Ok

The plastic has arrived today.
little Q,
I want a spiining disk for kilo bot approx 170mm in diameter and want to weigh under 300 grams what thickness should I use and what material (i'm was either going to use Hadrox 450m, P20 or Grade 5 Titanium)

Find the density of the material you want and do the maths to calculate the volumetric size of your bar and you have your weight.

For comparison, the bar on Spinza is 270g, some sort of steel, and 320mm x 45mm x 2mm.

It's far too heavy though, components alone for Spinza weigh a Kilo.
