would these be ok?

[mattsdragons]

i have got some caster wheelsd with no tread too give good grip.

and doing the nut up tight stops the morots from turing

[mattsdragons]

any ideas?

[haz]

hang on a mo dosent tread give more grip? my advce is to get blue wheels from roboochalange

[mattsdragons]

i cant get any grip from the shaft of the motor on the wheel hub

Can you post a picture of how you've got the wheels set up at the moment so we can give a better suggestion on how to put them on

[mattsdragons]

i cant, sorry. but basiclly, the wheel fits over the shaft but i cant really get any grip from the metal shaft on the inside of the wheels

[daliad100]

Is it a close fit because then a large pile of loctite might do the trick if you scuff up the hole a bit for more surface area.

Or you could just buy some blue wheels with a nut insert direct from robochallenge or second hand

or if they are wide i got some copper pipe that was in between the too and cut a slot down the side squashed one end in a vice and hammered it in to the wheels, i then cut it to size and pushed it on to my drill motor then i put a bolt through it.

for an axe you could use pneumatics (i am for a heavy) or you could use an electric motor like pure evil. a motor would be easier (probably).

Team RCC's Kashei uses a Speed 900 as axe-powering motor and a 3 stage reduction gearing with Mod 1 gears.
