on those 1"x1" cubes with 100 holes. Wonder if it would still machine normally or be a total mess.
Love it. There's some great info in there and I love the mini trolling with the hacksawing and even leaving the stalls in. I know I get lots of stalls with my lathe.
A note about thrust bearings: the two races may not be identical. One will have a precise I.D., and a slightly _under_-size O.D. The other will have a precise O.D., and a slightly _OVER_-size I.D. The first is meant to turn/spin with whatever passes thru the bore, with clearance for the "outer" object. The second is meant to turn/spin with the outer object, with clearance for whatever passes thru the bore. This is because the two races always turn in opposite directions, relative to each other. I discovered this when adding thrust bearings to the compound of my mini-lathe. In this case, one race turns with the cross-feed screw, but must have O.D. clearance so it doesn't bind against the compound. The other race contacts the compound and does not turn, so it must have clearance for the cross-feed screw to turn freely. Now depending on the application, it may not make a difference in practice. But, it's something to be aware of.
Nicely done. Maybe you like the exercise but a power saw (as others have suggested!) You could cheat and show using your trusty hacksaw and finish the cut with power. Hand held bandsaws are relatively cheap & can be converted to vertical if desired.
This is what I got a lathe for really, was to turn ball shaped objects among other things - but my main project was to make a shifter ball for my car lol I've seen a lot of different ways of doing this. From just a simple turn table to a tool post holder for a boring head. Always interesting to see how people tackle this type of tool. You should make a handwheel to attach to your powerfeed gear since you don't use power threading often. Seems like that hex key has to get annoying / painful to use after a while.
I've commented before on this project and I'm back considering the task myself, without the lighting and camera setup. I must say that I really appreciate the way you break your videos into chapters for ease of reviewing. Not many, if any others I'm subscribed to, do this. It's just one long video usually. You never mention plans and I was wondering if you work your projects as you go or do you actually have plans or drawing that you follow? After all, we all know that sometimes the finished item is not the fist attempt but the 3rd, 4th or Nth and drawing or plans would surely cut down that trial and error. Thanks again for your time and responses.
I have to admire your ability to do all of these projects from scratch. These days, I tend to buy as much of it as I can. So I would have bought a cheap boring head to use for it and made the rest. The only thing I find that makes me somewhat cringy is that there is no way I would hacksaw everything the way you do. That’s just too much for me even though I’ve got three hacksaws.
Thats a really clever solution, and extra cred for making it on a quick change tool holder so you can install it on the lathe in a few seconds. Well done, and really entertaining video! 👍😁
That's Schmicko! With all the moving parts which could cause chatter it really came together well. By the way did ya know bees are allergic to honey? They break out in hives....I'll see myself out!
Nice build, handy tool! I do like the fact that you used a round cutting tool, this will make set ups much easier. I will be making this for my machine, just a tad bit larger though, thanks for the inspiration!
ROFL - plaster based Spakfiller. Now THAT is rough as guts! Wish you'd file off the gnarly tops of the threaded studs on your quick change height adjusters!
I've had it work before without issue, but this stuff was a bit old and had a pretty chalky finish. The finish really doesn't bother me to he honest, I can always replace it in the future if I want to. Cheers
@@artisanmakes - buy some Builders Bog from Bunnings. Just get the small squeezy pack as it tends to go off quickly after opening. It's just a 2-pack polyester filler like what the yanks call "Bondo".
Have you ever thought about taking the blade from the hack saw, streching it out and welding the ends together? You could then place a couple of wheels one over the other and place the blade over them? Just spin one of the wheels and blade would recirculate itself?
Hi from Australia, great chanell. We have a saw in Australia called a band saw and they work great for cutting through steel etc. Ha Ha. Great I like watching your videos. Regards Merv
Very good stuff. I have never seen your channel before. I hope to get a workshop built soon and buy myself a lathe. I live in Thailand so I think it will have to be an Asian lathe because of the cost of shipping from the U.K or Europe
Interesting design, it's new to me. Using a round insert makes for a nice transition. The only thing I would criticize is the use of the thrust bearings to not only take the thrust load, which they are made to do, but also locate the rotational axis against radial loads, which it isn't meant to do. It really should be done in combination with some form of bearing to make sure the axis of rotation remains true. Seems to be doing a good enough job for your purposes, but maybe something to keep in mind for future projects.
# 1 you need a portable band saw and stand young man. Don't know if you have Access to those kinds of tools down there total cost US is about $89.99 to $109.99 for the saw and $99.99 for the stand. Use the saw by itself or put it in the stand and use it like a band saw. Best of both world's 😊
