Substitute 4.5mm thick for 5mm thick in the shredd

My laser cutter just returned my quote, however they do not stock 5mm plate only 4.5.

Can I substitute this?

Also I am looking at using MS plate and case hardening the tips of the blades

Hey @btmetz, I also don’t have access to 5mm stainless and I suppose it is possible to downsize a few parts of the shredder to make it work but I just went with cutting it from MS… I’ve been using my MS shredder for most of this year and its holding up just fine… the plastic doesnt seem to dull the blades at all.

so your 4.5mm parts worked ok?
