GG's Been a long time since I came out from under the porch, but I need some wisdom from the the porch. I need to make a round sanding device. About 2" -3" in diameter to sand the inside of a sphere. So I am thinking of finding a material to add a grit to, that will break down as using, to continually expose new sanding grit to sand a spherical inside shape. What say the group?

Maybe a better way to ask this question to the groupwould be... How would a craftsman of old make a tool to cut an inside of a sphere? Sent via the Samsung Galaxy Note10+, an AT&T 5G Evolution capable smartphone Get Outlook for Android ( https://akams/AAb9ysg ) |

What material is the sphere made of? Do you need multiple grits? How will you get inside the sphere? What about a piece of syrofoam with grit glued to it? Ed Minch |

Given what you wish to accomplish, the technique of TUMBLING comes to mind. In your case, the inside of the vessel is the final product, but methods are methods. If you look towards jewelry making or polishing of small parts, the methods and sanding materials are all explained. The product that does the work is usually something akin to ball bearings. Put them inside the orb with a polishing product and tumble for days. Frank |

I live in the center of Shaker country, northern Columbia County, New York and eagerly read what I can about Shaker craft. I recall reading memoirs of an elderly Shaker gentlemen who, having served as a journeyman (in the literal sense) at a number of Shaker colonies, had returned to Mt Lebanon and was setting up a shop for himself. He obtained some lumber from a nearby sawmill (probably Shaker) for his bench then walked to Albany to buy some planes (25 miles or so each way, sleeping rough). When he returned to Mt. Lebanon, he gathered some glass bottles, smashed them, ground the powder to make it finer, then glued the powder to paper to make his working abrasive (an early sandpaper). Bottles still being available, I've been tempted myself. -- Graybeard |

Patiently waiting for the other shoe to drop. Why is it we need to work on the inside of a sphere? What sphere? What element is it made of, and why? How big is it? How big of an entry hole is allowed? Or can it simply be turned in 1/2's and put together? If you can open it up, then a scraper ground out for the occasion and used on the lathe is going to be fastest. yours scott -- ******************************* Scott Grandstaff Box 409 Happy Camp, Ca 96039 scottg@s... http://www.snowcrest.net/kitty/sgrandstaff/ http://www.snowcrest.net/kitty/hpages/index.html |

Could this be for a mancala board?https://www.smithsonianstore.com/product /african-stone-game-68558.do?code=N2ISGPLA&gclid=Cj0KCQjwvr6EBhDOARIsAPpqUPHdP_n pf8XSr8dTwVJoGh5Ql6emUWsKgimR5xqO3IA6M75pt0aKa70aAqS1EALw_wcB&gclsrc=aw.dsLoose sanding grits are easily available on the interweb. If it is critical to make a sanding device to sand a half sphere, my initial though is to glue up some thick leather around a spindle, and shape the leather to fit in the half sphere. As long as the width and profile are correct, then the thickness could be less than the diameter of the sphere. Charge the edge if the leather sander with some loose grit and maybe some.wax to help hold it in place, and Bob might be your uncle. Or maybe not. I have never actually tried anything like this myself, so my initial thought could be way off base (totally wrong Jeff).David SobelSent from my Galaxy -------- Original message --------From: scottg |

Great Ideas GGs, The material I am cutting is wood, mostly hard wood. i will be making a lot of holes. If i coated a ball, it would have to be somewhat rigid, some flexing could be tolerated..Thanks all.
