    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.

    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.

    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...

    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.

    Spinning nicer I think. Can't feel or hear the motor over revving so much.

    First up

    https://www.youtube.com/watch?v=h4Mm...ature=youtu.be

    Span the thing. Good points and bad points.

    Bad points:

    -belts got warm (unsurprisingly) so stretched. This is why its flapping around in the video
    -I'm loosing a several thousand RPM somewhere, probably because of belt tension but very annoying all the same. Hope I can fix that.
    -One belt snapped on spin down of the first time. But as the second one was fine throughout all the testing can put it down to dodgy joints.
    -30a ESC hella hot so switched to the HK own brand £7 lumptroller. Heavier but it didn't miss a beat.

    Good points:

    -Nothing exploded
    -It span with no tension and one belt
    -Motor makes noise to scare opponents
    -£7 ESC actually worked.
    -Batteries were not hot to the touch


    Also bearings came for disc. Ended up having to bore out the bore of the hardox disc a little so that the shaft sat nicely through it and didn't add any friction to the setup. TIL rubbish brazed carbide boring bars can touch hardox.



    heers.

    If it looks like it will be a problem I'll change them out.

    That's so awesome! I do wonder if the connectors on the battery packs will take the current draw of the spinner and drive. Might be worth changing.

    Stuff happened.



    Stupid stepped shaft was booped out. Made a silversteel replacement.



    Quickly made up a motor mount plate. Excuse the screws. I didn't have any hex countersunk M3 the right length





    Assembly with the neat little standoffs from Elvis.





    Carbon fiber base, HDPE rear armour.

    Yeah, MT3. We have a chuck and collet system for it.
