So after a great time at Manchester (thanks for all the positive reception Road Bump received!), and spending a bit of time talking to Jamie McHarg at the event, I think the time has come where I'm ready to build a spinner.

My plan is to go for a drum spinner, approximately 100mm diameter by 150-200mm width. I have already bought what I feel is a suitable motor: https://hobbyking.com/en_us/turnigy-...___store=en_us

The main area I'm struggling to work out myself is what goes into a suitable mounting system. Basic stuff I could really do with some pointers on:
  • Shaft material and diameter
  • Bearings/bushings
  • Pulley ratios
  • What style of drum is easiest to make for someone with limited resources and connections?


Any help would be hugely appreciated!
