Thanks to Tom for providing the PDO,
I have thickened the walls and smoothed the shell where possible.
Do post some pics if you do take it on
Cheers Jace
Just a note the neck hole was quite small so I've enlarged it to 18cms wide to accomidate an adult head. This will have over all increased the helmet size. So you may want to reduce the helmet to your needs and dremel out the bottom to fit your head in : )
