I asked for 2mm plate but he only had 1.5mm in stock mate.
It seems rigid enough though.
I picked up 3 flappy discs a week or 2 ago.and used 1 to take the bulk of rust off the tow bar bracket.before hammerite painting.
I've been looking at sand blasting cabinets.but a decent air compressor is needed to run 1 I think.
Maybe 1 day I will get 1.
