- Woodturning a perfect wooden ball or sphere. No expensive jig needed
I show my Step by Step method of how to turn a wood ball.
This method is fool proof and simple. Only simple cuts needed.
I use standard wood turning tools and no jigs
I show my step by step methods to layout and cut a ball.
I use simple math to layout the lines to turn away.
This is a very accurate method to use. I used this method for years to round the corners on wood patterns I made for foundry use.
It is a very accurate way to do it plus you are actually turning it yourself and not using a jig to do it.
Plus Wood turning a ball is great practice.
The ball is made from Redwood.

Wood turning a wood ball or sphere
you made that math easy to understand and I really appreciate that! So talented a turner and teacher! BRAVO!
Thank you very much Anthony . I appreciate you watching and commenting.

I wanted to let you know that ever since I got my lathe 6 or 7 years ago I wanted to turn a sphere. I couldn’t afford to buy those expensive jigs that some RUclips turners use. But your video broke it down to its basic elements that I have been turning them for about a month now and am always amazed how great they look. I am even more amazed that I was able to do it! Thank you very very much!
Thanks so much Erik for letting me know of your sucess. I was sure hoping people would try this. I like the method just because I like the math. Plus it is more rewarding to do it this way rahter than use a jig.
Thanks for watching,
Gary
Excellent
Wonderful demonstration
Thanks 😊
Thank you very much Ahsan and thanks for watching.
Gary
Fantastic work I have learnt a lot I'm going to try it
Thanks Brett. Give it a try. You will find it is not hard to do.
Gary
Wowza! That turned into a beautiful art piece! So perfect and simplistically elegant! Fantastic job. Bravo!
Thank you very much Mary!
Lovely work. I turned some balls freehand on request of a friend recently and they wound up looking like the earth - longer diameter at equator than between the poles. But they fulfilled the purpose. Pity I had not seen your great tutorial beforehand. Very informative as usual. Greetings from Ireland.
Thank you very much. I find it a lot of fun to do. And it helps in accuracy if needed. I think I mention in the video I used this technique at work for rounding corners on patterns with a spoke shave. Very same idea.
Thanks for watching,
Gary
Just found your video. Great explanation. Thankyou
Thank you very much, happy you liked it.
Gary
Sure understand not wanting to be a bad influence...thank you on your having a ball video...
Inspiring...thank you...
Thank you very much!
Love that you can use math to create a great work of art. This is my next project
Fantastic Denise and best of luck. I learned that method as a wood pattern maker. Came in very handy.
Thanks for watching,
Gary
Not for me I don't see any applications I could use , however I can see that you know your craft and you are a master of turning , so please don't think I don't appreciate the quality of your work I am definitely going to subscribe because I know you can teach and give me great ideas I look forward to watching more of your work .
Thanks so much Brette. For sure this is not for everyone. I enjoy it because I use techniques that I used at work to create this. But I understand.
Happy you became a subscriber and I have many things to look at and hope you find some of them interesting.
Take care,
Gary
Hard? Only as hard as the wood.
Great video...you probably made Ernie Connover smile...kudos...
Thank you Robert. Interesting you mentioned Conover lathes. I served my pattern makers apprenticeship using a large wooden bed lathe that was built before Ernie was born. In those days a pattern maker would make the pattern for the iron castings and then build the lathe using large timbers. The one I used was made from 4X12's for the rails as I recall.
I also learned that rounding method as a pattern maker. It worked very well for lots of things.
Not sure if you were referring to him making a sphere as I have not seen that.
Thanks for watching,
Gary
Thanks for sharing this method. I turned my first sphere today 👍
Thank you Martin. Happy you were able to make a sphere.
Gary
Awesom! Thank you! I will try this.
Thank you and yes you should give it a try.
Thanks for watching,
Gary
@@ThePapa1947 This method was awesome. Even I made a sphere for first time. I have a foto of it in my instagran account. Thanks again.
@@Lazywatchsmith Thank you, I do not use Instagram but you can send the photos to mgdpapa@gmail.com if you like.
Gary
very nice work . i haven't seen to many people do a sphere with out a jig . well done .
Thank you very much. And it really is not all that hard.
Thanks for watching.
Gary
I have seen a number of videos covering the same operation, but yours is about the clearest explanation. Great job.
Thank you David very much. I have seen a few videos and I just wanted to add a few missing steps that really make it easy.
And actually by having an accurate template the ball is round without the cup centers. Those are needed to remove the nub. Or if you cut to far then you can bring it back into round by rotating in the cup centers.
Thanks again,
Gary
My thoughts too.
No wonder Phil calls you professor….Great work Gary i will try your method , thank you for sharing
Yiannis (Athens Greece)
Thanks so much Yiannis! Yes for sure give it a try. I learned that method of making something round at work as a wood pattern maker. Comes in hand for this for sure.
Thanks for watching,
Gary
Thank you for passing on your knowledge and skill from years of experience. This video was fascinating, clear, and helpful.
Glad it was helpful! and thanks for watching,
Gary
Excellent study of making a ball. East to follow and very informative. You did a wonderful job!!
Thank you very much Phil. Happy you enjoyed the video and thanks for watching.
Gary
Great educational video. Going to give it a try this afternoon. Thanks.
George
Thanks George let me know how it goes.
Gary
Well, you set the hook...I'm a follower. Thanks for the responses. I too have used patterns extensively in finish work on homes and all the way to stringed instrument building. I'd bet you have more old patterns laying around than I but they are great to keep in the files for future reference.
Yes I end up keeping most things. Lots of fixtures and templates.
I've wanted to do a ball for ages, I'll try your method! Thanks for sharing Gary, perfectly explained!
Thank you Matt. I use it all the time. Most recent was the clock challenge that Huw put out.
Take care,
Gary
Great explanation and thanks for the maths lesson. I'ms going to give this method a go
Great and have fun making it. Should be easy enough.
Thank you. My hearing is volatile and hence a challenge for me and am usually deaf with mechanical sources such as you tube. Your drawings and style of presentation along with added texts are extremely helpful to me. When I turn I am very visually oriented and listen to my turning by feel. You sir are a Master Instructor. Thank you again. I could purchase a jig to turn spheres; however, I choose not to. I gain much satisfaction at my age from learning new skills. Your process is not knew; however, your method of instruction is clear, simple and as an ol dog, I finally understand it. I love it when the light comes on. 😎🤟
Gaylan all I can say is thank you so much. The reason I made this video was to show that making a ball is very possible to do with standard tools. And more fun! Strange but making a ball can be broken down to turning a lot of flat surfaces.
You are the reason Sir why I made the video. I wanted to break it down step by step and not leave anything to have to guess at. I hope you let me know how it goes for you. I bet you will have success.
Thank again,
Gary
Gary wow another fantastic and very interesting project. So much to remember, it is awesome.
Thank you Kobie I wasn't sure how well it would be excepted. So far very well.
Thanks for your support.
Gary
Great explanation 👍
Thank you very much Mark I appreciate your comment.
Gary
Very cool math. And a great method to turn a sphere. Thank you for sharing your experience
Thank you very much.
Well explained and very informative. Great video thanks 👍👍👍👍👍
Thank you very much Rex I am glad you liked it and it was understandable.
Thanks for watching.
Gary
Gary, Great job of explaining the way and why’s. Love the tornado ball. 👍🇺🇸
Thank you so much. I know there is a lot of interest in turning a ball or sphere if you prefer. I thought it was about time I did a more detailed explanation. And I assure with all these steps you can get a perfect ball. And the best part its lots of fun.
I like the tornado one myself and have another idea for something on that line. If I have enough left overs from the next glue up I do I might make it.
I am really you like how I explained it. That means a lot to me.
Thanks again,
Gary
Splendid job, Gary. Very well explained. Coincidentally I have been planning to do a video of turning a sphere but using a jig. Of course just because I plan to do it doesn't guarantee I will ever actually get to it! 😁😁😁
Thank you Gord and I would love to see you do one with a jig. I do not own a jig but I actually have been thinking of doing one on my CNC. I use the 4th axis I made for doing carvings but a ball would be interesting to do. No guarantee that will happen soon.
Working on another glued up job. But at least while the glue drys I am turning other things.
Gary
that's very good I'm not very good with math however but seeing you do that without a jig is amazing thanks Gary
Larry thank you very much. I appreciate you watching and commenting.
Gary
Hi Gary, you're a marvel mate ! impeccably explained that even an old boy like me who came into this hobby late in life can follow.
Another great video under your belt mate. cheers , Bram
Thank you so much Bram I appreciate you letting me know it was understandable.
Thank you again for commenting.

Your video was just what I needed, thanks! Yesterday and today I turned 4 spheres of increasing sizes (and made some cup chucks). By using your method they are all pretty darn round. Much more consistent than the one I did "by eye". I didn't need to buy any new jigs or make a template for each different size...just had to remember .414 and .26. I appreciate you sharing your wisdom!
Well thank you Karl I am so happy to hear it worked out for you. I have used that method for years. Mostly for rounding large corners on wood patterns but it is the same thing.
Happy sphere turning to you.
Gary
Hello from Holland. My name is Jan. I was suprised to see you making a bal with only some lines with calculations. These video,s you make is an PLUS for us as hobby woodworkers. Many , many thanks for this explanation and sharing your knowledge in this matter. One question I have. You marked the last edges with a 5” round pice of wood on with you have made some dark so you can see the little differents that scraped away. Now, what dark did you put on these pieces? Greetings Jan 🌷🌷🌷
Thank you very much Jan. I like the math in these pieces and use it a lot.
The black I used is a black crayon. Used for marking lumber. I used it at work to mark templates on many wood turnings. Such as patterns for pump and valve cases. We had red as well but the black seems softer and worked better for me.
Thanks for watching,
Gary
Great sphere love the math it really makes turning a sphere a breeze
Thank you Ron. It makes math fun for sure.
Gary
Perfect! I've been watching several different people turning spheres to learn the different ways, and this one by far made more sense and seems so much easier than the others (no criticism to the other turners intended) I'm already excited for tomorrow to get in my workshop and try this method! Thank you for sharing and explaining it so well! Chris
Thank you very much Chris. I like this method because I think I explained in the video it is a process I used at work where the dimensions needed to be exact. I did this a few years ago but I am sure I did talk about that.
Thanks for watching and commenting.
Gary
@@ThePapa1947 Hi Gary. Being in the engineering trade, using exact dimensions and attention to detail is something I like to do. I've been in my workshop and found an old piece of lime I've had laying around for some time, and I attempted a sphere using your method, and I'm very pleased to say it turned out damn near perfect! I'm very pleased with it. The only issue I had was making the cup chucks adequate enough. But I just need to mess around with them a bit to get them right. So thank you again for posting this, it was a great help :)
Subbed immediately. Love your calm demeanor. Well done.
I understand that the billiard ball turners of yore would turn a shallow, narrow channel on the centre line (your pencil line) of the cylinder before rotating through 90⁰. They would then reduce all the high spots down to this perfect circle.
BTW, the music you played is the best on YT.
Thank you so much for the sub and your comments. Sounds to me like the billiard ball turners had some great tricks. They sure would have had lots of practice perfecting it.
Happy you liked the music it is soothing on your ears. I work best to The 'Sound of Silence. When I first started I had a few videos with back ground music and realized it just did not work for me.
Thanks for watching,
Gary
Fantastic demonstration! Thank you so much!
Well thank you very much. I appreciate your comment and thanks for watching.
Gary
Excellent job. I'm just having a difficult time trying to figure out how to make a jig for my tailstock, that won't take much time. Your explanation was great, and I understand how to make the sphere, and i understand that you have to have the jig for your headstock, and tailstock to make it round. I'm just still trying to figure a way to make a jig for my tailstock, as I usually use a cone center on my tailstock, and I understand that I can't use that because it's too pointy and will indent the sphere.
You could turn a cone and let the tail live center hold it in place.
Hi Gary,
Great project and you explained it very well!
Now knowing that you were a paternmaker explains a lot!
I worked in a factory that had a foundry and pattern shop.I loved to watch the patternmakers create the patterns for the castings!You guys can do magic with wood!
Thanks for thew video!
Tom
Thank you Tom and it is great talking with someone who even knows what a patternmaker is. Not sure how many times I said. "No I don't make dresses"
Thanks again Tom I really appreciate you watching.
Gary
Very nice. I will have to hone up on my math!
Thank you Joseph it does come in handy. It also works great for dividing up a chocolate cream pie LOL
Thanks again,
Gary
Just what i'm looking for TYVM!
Thank you Steven I hope it helps. I know it is a fun way to do it.
Take care,
Gary
Nice video Gary. I really like the segmented ball.
Thank you Don...it was fun to do
Awesome it's looking beautiful.
Thank you very much.
Gary
You are a marvel, Gary! I used to be really good with numbers but with age, I just don't have it anymore. You apparently eat carrots or cauliflower or whatever it is that keeps the brain cells alive! LOL! You explained the process very well and I could see exactly what the outcome would be using your great diagram. Another great video from my friend in Oregon! Keep'em coming!
Phil
Thank you so much Phil! Not sure if I eat enough carrots or cauliflower but I like them a little.
I was hoping it was ice cream or Cheetos but probably not.But at my age I need to challenge myself now and then so I don't forget.
I am doing another glue up that is becoming a bit involved but I think it will be worth it. Keeping me on my toes though.
Thanks again buddy from sunny Oregon, well at the moment it is sunny. You know how that goes here on the PNW,
Gary
excellant tutorial - thanks for sharing.

Awesome. You have a new subscriber. Will use this to show the kids that math can be fun.
Thank you Jim and that is a great idea.I think we use math almost everyday but just do not think about it. This will remind you though when make this.

Hi Gary, loved the video. The tornado ball looks fantastic.
Thank you Simon. I will make another tornado ball but this time make a video doing it.
Thanks for watching.
Gary
Super cool loved the segment one
Thank you. I made the segmented one before I made any videos.
I learnt a lot from you today. Thanks a ton!!
Thank you very much I really appreciate you watching and commenting.
Gary
Nice work and very informative video
I have seen some using a special caliber with 3 calibers connected , a large, medium and small, so the large one is set to ball diameneter and the two other calibers adjust to .414 and .26, now you have all the distances by just measuring the ball diameter.
Using a pipe to scrape as mentioned in another comment, does not require a pipe with the diameter of the ball, a 2" should be fine for larger balls too. I have used a piece of pvc and sandpaper with a slit to make a cone going into opening to sand wood ball with great success. Don't press too hard to avoid PVC melting..
Living in a flat and only having room for a small underpowered wood lathe, it takes forever to turn a ball.
But I have a table saw and a drill so I designed a jig where you can make the ball/sphere in about 5 of minuts.
It's done by turning wood blank by the drill and rotate it around saw blade, a mix of table saw lathe and circle jig
Have a look here for the basics of the jig
ruclips.net/video/egUNaP-0-x0/видео.html
and the one i build enclosing the process to keep fingers away from table saw blade.

Keep safe - Happy Woodworking
Thank you I am happy you liked it. I have been making rounded corners like this for many years. Basically rounding the corners on large wood patterns. It just seem like the way for me to do this.
I could buy or make a jig for doing this but that would not be all that fun for me. Well it would be fun making the jig to do it.
The table saw can do lots of things including making large coves which I have done.
Thanks for watching and all the information on how this can be done.
Gary
Hi Gary, Found you through Phil at Madronawoodworks , who I've been following for a while. They way you explain the process is brilliant and something I will have a go at making. Have subscribed and will look at your other videos. Cheers, Huw
Thank you very much Huw I appreciate it. Phil is really great. He encouraged me when I first started doing videos.
Thanks again.
Gary
Excellent demo. Can you please provide the formula for converting the measurements used to metric? I discovered to work out the cord length in metric, for example, you needed to convert 0 .414 " to mm (10.5) and then subtract that from the diameter measurement (e.g. 56mm) rather than multiple it as you did for the imperial measure. This clarification in your video would save a lot of time for those of us who are not really into maths! Thanks
To convert the imperial dimensions to metric I multiply by 25.4 But that seems to be what you have done.
Maybe I am not understanding your question. But I have been using how I do it for many years.
If you want to email me and show me your method of how you are doing it I would be happy to help the best I can.
You can find my email in my About page. Just put "Sphere formula" in the subject line.
Gary
@@ThePapa1947 Thank you I will do that as although I have worked it out I think I have made that task more complicated then it should be!
When you make your first cut, joining the 2 lines and make a 45 toward the tailstock, when/how did you mark the line on the tailstock end of the cylinder? I understand your math and method. Great video.
When I turned the ends I turned a step down to that size. Then cut the 45 to it.
Hope that helps,
Gary
amazing ! thanks for that !!
Thanks so much I appreciate you watching and commenting,
Gary
Hello Papa! I love your videos. I heard you say you used to be a wood pattern maker, is that correct? Did you make patterns for the airplane/aerospace industry? I have an old friend who is 93 years old who used to be a pattern maker here in San Diego doing just that. He worked for Solar Turbines and Convair after WWII. During the cold war era....
Thank you very much Mark. Made patterns for many things including patterns for Boing turbines.
Even made patterns for the nose piece in front of those engines. It was huge.
Lots of patterns for earth moving equipment as well. Huge drag buckets and the sorts.
As well as some smaller cool patterns for pumps and valves. Parts for large trucks. You name it. If it needed cast we made them. I considered it the wood workers dream job.
All from 2D drawings. I was lucky to retire before CNC took all the work.
Thanks for watching,
Gary
Cool! Done like a true pattern maker. While I find this all interesting, I think I would eye-ball the octagon, then do the rest by eye and the radius profile checker.
Thank you Dave and for sure that can be done. I kind of had to do this when rounding corners on patterns. For some reason they wanted ALL the dimensions to be correct LOL. But after doing a few of these you could easily do them with out the lines and make something nice to look at. Although it may not meet the specs on the drawing but I am retired LOL
Thanks for watching,
Gary
Well done, Gary! They both look good! And your explanation was nicely done ans easy to understand.
Billy
Thank you Billy I appreciate your comments. Glad to hear it was easy to understand.
Gary
Wonderful explanation, going back out to the lathe right now to try it. I'm not sure if this would work, however, if you turn a 3in diam cup and place it on the surface of the sphere, it should touch all around the rim of the cup (if the sphere is true). You could put the crayon on the rim. Thanks again.
Thank you I am glad you liked the explanation. I just make sure I turn the cup so the center does not touch and the rim will set against the surface. Let me know if you have any questions and also let me know how it works out for you.
Thanks for watching.
Gary
Nicely explained and illustrated project Gary. Unfortunately for me since suffering a stroke a while back, my brain can’t process numbers too well, hence I bought myself a jig. The irony is it’s still in the box, never been used !! Nonetheless thanks for sharing, I enjoyed watching very much.
Regards from the U.K.
Geof
Thank you Geof sorry about your stroke. I hope you can still get out in the shop and makes some chips. I think the jig would be a great thing to have and I hope you give it a try.
Not sure it would help but I could probably send a picture that you printed out and you could set you dividers to the lines and not even worry about numbers. But you do have that jig.
Thanks again for watching my friend and take care.
Gary
You must have been a math teacher in a past carnation......enjoyed this video, very interesting. thanks!
Well thank you very much. Actually I was a wood pattern maker which required a lot of geometry and trigonometry. I am lost on algebra though.
Thanks for watching.
Gary
Nice job, I’ve been trying to do this so many times and seems like I’m chasing the sphere down to nothing, just gets smaller and smaller, it was how I mounted it on the lathe but seeing your video now I know how to do it , thanks
Thanks James happy it has helped. Best of luck on your next one.
Gary
That's a neat technique, Gary. I saw you do something similar on the emerging bowl. The engineer in me had to go back and do the math. I recognize the factors such as 0.414 is 1 subtracted from the square root of 2. That's why I always look forward to your next video.
Thank you Bill I appreciate you comment. I know there are lots of online calculators for finding chord lengths. Most are for inscribed circles but here we need the octagon on the outside.
I must say I love math as long as it is geometry I guess that is why I kept my little Machinery hand book.
Thanks again,
Gary
65 years ago, my dad told me that if it's not in Machinery Handbook, you don't really need to know about it. Looks like he was right again.
Ken seems like he might be right. It is a handy little book. Plus I have written down a few formulas that I could not find in the book. Just some things I learned along the way.
One of my favorite things drawing a very large radius just knowing chord length and height and having 2 long straight boards. With that you can draw a section of 300 inch radius and be very accurate. Any size actually, sorry just reminiscing.
Thanks for watching and commenting.
Gary
Top job my friend
Paul thank you very much. Much appreciated.
Gary
Again, great work. You are definitely my kind of turner. Accurate stuff! Just a small suggestion that You're probably aware of. After you've created your 16 sides and removed a good chunk of the high spots, you could use a steel tube large enough in diameter with flat sharp edges as a scraper to finish of the rest. Again, nice work and thank you for sharing your expertise.
Thank you Damiano I appreciate your comments. I have seen where people have used a hole saw that is a bit like you are talking about. And I can see how the steel pipe would work.
Seems like it might be worth trying but then I would have to get the right size pipe. There something about making an accurate shape with the standard lathe tools.
But I do appreciate your suggestion. Like I have said before I like learning and trying something every chance I get.
Thanks again,
Gary
Impressionante a precisão do trabalho. Parabéns.
Thank you very much. Much appreciated.
Gary
Thanks I needed that
Thank you very much. It is a very handy thing to know how to do.
Thanks for watching,
Gary
this may be the best reason ever to explain to my teenagers that yes, math actually is used later in life ..... awesome
Thank you Jimmy and for sure math is very useful for many things. Geometry and Trig is my favorite and what I am best at. Probably because I used it daily for work.
Thanks for watching,
Garu
Math is great. Thanks for sharing. Is the math the same regardless of the diameter? What was the wood and did you mount it in a spindle turning orientation?
Yes for sure math was my favorite second favorite subject in school. Wood shop was my favorite for sure and I went on to use math and wood working in my profession as a wood pattern maker.
So yes the math works on any size diameter.
Take care,
Gary
Wow what an interesting video wish I'd pay more attention in math class.Loved it.learning can be fun and very interesting. Love your channel. I know this is an older video but still a great watch.May you can teach an old dog new tricks.zone mote thing. noticed you wearing a Pittsburg Pirates t shirt. Are you a fan. Not many of them showing themselves this year thanks to Bottom line Nutting(pirate owner). Thanks again for the great video.
Thank you Charles I am very happy you watched this video and commented on it. I always love to see my older videos being watched.
As a kid I was a Pirates fan along with many other teams. I kind of stopped watching a number of years ago.
The pirates shirt was kind of a joke. I play in a small band and we were doing a backyard party for a friend and she wanted the theme to be pirates. The kind that sailed the might sea! I am not much into costumes so our group decided to be a different type of a pirate LOL.
Thanks again for watching,

I enjoyed your ball turning.. I want to try to turn a ball out of a crotch in a tree branch. I have turned a few bowls. Is there anything I need to be aware of with the grains I will encounter?
Hi Nancy, happy you enjoyed it.
If I was going to make one like that I would try and mount it with as much of the long grain you can going parallel to the spindle. That would make getting the basic shape easier. Other than that it should be just fine. I made one out of a Black Locust branch and it cracked real bad on me. I kept it and might get it back in the lathe and sand it up as it did stop cracking.
Best of luck and thanks for watching,
Gary
Thanks for the reply. I'm going for it.
@@nancyjenkins4033 great...let me know how it goes.
I'm a beginner, so excuse the silly question, but is it possible to turn a set of lawn green bowls on a lathe ?
I see no reason why you would not be able to. You would just need to know the shape you want. Probably easier than a round ball.
Thanks for watching,
Gary
Do you have a segment sphere video?
I have this one. Not rings but still segments.
ruclips.net/video/w9WHftQhEZg/видео.htmlsi=SyyEggrfdoAJV5eI
Gary, having turned a few spheres using a template, I have to ask if you are presenting this as just an option or do you think it makes getting to a sphere easier?
From what I have seen setting up the sphere jig takes a bit of messing around. For me I think my methods is just as easy. For others maybe it would not. But what you learn from doing this is very valuable. My method worked great from rounding large corners on patterns where there were not cutters for doing that. And they had to match the drawing. Today they would CNC the whole thing. But when I learned CNC was still a dream.
So my answer is I would not use a jig enough to justify buying one. But knowing me I would make one just for the fun of doing that.
@@ThePapa1947 I would not buy a jig (can definitely imagine you making one) but the cut out templates you used have been enough for me. Still, maybe I'll try this one day.
@@joshblumenthal4873 so you can keep using geometry to add more and more flat spots and you really will not need a template. But I always made them anyway. Some of the piece at work were long and straight with maybe a 6 inch radius. I used very hand planes to dial it in after sawing off what I could. If it was not straight I would use a spoke shave which I always loved using.
Like a lot of things I would just make it and probably use it once. My bandsaw curved segment jig has not been used much lately.
I will as long as I can do something to the turning to make it different. But the jig is perfect for those who like to sell. Which is why I showed it.
Well we have had very hot weather and it is now only 94. You will hear about this in my next few videos.
Stay cool,
gary
@@ThePapa1947 We were in the 90s last week, now just 80s. Take care,
At 5:11, the diameter on the left (viewers side) is roughed in. After the diagramed tutorial, the wood turning resumes @ 7:58, however, the diameter on the left (viewers side) appears to have been tuned precisely. What is the depth to turned it to? 1.035"?
The dimension you are talking about would be 1.46" The 1.035 is put on after the 1.46 is cut. Check the sketch and it should make sense. If not let me know.
Gary
Bonita esfera👍
muchas gracias
Gary
Instead of sweating over all those calculations, it's much easier to simply cut the 5-inch diameter circle out of the plywood and use the arc left as the guide right from the beginning... love the crayon idea!
Yes that would be easier to do especially on a smaller ball which I have done. On something larger it is nice to create a surface you can count on.
I have used the crayon on templates for a very long time. And it is not reserved just for a ball shape. Works great on about any shape you want to get right on.
Thanks for watching and commenting.

When marking out the last two places on each face, shouldn't the cuts be from the end of the 45 degree cut rather than outward from the centre of the spigot?
All the dimensions can be measured from the ends or the center. They will not be the same. If you know the dimension from the ends then you can figure out what it is from the center. Is that what you are asking? If not I will try and explain better.
Thanks for watching.

Thank you How much do you charge for something like that
Thank you and I do not sell but something like this would out of this type of wood I would guess it would be worth $50.00 or so.
Would I use the numbers you mention in the video for a smaller diameter? I’ve been struggling trying to just mark the ends the same as the diameter and then “eyeball” it round. My eyes must be way off. Any help would be greatly appreciated.
Yes those 2 numbers will work with any size you wish to make. The first number used on any diameter will then set you up to use the second number.
Let me know if you have any other questions. I can verify your numbers if you would like.

Im going to give it a try. I’ll let you know how it goes. Thanks
You are very welcome. They are fun to do.
I could have made a jig to cut them but I also could have bought a round wood ball.
To me the fun is doing them freehand.
Best of luck to you.
Gary
"Wow/. I got lucky." 😎
I don't think luck had anything to do with it.
To turn a piece of wood to look like a sphere is not that tough. However, to turn a piece of wood so that it becomes a sphere of a predetermined diameter within close tolerances is a different matter altogether. For that one has to use geometry. In the workshop, geometry rules the day -- every day.
As I said. Luck had nothing to do with it.
Thanks for the video!
Thank you Jerry. My job as a wood pattern maker required this type of math to build what was needed. It is my favorite type of math and I got pretty good at it.
Nice that I can still use it in retirement.
Thanks for watching,
Gary
where do you get the chuck adapter gary
I think I got this one from Ebay. Cheaper than your your local woodworking stores. PSI sells them also.
I prefer using a jig to be more accurate.
For what I use it for it is accurate enough. Curious what you are using them for.
How did you get those octagon plan? Any software Or something for that? I want to make one of these for a while but suck at math
You could search for free 2D cad software.
Or use an online octagon calculator.
Or if you have a protractor that would work.
But those 2 numbers I mention and a calculator just might be the easiest way to do it.
Let me know if you have any questions about any of that.
Gary
I drawed it out and gonna try it out somewhere next week I'll let you know
That's great and please do let me know. Take your time and it will come out good.
Gary
@@ThePapa1947 well it turned out to be a sphere but my calculations were a little bit of. I'll probably try it again soon. Thanks for this great video
@@Guiniss glad it worked out and its a fun project so try again. I would be happy to email you dimensions for any size ball you wish to try. But the thing of it is if your off a little you can still get it round.
Thanks for letting me know.
Gary
what ball diameter in mm?
The ball is 5 inch so it would be 127 mm
Why you're really on the ball. Math is great.
Thank you and I agree that math is great. Especially geometry and trigonometry.
Thanks for watching.
