Legal, Smeagol (as J R R Tolkein would say) 

, I'm only doin' it for my own enjoyment, not trying for anything "official".

Yup, before I added the brush, I had two arrows smash and bruise my forearm 

One exploded... but I had to try again 

... my nerves were shot for days. I tried it today, shoots sweet as a nut, but I had extra strapping on my left arm, safety glasses and a bump cap 

 (true!)
