Hey guys i went through all the threads about homemade spinners and decided to make one myself.
After trial and error i made one using a vertical mounted bench grinder (Pictures below), but i'm having a few problems and i would very much appreciate it if someone who made one (or not) can help me.
First - and most important i think - is that i'm having trouble finding the exact center of the bowl. I already wasted 2 bowls (Thank God they were cheap :)) and while it may seem fine at high speed and with no ball, once i load the ball it starts moving around *a lot*
I'm also under the impression that the bowl i'm using is not rigid enough (especially the bottom). I had an idea to reinforce the bottom of the bowl with a round piece of metal (possibly the bottom of another bowl or so) but i wanted to ask you guys first.
I will probably shield everything before using it because of water and i will also add a dimmer switch.
Any help would be appreciated
