^^ what Niels said .

That looks fantastic, you've got to show us it in action ASAP!

Looks awesome Harry, we need a smashy smashy video I think

The gnomes are my dads. Spurs home and away kits on the pair. I don't think he'd ever speak to me again if I broke one lmao.

I'll try and find something to break. See if how high I can chuck stuff. Wish I could tach it to find out what speed I'm hitting. Probably still loosing like 3-4k.

Spurs home and away kits on the pair.

I'm such an idiot, it took my 10 minutes of racking my brains and rereading that sentence to finally figure it out...

I'm no football enthousiast, that's for sure.

I actually thought your dad dressed them up as cowboys at some point. Well to each his own...

Hahahah, brilliant

Egg comes in at 1420g without a lid. Weight limit fail. That said the plastic version had hit 1600g without back or lid. I can easily claw that 20g back without heavy machinery. Lid will have to be 2mm carbon fibre unless anyone wants to give me a 67 x 235 bit of 1mm. Still got bits of unpockeded alu oozing weight so I should be able to take what I need out of there. Wheel guards will just be folded HDPE for weight and simplicity.

Been hitting some stuff with it today, trying to find weakness. Found lots lol. It tends to knock some of the bearings loose on big hits, this caused the beater to shift to the left and wreck the end of the bearing pocket. Will fix with a file then have to ignore the ugly as no material/inclination to make another bulkhead. Fixing this is easy it just adds precious weight.

Any imaginative ways to remove weight without doing anything stupid?

Thanks.

Try adding a grub screw or two to pin the bearings in place. If that fails get some of the really strong Loctite and have a blowtorch to hand at events in case you need to release them.

[harry hills]

I don't particularity want to grubscrew onto bearings... it feels very notgood. I'll just add a plate to the bulkhead to stop it getting thrown outwards on the big hits. With stuff like Elvis's new horizontal I think any adhesives would fail.

[Mouldy]

Mk3 put the bearings on the inside face lol

Drill n tap the ends of the beater shaft and put a bolt and washer on to squeeze it all together.. will help stiffen up the chassis at the same time.

And yeah grubscrewing onto a bearing is a pretty nooby idea.

[Mouldy]

Fyi washer OD shouldnt be bigger than the OD of the inner race on the bearing.

Got to be better than nothing at all and having your weapon destroy your own machine. Just giving some options

[harry hills]

Thought so, putting pressure on a running high speed surface didn't feel like it would end well.

Cheers for the input on washers. I'll give that a go for now. Yeah next version I should have 12mm thick bulkheads, 10mm to house the bearings and then the 2mm to stop the stupid problem.

Does anyone know when, and where, will be the next opportunity with an arena to fight beetleweights?

Hey guys
I've confirmed with Alan that I can have the beetle arena at Stevenage, but we may have to pack tight if it's anyone with just a beetle (I think every beetle roboteer has a FW), so get building/repairing .

Hope to see you there if you can make it

[john_frizell]

Thanks for the reply. Unfortunately I'll be out of the UK and so won't be able to attend. Any idea when there will be one after this?
