Ooh! I ground the hole in the center of the cake stand top. Started out drilling, then grinding, then grinding some more, but with my technique of holding the rotary tool between my knees(and I'll prolly get loads of comments saying how dangerous that is, but it's the only way I can keep the acrylic steady and move it at the same time(the rotary tool's too big and heavy/unweildy to move around the acrylic properly). I sort of use it as a bench grinder.
Slapped a rubber gasket around a bearing, and stuck it in the hole. A nearly perfect fit(it's not shifting, but still, I'd feel better if it was snug, so I'm gonna use some silicone to make a super tight but somewhat flexible fit).
As of right now, if you type: spinning on a dime in the google search, well, take a look! Right now this blog is the 2nd link!
Ooh, I found a tutorial for cutting heart shapes in wood, using just a drill and some round sanding drums(and no that's not what they're called but u get the idea). So if I need to adjust weight/balance on this thing by drilling holes, I'm going for a heart. It'll be my signature. Like the hole in the Louet wheels, but my very own:).
Holy crap! I think I might be one of those savantes. Without even trying too hard, I originally bought a bearing which is placed vertically in a garage door. Then I proceeded to rollerblade/inline skate bearings. They're also vertical bearings. Just think, I could be out 5 more dollars if I hadn't gone vertical without meaning to.
If I can get my grubby mitts on some mini-routing bits and plywood, I'm gonna make a wooden wheel using what I've learned about felloes. Normally plywood might warp. But with felloes and dowels/turned pieces of wood, or braces, it will remain strong and stable. Nicely balanced too:). Ooh and for a 14 inch wheel one would only need to print their pattern out onto a regular letter sized sheet of paper(think I mentioned that b4). You can get all 4 felloes + some extra parts from about a 14" x 15" sheet of plywood. That means a nice clean piece of scrap, would make an amazing drive wheel.
