Hi all,
As many of you probably already know I've been planning this for a couple of months and have now decided to stop procrastinating, pull my finger out and get it started.
Wraith is basically going to be a pretty low tech, old school brushed spinner that I can use for Whiteboards and demo's. The idea is to show people that you can still build an effective spinner on a budget, whilst it won't be all that damaging it should throw things around quite nicely.
So without further boring you with words, here's a picture of the main spinner set up, at least the pile of bits that will become the spinner set up, (Haribo's not a robot part).
That's a Johnson 850 motor on a 2.5 : 1 reduction via angle grinder gears wired to a relay and microswitch (still waiting on a servo), a 25mm shaft with needle rollers and a t5 timing pulley (64 tooth I think), a 2kg, 6mm thick steel disc and 2 blocks of 20mm hdpe (250 x 250mm).
Building shall commence soon so look forward to many updates.

It's 8mm thick and 65mm wide, you can see where it will be cut to make the teeth, each one will be 75mm long but only the last 15mm or so will stick out, all bolted together with 4 high tensile 12.9 m8 bolts for each tooth.
I build everything with M8 bolts and then all I need to take with me is a screw driver and 2 x 13mm spanners lol. I don't even own any other spanner sizes than that how sad am I.
