Recently started turning small eggs and spheres from scraps from bowl making. I would rather turn them into eggs and spheres (I refuse to call them balls because of the harassment my wife gives me when I tell here i going to go make some balls) to give away to the neighbor kids that inevitably gather when ever the shop doors are open and ask the normal questions of “whatcha doin”. So tonight I wondered How big a sphere I could turn strictly by eye. All I used was a set of calipers to get the lenght equal to the width. I chucked the 9” x 12” block of Redwood Burl into my Nova and used a shallow non penetrating tailstock. Using only a 3/4”bowl gouge (the only tool I’m fairly proficient with) sharpened with long fingernail/Ellsworth/Irish Grind. I roughed in the shape and fined with a shear scrape. Finishing the right side first I cut off the tail stock and sand the nub. I previuosly have turned a cup shaped jam chuck for the Nova Swapping ends and putting a piece of rubber shelf liner between the cup chuck and the sphere, the other end goes on the non-penetrating tailstock and gouged and sheared I power sand everything with a car polisher with velcro backed disks, 150 and 220. when complete I used a sharp chisel to remove the last nub.I chose not to finish the sphere, usually for Redwood I would use Cellulose Sanding Sealer followed by 3 to 5 coats of Lacquer, and polish with Beeswax. Hope this gives inspiration to someone to try their own. The sphere has a magical appeal that everyone that sees it has to run their hands over it. Thanks for following along Best wishes FordMike

wow, that is fantastic! now you need to make an equally impressive pedestal to sit it on. No pressure or anything.

P.S. Nice work. Wish I had pieces of redwood scrap like that lying around. :)

-- I hope the volume of shavings one creates is directly related to the probablility of one's success, cuz if so I've got it made!!

thanks I’m working on a pedestal thats uses a aquarium air pump to float the ball on a cushion of air and you should be able to spin the ball and have it rotate and spin for a very long time running on bearing of air. Thats the hypothenuse anyway. I’ll post pics once it’s all finished. FordMike

Great turning – hard to get right – as are the egg turnings – I know a guys by the name of Don Riggs who could turn these by eye in almost no time at all. He had buckets of them he turned out of all size of scraps. Instead of calipers, he used to check his with different size rings he kept (depending how big a ball he was turning). When you laid the ring on the ball, it was like checking the cord from one side of the circle to the other If the inside circle touched the ball at all points, the ball was almost perfect. He would rechuck it between two cup chucks (that almost makes ya sick) and finish the ball off checking with the ring again. Hope that helps with the sphere work.

If you were a girl, I’d call you a “shperical girl in a spherical world”. Nice job, and nice chunk of wood.
