I watch most machining channels because they are entertaining. I watch yours because it's educational. OK, it's entertaining too.
Thanks. I try to add value.
I’ve seen many ball turners but I’ve never seen it done like this. You’re full of surprises Joe!
I could have made a ball turner, but I thought you all would like this approach.
In the Navy the cannon ball holder is called a monkey and was made of cast bronze. Cannon ball were cast iron. In cold weather the monkey shrink more than the cannon balls. The saying "So cold it would freeze the balls off a brass monkey" I enjoy your channel thanks for uploading it.
I was looking to see if someone had already dropped this nugget of grammatical history. Thanks, Kenith!
This is probably a myth as the brass monkey would never contract enough to make the balls fall off.
@@modellingmark Perhaps in a heavy winter storm with extreme listing and rolling of the ship?
@@modellingmark This is a myth. The origin of the phrase is unknown.
Hello Joe. The base you made for the canon balls is called a MONKEY. Originally they were made of brass and screwed to the ships deck to be salt water resistant. The cast iron balls were then stacked as yours. In freezing weather the balls if wet would freeze solid on the Monkey. Hence the saying of "it is cold enough to freeze the balls off a brass monkey" Great outcome. Happy New Year from Australia.
I have a feeling that story came out of the imagination of some old salt who was given a hard time for being lewd.
A comment above suggests the bronze monkey (ship fittings being of bronze) shrank before the cast iron balls did, which then rolled off the monkey. I always wondered where that expression came from - this sounds plausible.
2nd step, clever. Didn't see that process coming... TY
Good morning, love the videos Joe, I found your channel by accident and learned so much from you. Can’t thank you enough.I was in an accident that left me disabled.I was a master plumber but since watching you for about 2 years now. I have learned a new skill.Can’t thank you enough. Keep the videos coming. From PENNSYLVANIA.
Stefan is wonderful! You 2 could have a great time addressing various mounting challenges! Love your relatively simple method for this project.
Outstanding work. Fixturing is 50% plus of the machining challenge.
You've taught me a tremendous amount.
Many Thanks,
Scott
Absolutely.
This came at the right time a simple way of turning brass balls as I need two for a project I am embarking on
Well done, Joe, amazing simple technique. I definitely keep this one!
Thanks for sharing 👍
Learn something every time I watch your videos sir. Great stuff 👍🏻
When in the machinist school some 50 years ago hand ground HSS tools were the norm. There was some carbide but only used rarely. Same basic rules are applied but with a negative or neutral rake. Those skills are as they are and the basic rules will never be changed but can be modified to suit the material in question. There you go with more pressure turning. I have still yet to try it. I may have to just do it to get the feel for it. All the best for 23 my friend. Take care eh ! ! !
I’m impressed! Just another example of things I wish I had learned how to do!
I needed some 0.625” brass balls recently. I took the easy way out and did the old McMaster Carr thing. 😊
Man, if the idea to pressure turn a high contact form tool had ever entered my mind, I would have dismissed it as impractical at best. Now I gotta rethink the whole idea. Thanks, Joe?
I've never had an occasion to pressure turn anything. I keep forgetting that's an option.
At one point I thought ‘now how the hell is he going to hold that?’ But then you introduced the pressure turning holders. So brilliant, so simple, so Joe Pie. Happy New Year.
Thanks.
Good shout out to Stefan, man's a legend👍 I think he gave credit to Tom Lipton /OxTools for that milling a sphere method though🤔
Great lesson in form-cutting in this video, gotta say👍
Oh, this is a super neat technique. I'm definitely trying this. Thanks for the tip!
Brilliant - what a great technique.
Glad you like it!
Interesting work holding method - I always learn something from your videos.
This is a much better way to make balls on a lathe. Lot easier than to actually add an attachment to lathe to turn balls. Will certainly put that in the "tip toolbox " and will try it🙂
Very interesting! I would have never thought that the pressure turning setup would hold against the interrupted cut like that. Certainly good information to store away in the back of the mind.
Thanks for Sharing ... Happy New Year .... Stay Safe and Well ....
Love it. Amazing work holding. Thanks, ill use that one
Nice work, Joe and now you have a set of brass balls!
ILMAO!! love the "break out in a rash" comment. Priceless. Happy New Years and thanks for all your videos.
Hi Joe, A very interesting project. I think you need to make a "triangular ring" to hold the balls. The triangle should have 1/4" radius at each corner and sized to hold the first layer of balls. Originally they were made of brass and in the British navy they were called monkeys. Hence the saying "cold enough to freeze the balls on a brass monkey"
I made a ships cannon from a 40mm Bofors "ack ack" shell that I picked up whilst on holiday in Malta. My grandad was stationed there for some time during WW2 and I have his regiment cap badge which is like a crown I have fixed this to the top of the cannon barrel to represent the crowns cast into the barrels. I think it is a nice way to display his badge.
Hey Joe enjoyed your video thouroughly previously I watched a clickspring video. Chris was making a form tool with a small radius. Didnt understand why it wasnt done your way in the first place.
I thought afterwards your Radius would of been closer to aproximate to print without the heat treat distortion and extra work Chris put in to achieve his result.
I do also acknowledge Clickspring channel and Chris is an absolute craftsman too.
Joe, great video. Just commenting to say that I was given the PMR engine lathe kit as a christmas gift, and I intend on following your lathe series step by step to learn all the little tricks you used. Thank you for the effort you put into your videos and the knowledge you share, it is invaluable to young machinists like me.
We were all young machinists once. It starts in your heart and your imagination. Go to my website and use my contact page if you get hung up on any of your parts. Now go give the person that bought you that, a huge hug.
Excellent work, after watching the second work holding set up and cutting operation. It's rather simple as long as your tool profile is correct. Enjoyed that Joe (well, you make it look simple). Tony
That was fun - great to follow that approach. Balls turned out excellent and as usual some useful tips.. :)
Great Tutorial of how to make the cutter & the brass balls.
Glad you liked it!
The 2 very best engineering tutors on YT Joe Pie & Stefan Gottswinter.
Stefan also, (like "This Old Tony") has a fantastic eloquence in respect of real English humour.
Great video Joe.
Thanks. I enjoy his material and delivery.
Great tutorial Joe... Again i can say ""Joe Pie Taught Me Something" didn't know about pressure turning! For interest, the plate you made to stand them on, in historic Royal Navy times was apparently called a "Brass Monkey". when it was cold enough on the ships, the plate buckled and the balls would roll off.. Hence the term "Cold enough to freeze the balls off a brass monkey ! Learned that on the HMS Victory tour !
Hi Del. Thanks for stopping by. Interesting how a video can spin off unexpected bits of knowledge you wouldn't normally be exposed to. Thanks for the comment. Ride safe and Happy New Year.
You never cease to amaze me with your lessons that you share….HNY, thank you
Happy new year Chuck! Thanks for stopping by.
Well done! Also nice tips on grinding your own tools
Thanks! 👍
Outstanding Joe!
I once had to make more than 1000 brass balls 10mm in diameter. Very interested in your solution - great result.
Thanks for sharing.
I hope you were on a CNC. Woof.....1000 pieces manually is a real test.
@@joepie221 No CNC. Home shop. I was much younger and the money was good 😉
Outstanding Joe
So cool. I have a 1 1/16 bore Cannon I made 20 years ago. Now I know how to make some Balls for it!
You made it look easy. Brass is my favourite material to machine next to Acetal. Stefan has gone full time, will interesting to see his progress.
Thanks for another great video. I also enjoy watching Stefan do amazing work on his Dekel FP1.
Nice lesson on form cutters and their use, Thanks. The cannon is a real beauty!
No ball busting here ...... 👍👍😎👍👍
not having access to other machinist you are an amazing resource I have wondered about holding similar shaped parts. This definitely goes in the workholding book!! Thanks much
You Bet.
🤣saying Stefan sounds like the Terminator just made my day! lol
I don't think he would mind hearing that. At least I hope not.
@@joepie221 I mean who doesn't love the Terminator!? One of the best movies of my youth. I just never put two and two together and now I'll never be able to unhear it in his videos lol.
There hasn't been a video I did not enjoy Thanks for sharing
Going to have to revisit pressure turning , haven’t had much luck in the past but this video gives me new hope. 🤔Thanks for making it look so easy.
Stefan is one of my favourites.
Thanks Joe for another excellent video! I learn something from EVERY video that you share-
WOW Joe that was amazing thank you for teaching me something new.
Any time
If you had made the cannon ball stacking base, you would have made a "Brass Monkey".
I didn't know you needed brass balls to build a Quorn! Happy new year!!
Nice tutorial - as usual. :) Thanks.
Were it my assemblage, I'd darken the bead-blasted cannon balls with any one of several brass blackening solutions for a little extra authentic look.
I may do that.
Brilliant. Thanks Joe for the video. I wondered how you were going to make them 👍
As always, brilliant video. Short and to the point Thanks for the video
Such a beautiful project.Thank you.
Fantastic technique. As always. 😊😊😊
very good job Joe..thanks for your time
Thanks for everything you do Joe, it's really appreciated.
I've picked up so many tips from your Chanel.
Glad to help
Joe the base is called a “Monkey” that’s where you get the old Royal Navy saying freeze the balls off a Brass Monkey👍🏴
You are so cool Joe. I love your videos. Such a master. Thanks for sharing with all of us mortals.
Paul
Love it Joe, great video!
Glad you enjoyed it!
Thanks Joe
Look sharp thanks for the video
Thanks for watching
I always learn something from your videos. Thanks Joe.
Thanks for watching!
You're always an inspiration on work holding!
11:32 The square "monkey" looks good in contrast to the cannon balls, but making one that is triangular is the correct style "monkey".
Don't shoot me I'm only the piano player.
Lovely work that Joe.
Another masterclass in holding a difficult shape for machining. Thanks again Joe.
A belated happy new year.
Bob
Thanks Bob. Same to you.
That was absolutely magic, loved that method superb 👍🏻
Glad you liked it! It worked well.
I come here for inspiration and you provide it. Keep up the good work.
Thanks again Joe.
Happy new year Sir, good to see you again.
Neat! The navies used brass monkeys on which to store the cannon balls. This to prevent rust and corrosion in the salt air environment. Hence to the saying 'colder than the balls on a brass monkey'. The example I saw the depressions in the monkey were spherical and not conical.
All the best in the New Year.
Very nice, great technique, nice look. Cheers
I have now learned that "Brass Balls" are made and not grown. Great job on their turning. Turned out just like the cannon and it carrage. Opinion - Blueing them would make them unique.
Trust me, they appear for many different reasons.
So one on the cannon Joe, he looks great, 👍👍👍👍
Hey Joe, Nice brassies couldn't help myself Haha. Putting this one in the Rolodex. Joe thank you buddy be safe.
Awesome I would not have believed you could that
You'll have to center the tool correctly first, but after that, off ya go.
This goes to prove it !!!!! Joe does indeed have brass balls......and can make em too !!!
Don
Great video! I always learn something new. Thanks!
You bet!
The base should be brass and called the monkey (at least in 17/18th Century British Navy)
It's where the phrase 'cold enough to freeze the balls off a brass monkey' came from as the brass contracted more than the cast iron when it got cold
You beat me to it, however it's good to see someone knows their history. 👍
Very neat! Thanks
You have a good eye for esthetics. Happy New Year!
Thank you! You too!
As an amusing aside. Pretty much everyone has heard the phrase "Cold enough to freeze the balls of a brass monkey"
A "Brass Monkey" is actually the base you stack the cannon balls on. With the cannon balls usually cast iron and the monkey made of brass they have different thermal expansion characteristics. In cold weather the brass contracts more than the cast iron. If it is cold enough the monkey contracts enough to let the cannon balls fall off.
This video taught me that. Thanks for adding to the conversation.
Unfortunately, a myth. See my long comment.
Another great video Joe. As usual, some fantastic techniques learned. I assume that the brass pieces to hold the balls for the final operation were formed with a round nosed end mill.
Initially, yes. But a conical recess will work too.
Sweet. Some powder and a ram rod is all you need now. Does the barrel have a powder hole and sump to send the ball down range? Don't forget the recoil rigging. Thank you Joe and Happy New Year.
Happy New Year Joe!!
Great pair of videos. It seems amazing that you can generate enough pressure to clamp the ball for the second stage machining.
After reading the comments looks like your going to be making a brass monkey!! If you ever get the chance to visit my old town in the UK, Portsmouth, you can see these things on HMS Victory. On the ships tour they will show that it wasn't just cannon balls that they fired, it was pieces in all odd shapes designed to do the maximum damage at close quarters!!
Good luck from Spain!!
I don't know if you have ever heard the phrase brass monkey weather....or cold enough to freeze the balls off a brass monkey, its not a rude basis it comes form the Napoleonic wars when the winters in Russia and Crimea etc were so cold that the brass cannon ball holders would shift under the weight of the cannon balls and crack dropping cannon balls everywhere .
I have made a large number of wood bearing balls from lignum vitae and boxwood using exactly this method. You can get some really tight tolerances with it too. I made some wood machinery some years back with a motor that had copper wiring and the rest was wood....didnt run for long due to heat build up but it did work lol
Thanks for sharing
GREAT job making brass balls and love the technique. Folklore tells us the cast iron cannon balls used on ships were held in a brass ring known as a monkey. Because the coefficient of thermal expansion and contraction for brass is about twice that of cast iron, supposedly in very cold weather the brass would contract much more than the cast iron balls, setting them free and thus "freeze the balls off a brass monkey". With today's technology, we now have Gorilla Glue which can be used to secure the brass monkey's balls.
You have balls of brass! ;) Many thanks for the tips!
for rounds to actually use... discovered that i can roll lead into fairly good spheres between two pieces of flat plate. i start with cast balls, flash removed to make things easier. this also work hardens the ball which has it's uses.
Happy New Year mate
Happy new year!
Thanks for sharing 👍
Nice balls!
Solid Brass to boot.

Beautiful!!
Thanks. Almost done.
Perfect Joe👍👍👍
Hi Joe,
I have seen where people pressure turn that they use something, like some leather or cork, as a from of clutch to prevent marking of the part. In the "jaws" you made was it just the edge of the hole that supported the piece or was it shaped to follow a small part of the sphere to get a greater contact area or a tangential surface rather than a potentially sharp edge?
Great video as always,
Regards Dennis.
It looked to me like he had machined hemispherical dents into the tips of those pressure plates. If the radius is the same that should give a lot of grip surface, and not much chance of marking the part, unless the part slips.
