Metal thicknesses and recommendations for spinner proofing

[plargen]

with that design you could do 20-30mm hdpe sides cut to shape and bolt metal plate to the hdpe at the 3 angles you wanted then if 1 gets damage you could just replace the the 1 section

Useless, the lot of you. None of you came out with it.
Any thickness of material will come off if not secured together securely.

Lol that made me laugh.

Thats a really good idea, would you use angle iron etc to drill and bolt it all together or just literally drill and screw it all together?

[plargen]

either should work but i f i were using 20mm + then i would use something like these screwed into the hdpe

and then bolt through the base plate, lid etc

There OK, but to me, they look very liable to strip the HDPE. I would probably just go for self tappers, they have worked well for use so far.

But the again, I have no experience with them so what do I know !
