YellowMarble Posted May 9, 2016 Report Share Posted May 9, 2016 When the balls has too much velocity, you must add a fence or rim along the edge of the bowl to avoid balls fly off. Link to comment Share on other sites More sharing options...

That might be a good solution. I'll have to mock up the finished article before it goes into the box. Link to comment Share on other sites More sharing options...

Please keep in mind that the glass marbles have tolerances in diameter and maybe you need to sort the bigger ones out or widen the hole a little bit.

YellowMarble Posted May 13, 2016 Report Share Posted May 13, 2016 The best way is to make the hole slightly larger than the ball diameter to prevent jamming. Link to comment Share on other sites More sharing options...

Some very bad people have certainly led me astray My wife has also decided that we're joining the town's open gardens scheme this year, but that the garden needs some work... I've done a little bit more, but it's pretty much on hold (not abandoned) for a few weeks. Link to comment Share on other sites More sharing options...
