flying dog Posted December 23, 2013 Share Posted December 23, 2013 About the size of a tennis ball. Needs to be openable and hollow, and resealable. I'm guessing some toys would come in them, but I am not having any luck finding where I could get a couple of them. Link to comment Share on other sites More sharing options...

Thanks. Shall investigate further. Link to comment Share on other sites More sharing options...
Gnarly Gnu Posted December 23, 2013 Share Posted December 23, 2013 What diameter range is acceptable? Link to comment Share on other sites More sharing options...
flying dog Posted December 23, 2013 Author Share Posted December 23, 2013 Gnarly, There is no real specs. Tennis ball size is a good average. I need the "Goldielocks" size: Not too big, not too small. Sort of thing. So from golf ball to ....... 10cm diamater. Tennis ball seemed a good size to mention. But! They need to be hollow, openable - if only once to do the "magic" to them, and not too expensive. Link to comment Share on other sites More sharing options...
old man emu Posted December 23, 2013 Share Posted December 23, 2013 OK. I'll ask the obvious question ... What are you going to do with them? OME Link to comment Share on other sites More sharing options...

Gnarly Gnu Posted December 24, 2013 Share Posted December 24, 2013 Perhaps what you need is a plastic aerial shell (fireworks), they come in two halves that clip together. There would be a small opening on one for the fuse, not sure if that's a problem. Could be welded over. Link to comment Share on other sites More sharing options...
flying dog Posted December 24, 2013 Author Share Posted December 24, 2013 Welded.... So it isn't plastic? No problem, but now I'm interested. What do they cost and where do you get them? Example url to see picture/price. Link to comment Share on other sites More sharing options...
Gnarly Gnu Posted December 24, 2013 Share Posted December 24, 2013 Welded as in plastic welded that is. They are some moderately brittle type of plastic as they are designed to shatter. I just googled and found this picture (the plastic ones are on the right): You only need a couple right? Link to comment Share on other sites More sharing options...
rgmwa Posted December 24, 2013 Share Posted December 24, 2013 I have a recipe for gunpowder and some ideas for a release mechanism if that would be useful. rgmwa Link to comment Share on other sites More sharing options...
flying dog Posted December 26, 2013 Author Share Posted December 26, 2013 Gnarly, Yeah, they look ok. Quickie: What are the ones on the left? Wood? Wood could be glued. So, it is possible for thin WOOD spheres also. (Sorry, but I guess I need to keep an open mind.) Link to comment Share on other sites More sharing options...
Gnarly Gnu Posted December 26, 2013 Share Posted December 26, 2013 The ones on the left are pasted - kinda like paper mache really (French for "chewed paper"). You make these using kraft paper on a hemispherical former. Not as strong. Link to comment Share on other sites More sharing options...

flying dog Posted December 28, 2013 Author Share Posted December 28, 2013 OK, "Next" question: What "Shop" would I go to to get an old ball bearing which has failed? Probably a bearing shop - right? About 5 cm diameter. Why? Well as I now hope I have the sphere I Need, this is the video which inspired me: I'm guessing syrup would work rather than honey.

Gnarly Gnu Posted December 28, 2013 Share Posted December 28, 2013 Haha, neat. Many guys would aspire to own balls of steel (boom tish) but yeah as you suggest head to a bearing shop first & ask what they can do. Link to comment Share on other sites More sharing options...

planedriver Posted December 29, 2013 Share Posted December 29, 2013 Now you've got me thinking about other applications. I once used a hydrualic brake attached to the gear rack on a big automatic sliding gate I supplied, which opened up a steep gradient. The reason for the brake was that in the event of the motor being dis-engaged while in the open position, about 400 kilos of wrought-iron gate would have raced down the slope to the closed position, taking out anything in it's path, with potential lethal consequenses. The hydraulic brake only allowed it to close slowly and 15yrs on still works like a charm. Now i've got to make a magic ball to amuse the grandkids, to go along with my other party tricks. Thanks for the idea. Link to comment Share on other sites More sharing options...
