Just an idea, building a robot with no welding

[TechAUmNu]

Surely someone has flagged that up as a really bad idea :-P The welds will crack/fracture. If the teeth a keyed in then its not so bad but still... That could be a major safety issue.

They are fully welded on all sides and recessed. Bolts can break too you know. If you are that worried about it, you can attach them with a safety line.

I wouldn't bolt them on either. All our weapons are singe billets of metal.

If we could do them as a single piece we would.

Its fair enough to make a normal bar or disc spinner from a single piece, but ring spinners are exceedingly expensive just for the ring itself. It would be possible to do if your teeth are inline with the ring which for our spinner would be £>1200 for a single piece to get water jetted. However, our teeth are angled at 45°. So either you get a huge slab of hardox and somehow machine that down, god knows how much that would be. Or you get a single piece ring and weld the teeth on.
