It would probably be ok to use 15mm but if you go to 20mm i think you can be sure it will be better, i would use 20mm thats all.

Dont forget 10mm is almost "sheet" and 15mm is not far from 10mm, play it safe mate...go for 30mm

like lee said, 15mm will 'do' but if you can go to 20mm then i would, I did with my machine and that is really solid.

Does depend on what you will be making on the machine though as to how solid you actually need it.....
