I taught id share this idea i made today in approx one hour and very cheaply using left
over wood, silverline drum sanding bits-€10, A halfords power drill -€25, and a bracket to hold
the drill on the bench which i got at a fair for about €10.
This is extremely handy for those awkward
sanding jobs and the silverline kit came with
five different size drums, from 10mm to 50mm and pads of different grits aswell, I got this on ebay.
