Drills

[nemisis]

im looking for some model monster truck type wheels. anyone have any idea where i might find some. (roughly cd diameter)

model shop?
just a guess.
more importantly though, they will squish (technical term?) under 12kg.
you can fill them with foam, but this gets heavy.
good luck though, it might work...

Electric Brick (Bob Colemans machine) seemes to work perfectly well with them.

really?
interesting....
how high a ground clearance does he have and does he ever get stuck on the floor? also, has he glued them on?

Electric brick had quite a high ground clearance but that is because of the design of the bot. As far as I noticed the tyres never squashed enough for the chassis to touch the floor nevermind get stuck, also he seemed to have a lot of grip on the nice shiny MDF floor at inspire while alot of robots were sliding around all over the place. They worked so well I was thinking of changing the design of my new robot (to be unveiled in aberystwyth) to incorperate them but i was already too far into the build.

I know what the lack of traction is like on a slippery surface, our 12v 340watt winch motors couldnt get the power and torque to the floor due to our mower wheels being to hard in rubber compound

Does anyone know if the 14.4V challenge drill driver avaliable from argos has sealed gearboxes? or do they fall apart like the ones from B&Q?

Also if anyone knows of any drills that do have sealed gearboxes could they post here as a list of suitable (and unsuitable) makes would be useful

Does any one know if teh b&Q 6v one is sealed?

What do you mean by sealed, do you mean the bearings are contained within the case?

When you remove the motor and gearbox from the drill a sealed one will stay in one piece, some (like the B&Q ones) fall apart so need to be fixed together before you can use them
