Beautiful man, thank you for sharing, I'm about to embark on my largest sphere yet, and I could use all the advice I can get :) I love the base especially, don't mind if I do say so that I'll be taking that idea right up and use it if my sphere won't blow up on me as I plan to hollow it out completely. Thank you for sharing Sam!
I was born in Akron, grew up in Summit Co. Went to Green High. Then went to play B-Ball in Montana and stayed. I taught school and retired 6 years ago. Where did you grow up? Sam
This is so cool, I am starting to get into turning, my question is, "How do I know which woods can be glued together?" I wouldn't think that a soft wood would mate with a hard wood, but what is the rule on this? I got a bunch of scraps like Purple heart, Lace wood, Maple, walnut...etc. Thank you for any information and I'm excited to watch all of your videos! David
+David Wright Good question I would consider more the issue of density. Some soft woods are fairly hard and are fine to glue up.Some "hard" woods are very soft. I would not worry to much about which woods will glue up better. I think the issue is when you turn a glued up piece, the surface may turn differently with a wide variety of woods with different densities. Sam

I know this is an old post, and maybe you've figured other ways of doing the spheres, but your approach is not quite right mathematicaly, and therefore your initial sphere's shape is quite rectangular @11:38. @4:18 you are dividing the cylinder in 4 equal parts to make an octagon. Mathematically that octagon cannot hold a circle of the sphere. The proper division is - 0.414xD in the middle, and on each side 0.293xD. All summed equals to a 1D horizontally, as it is vertically. This way, when you start making the curves, the initial sphere shape is more rounded, and very close to it's ideal shape. The following is only for the ones who want to hear about the math behind those numbers (I hope I will be able to explain it properly): Each regular octagon is made out of 8 triangles that have angle towards the center of the octagon equal to 45 degrees, and base side that is laying down on the perimeter of the octagon. To find the base side of that triangle, split it in two 90 degree triangles with 22.5 degree angle towards the center of the octagon. The adjacent side is the radius of the cylinder, the opposing side is half of the side we are trying to calculate. tan(22.5) = opposing/adjacent sides, or tan(22.5)=a/r. tan(22.5) = 0.414 we are trying to get the base which is twice the opposing side, so we can double the fraction elements 0.414 = 2a/2r =2a/D, where 2a = 0.414xD (middle part of the cylinder) 1D - 2a = 0.586xD (the left and right from the middle part, which we need to divide in two equal parts). 0.586x D/2 = 0.293xD So, for one inch ball, put a line on the starting point on your cylinder, and them make another line 0.293" away from it, another line 0.414" away from the second one, and make the last line 0.293" away from the third line. find the middle between the first and the fourth one and that is your center line. Apologies for the long post, but I was bored this morning and had some time to spend writing this. If it helps someone, the mission is success, :-)
Paginate Engineer I assume? It is an amazing thing (and I am being serious here) that in 1972 I received a teaching degree and in 1985 I received a Master degree in Education. My math requirements for my undergraduate degree were extremely minimal. I am not good in math-(said captain Obvious)!!! I have done a couple of sphere videos using this technique and I do realize there is something wrong with my approach-mathematically. I will go back and re-read your comment and try to understand your description. However, further down in the comment, I am truly floundering; my left brain is about to explode. (I am a better poet than mathematician). I am not going for the perfect sphere. If I needed to do that I would get one of those fancy sphere jigs. It is really fun to turn spheres and that is my goal. Would you have a link to a video showing this? Or perhaps draw me a simple picture-take a photo of it and e-mail it to me. at samandcheryle@gmail.com Again I do respect and appreciate your expertise on this. I know that when I post a video many people see the flaws or take what I am doing a little more seriously than I do. Thanks and be safe. Sam
Sam, your excellent video shows very clearly how you turn your spheres. Thanks for sharing.
A really useful tutorial Sam, and very well explained. Beautiful sphere as well, at the end :)
Take care
Mike
+Mike Waldt Thanks Mike. I have seen some of your current work on FB----Brilliant, you are becoming a master
Sam
Wow! That’s so cool! Very impressive.
Very nice sphere Sam and good tips

Wonderfull, Sam!

This is truly inspiring. Thank you
Just goes to show what a well rounded turner you are!
Absolutely beautiful sphere!
I realize Im kinda randomly asking but does anyone know of a good site to watch newly released series online ?
@Kylo Donald I watch on Flixzone. Just google for it :)

+Yuval Lahav Good luck. Spheres are just cool to turn....Sam
Nice job Sam. I'm not about to try that yet. I'm still working on pens :-) JimE
Beautiful. Using this principal you could make a model of Jupiter.
Excellent work Sam, nice touch with the base

Is there some where to find out more about connecting the lines and in what order?
Well done sir. Well done
excellent... great job...
cheers...
Beautiful!!!
Professionista, bravo maestro
+Domenico Pugliese Thank you very much.

Thanks for the video. The sphere looks great.
Was the spray bottle to see the grain just filled with water?

+Wood Frontier Yes

Akron Zips? That real close to me. Did you go to collage their?

One day i'll try a sphere...
+Willem Kossen It is easy. Just go about turning a sphere and if it looks a bit odd, just turn it into an egg. (I have done this).

Hola señor Sam con que da el acabado a la bola
Gracias, I used an oil finish---acabado?
GOOD
I know this is an old post, and maybe you've figured other ways of doing the spheres, but your approach is not quite right mathematicaly, and therefore your initial sphere's shape is quite rectangular @11:38.
@4:18 you are dividing the cylinder in 4 equal parts to make an octagon. Mathematically that octagon cannot hold a circle of the sphere. The proper division is - 0.414xD in the middle, and on each side 0.293xD. All summed equals to a 1D horizontally, as it is vertically. This way, when you start making the curves, the initial sphere shape is more rounded, and very close to it's ideal shape.
The following is only for the ones who want to hear about the math behind those numbers (I hope I will be able to explain it properly):
Each regular octagon is made out of 8 triangles that have angle towards the center of the octagon equal to 45 degrees, and base side that is laying down on the perimeter of the octagon. To find the base side of that triangle, split it in two 90 degree triangles with 22.5 degree angle towards the center of the octagon. The adjacent side is the radius of the cylinder, the opposing side is half of the side we are trying to calculate.
tan(22.5) = opposing/adjacent sides, or
tan(22.5)=a/r.
tan(22.5) = 0.414
we are trying to get the base which is twice the opposing side, so we can double the fraction elements
0.414 = 2a/2r =2a/D, where
2a = 0.414xD (middle part of the cylinder)
1D - 2a = 0.586xD (the left and right from the middle part, which we need to divide in two equal parts).
0.586x D/2 = 0.293xD
So, for one inch ball, put a line on the starting point on your cylinder, and them make another line 0.293" away from it, another line 0.414" away from the second one, and make the last line 0.293" away from the third line. find the middle between the first and the fourth one and that is your center line.
