Riot shields?

I’m looking for a convex or concave former for building a concave round shield. In the past I’ve seen round convex riot shields around and I was wondering if anyone had one I could borrow for a few days. Failing that, one of those round plastic boards that people use for dragging behind boats would be perfect :slight_smile:

A few tyres roped together, with cardboard across the top to smooth the surface? (Says me, the armchair ghetto-fixer, so any suggestions on my part are largely speculative/improvisational)

I was looking for a large smooth concave or convex bowl shape as opposed to a simple curve. Thanks for the idea though.

This kind of thing:

Oooooh. Right. A hemispheroid. Hmm, certainly trickier to conjure out of thin air.

One of the meerkat viewing domes at the Zoo? I’m just trying to think where I see that shape regularly in daily life …

A large plant pot? Landscaping baubles?

Hang on … at the last Chrono game, I think there was an NPC robot that had a domed head, which was maybe 80cm wide (memory from months ago, so measurement accuracy not guaranteed). Dunno how solid it was, though.

A 4x4 tyre cover might be ok too?

does it have to be solid? because if it doesn’t you could use one of those large inflatable gym balls.
