Shredder gets stuck

i have been trying to build the shredder, but at the beggining the 5mm sheets where not availabke so i decided to make all the blades on 6mm, after i finished the assemble it doesnt rotate freely beasu of the friction that akes one blade to another, do yo know how can i fix this? i tried to pulished the shredding shaft but it still gets stuck.

@pablosaker1 If you used a different metal thickness, you also had to enlarge the side panels of the shredder because when you add up the thickness all of the rotating knives and spacers, the total length won’t match with the side panels

Hi try to eliminate one blades of 6mm and a ring of 6mm so you will eliminate 12mm and this little bit the thickness of your 13 mm between blades and rings of 6mm , hope that’s work for you
