drive wheel size

WOW - that's humming. At 7k rpm is almost 13k SFPM belt speed. I think that would scare me! Can you imagine a 36 grit belt breaking at that speed while grinding? In the blink of an eye you could get some serious skin rash..... right to the bone!

It is scary if a tyre comes off a wheel though - bounces round the workshop for quite a while.
