Arnold's Design I would like to make a suggestion that will decrease your set up time. Replace the solid dowels used for the pivot pins with hollow dowels, with the lower dowel having a thicker wall than the upper. Then you can use a stepped pin that simply drops in from the top to set the radius, no disassembly required. Thanks for your excellent videos.

About 40 years ago I figured out how to generate a sphere on a milling machine with a boring head. They come out perfect every time.

[@curtisroberts9137]

You don't by chance plan on making a video of this? I'd enjoy seeing that!

[@tracylemme1375]

Curtis Roberts sorry but I don’t do that. But just a hint. A circle of any size can be inscribed any place on a sphere. Use a rotary table and a boring head with the tool facing inwards for a convex sphere, and outwards for a concave sphere. Be sure that Axes of both the spindle and rotary table intersect. You will be impressed with the surface finish.

[@kempaswe4022]

I used to work at a 100yo workshop and We never said no to any customer. So we made a lot of special tools. It was really funny, too bad the company doesn't exist anymore and that the new owner sold everything to scrap. We had 5 lathes, 2 milling machines, 1 gear cutter, several different drills with 1 to 4 chucks, axial drill etc. Everything went straight to scrap, I had known it before so I would have bought some. We had several hundred different accessories for lathes

[@ronvonbargen8411]

Nice job on the tool. I have always used a boring bar in the mill with the part in a dividing head set at the correct angle, so the center of the ball is in line with the O.D. of the shaft. And feed up with the knee adjust diameter with bore head.

[@ArnoldsDesign]

Interesting. I'll have to try that.

[@ronvonbargen8411]

Just to clarify. After you feed up to center line you spin dividing head. Depending on ball diameter you might have to adjust bore bar several times.

[@AngloSaxon449]

I used to work for an engineering company called somers forge and I've got to say you are a good turner

Thanks, I do use that from time to time. I also have a spray bottle with off-road diesel in it which works too. Off road has high sulfur, but I don't know if that helps with machining AL or not. Probably not.

[@xaytana]

I'm amazed about the amount of people that didn't know about this tool. There's commercial ones available, and Adam Savage has shown off one in a video he did on Tested with Michael Stevens from Vsauce. I've seen people use a boring head on a tool post fixture using it's adjustment for the sphere radius. Seems like it removes the issue of having a long arm that could run into the jaws of the lathe, but introduces the problem of having to adjust the boring head at the tool.

[@PhaseConverterampV]

Nice work. We made one that had the same operation, but to set the tool radius from centreline , we machined the pivot pin to the center in the mill, laying horizontal in vise, for the last .25 inches. then you always have a surface, Top and bttm pins, to place a depth mic . Then you just dial in your radius on the depth mic, and lock the set screws onto the cutting tool. Hope that makes sense. Thanks for posting.

[@ArnoldsDesign]

Thanks. Yes, that makes sense.

[@ArnoldsDesign]

I've done that too. We used to use a hook too, and leather gloves when we were cleaning out the chip pan at the end of shift.

[@cosmiccwonder300]

Cutting your hand with stringy chips seem to me to be the initiation of the machinining industry :)

[@ArnoldsDesign]

@@cosmiccwonder300 My personal initiation was being forced to quickly unwrap heat treating foil from a dozen or so 4"x4"x10" S7 blocks at 1750°F and put them on the fan. Even with thick heat treating gloves on and tools, the tops of both my hands were covered in blisters for several days and hurt like hell.

[@michaelb4060]

Very nice work. When I was looking at getting a lathe I decided to go with low entry level Prototrak CNC since the price was not that much more than a good near new condition manual lathe. Doing things like this and super easy threading operations I have become incompetent with a manual lathe. Add to it dumping G code for more complex things that seals the coffin on my manual lathe competence. I am near unemployable now.

[@JR-jq6dd]

Good job. Back in my days in the navy, we used a much larger commercial radius cutter. We used it for weld repair of stellate clad spherical steam valves on nuke subs.. Fun stuff to cut.

[@ArnoldsDesign]

Thanks. You certainly earned your money turning that stuff. I've turned hastelloy, vascomax350, aeromet, etc. They're pretty bad too. I never would've imagined that sub valves would see wear like that. Did the steam erode them?

[@JR-jq6dd]

Arnold's Design High pressure steam cuts like a laser. It would cut grooves through the valve surface. We would undercut the spherical seat, have it welded up and recut the interrupted stellate weld repaired surface.

[@ArnoldsDesign]

That's amazing. I had no idea steam could cut through an ultra tough alloy like that.

[@JR-jq6dd]

I let auto-correct influence my spelling. The correct spelling is "stellite". Also I heard brooms were used to search for high pressure steam leeks because it could cut your arm off. Hearsay or truth, I couldn't say, but I am inclined to believe.

[@ArnoldsDesign]

I knew which steel you were referring too. I think using a broom would be an excellent idea actually. I wouldn't want to go anywhere near super heated steam.

[@paullevine1813]

We have one of those old sphere cutting tools we used to use but now with the CNC'S this is much easier by a longshot . If you need to make multiple parts your tool will do the trick. As most tools & fixtures the time you spend making them does pay off in how your parts will look when your done. Not to mention they will last & repeat each time you use them. Oh & thanks for not calling it billet aluminum lol..

[@ArnoldsDesign]

I wish I had cnc.

[@WarrenPostma]

That is really cool. I want to make some machine handles this way, and then knurl them.

[@ArnoldsDesign]

Thanks!

[@ala068]

Although you touched-up on the safety aspect of your setup, please check out the Sherline video on ball turning. They use a similar tool on their minimum lath, but their setup is in my opinion safer, faster and more versatil, as the tool is only reaching 1/4 of the ball and can cut both concave and convex Cuts... Worth considering, especially when you are virtually almost there with your tool.

[@Thelemorf]

It's fun to see how few that uses the micrometers in a correct manner (hint: the ratchet knob has a purpose)

[@ArnoldsDesign]

When it's your personal mic that you've used for years to hold +/- one or two ten thousandths, you develop a feel and you don't need the knob or friction barrel. When it's a shops community mic shared by many toolmakers or machinists, then yes, you need to use the ratchet or friction barrel for consistency, because you have no idea if your feel matches the feel of the guy who calibrated it. Hopefully the person doing the calibrating had enough brains to use the ratchet, though I met one once who lacked those brains. Unfortunately, he was also my brainless boss.

[@stevenconnor4221]

Agree wholeheartedly it's your mic and your touch / feel.

[@steveattree8757]

I think thelemorf is a knob himself trying to show off.... Just because you know about the knob doesn't make you a precision machinst... Also if you wanted to be a dictator perhaps you should mention that there are specific tips for the mic just to measure rounds....

Looks pretty cool. I wonder if an adjustable stop could be added so you can run it close to the chuck without worrying about catching a jaw if you move the handle too far

[@ArnoldsDesign]

Thanks. Good idea.

[@marianodiaz461]

you can make a removable setting block to butt against the flat end of the swing fork , that way you don't need to remove any pins to set the radius

[@pieterbotes8938]

I was reading Thelemorf's comment on using a mic correctly. I fully agree with him and I can make this statement because I'm a qualified metrologist (27 years). For those who don't know what a metrologist does, I will explain: There are two types of metrology - electrical and mechanical. I'm on the mechanical side. It involves the calibration and certification of equipment under controlled environments to ISO (International Standards Organisation) standards. Here I'm talking about measurements up to five digits after zero. In this trade you learn how to use measuring instruments correctly. Take the mic. It's got a ratchet at the one end. There is a purpose for this item. It's to apply the same amount of pressure every time you take a measurement. A mic should not be used in any other way. A knife's blade is used for cutting stuff and not to remove screws from a piece of wood. Plain and simple. Everything has it's purpose.

[@ArnoldsDesign]

Maybe you didn't mean it this way, but this is aggravating. If you don't mind, I prefer that you didn't lecture me on this, because I've been in tool and die for the last 26 years unfortunately. I say unfortunately, because I'm good at it, but hate it with a passion that can't be put into words. Part of the job on many days is inspection. I've mic'd a serious amount of work within +/- .0001 with these particular mics. I've cut, smashed, and drove more slivers into my fingers over the years than I care to remember, and have milled, turned, burned, wired, form ground, lapped, polished, and measured thousands of parts, from splines to gear forms, three wires over God knows how many thread forms, including acme's. I'm well aware of the torque limiting devices on mic thimbles. The gentlemen in the metrology depts I have worked with in the past who put the calibration stickers on personal mics didn't dare make adjustments or reset zero points on any of them, because the tool men I've known would've ripped their balls off, and justifiably so. They only verified the instrument's precision. It was up to the toolmaker to provide the accuracy, and they left that to them.

[@t.d.mich.7064]

As a retired 47 year die maker/ Machinist, I can tell you that after making 10s of thousands of measurements, I would put my sense of "feel" up against any "ratchet" on a micrometer anyday!

[@pieterbotes8938]

@@t.d.mich.7064 Brother, it's your free choice to use a mic in this fashion, but that doesn't make it right, irrespective of what your perception is. By the way, I'm also a toolmaker (RED SEAL) for 46 years.

Very nice idea. Cutting internal radii will be much more complicated.

[@ArnoldsDesign]

Thanks. I haven't tried a concave cut yet.

[@brianwood6788]

A similiar jig with the tool facing the opposite direction would do that wouldn't it? Then again, I was told in High School not to never touch a power tool again as long as I lived. so I could be wrong haha

[@pieterbotes8938]

Producing big radii is chicken feed (convex or concave). Producing small (very small radii eg. like +- 0.2 mm) is much more challenging. I think that an internal radius becomes much more difficult, especially in a confined space - the inside of a bore (like a pipe).

[@productivechaos4796]

Very nice results. I am fairly amateur still and own a little Atlas 6x18 . Is there a way your plans could be modified to fit the clearance of a small lathe? It looks too tall as is. Also, can it be used to cut other radius' such as a barrel or egg shape?

[@wetwipes8179]

I got an ad before this video. It was the entire fucking LEGO movie

[@robstirling3173]

Ref the ball pins for the ultralight, If you had removed some material from the centre of the ball curve, you could have left more material at the junction of ball and pin in the form of a larger radius at this stress raising point, while having a stronger/lighter ball pin. Also on the internal bore of the pin, do you have a curve at the end of the blind hole or is it another stress raiser?

[@ArnoldsDesign]

The hole goes clear through the stub. The stub to ball junction has a 1/8" radius, so the stress riser isn't going to be bad, especially with the wall thickness I've left. I don't know what you mean by removing material from the center of the ball curve.

With cutting internal radii (my previous post) I mean the following: Let's say you have a hollow bar or pipe type of job and you want to cut a radius at the end from the inside to the outside. Obviously the smaller the radius, the worst the situation becomes. There must be some solution without fancy expensive machines.

[@ArnoldsDesign]
