Just an idea, building a robot with no welding

[typhoon_driver]

lidl or aldi will do you a stick welder for 30 to 40 quid that will handle up to around 6mm steel or hardox comfortably. Yes it's possible to make a machine without welding but it's such a pain in the arse and are more limited on the shapes and design that it becomes a right pain.

Also I'm assuming your spinner would be covered up before opening up to stop it being rushed. It's a nice idea but if your reveal mechanism gets damaged then your machine is protecting your opponents. Something to consider.

Also 80kg? Throw that weight into the disc and spinner mechanism!

It does involve a protected spinner but using a mechanism which has a fail state of open. Essentially once it is set at the start of a battle if it loses power, either due to damage or being manually disabled, the mechanics of the system result in it immediately being in the open position leaving the weapon accesable.

As for the weight (which is actually around 90kg, I made a typo in the original post), the numbers behind the system already give it as much power at the tip of the blade as Carbide had in the previous series.

The energy of the impact is nowhere near as important as the spinup time. If it takes 20s to get up to speed it is not going to be very good.

Sounds like your armor isn't very thick, or is made from something very light. On our spinner we have 10mm hardox 500 and 15mm aluminium.

Also our design is almost all bolted. The only welds are to attach the teeth to the spinning ring.

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.

Also for those saying "just buy a stick welder", the reason I'm looking at approaching it this way isn't because of a lack of kit or a lack of experience. I have the kit accessible already and I have plenty of experience, I just find this kind of approach more interesting and at the end of the day I'm looking at building this bugger because it interests me.
