Youll have trouble mounting the motor in Doms mod kit without the gearbox attached - after all thats what stops the motor rotating with the torque.

Im going to fit a small polycarb flange to the front mount, thus stopping the motor from moving... (anyone know when the new technobots store is coming?)
In terms of disc mountings, that dosnt sound too bad. the only thing that comes to mind is disc 65mm dia. by 8mm thick in steel weighs only 208g and has a moment of inertia of 0.003876 ft/lb/s^2 before machining. So even if you are going to spin that at 10,000 RPM you are only going to deliver a little over 89j of kinetic energy into your opponent..I seems a hell of a lot of work for very little energy!
Something to think about!

Maybe 20mm steel sounds better...
What, you mean a 20mm thick disc? or a 20mm dia. shaft?
Disc (do you have MSN?)
Im not sure if Dominics drill mounts are suitable if youre only going to attach a single motor.
If Im not mistaken, there should be three small screws in the front of the drill motor.
My suggestion is that you use those screws to attach the motor to the 10 mm aluminum blocks (picture in my profile).
As the pully will be very small, the belt will probably slip every time you activate the disc. A chain would work much better!
In order to get a little more energy out of the disc, I would suggest that you actually exchange the disc for a drum. As you will then be able to increase the weight of the whole thing, and still keep the robot invertable/invertible.
If youre only going to use a single motor, then Id suggest that you overvolt it.
Or Ewan why not just use a gold motor or silver motor.
I think A Sliver motor would be almost perfect. Give a bit more power than just a drill motor

Im using a timing belt so slippage shouldnt be a problem. And Ill look into the aluminium mounts as being part of the motor mount also (thanks for the pic)... Im overvolting a 9.6v motor on 14.4v...
Ive been now thinking of using two 14mm steel discs bolted together, this would be an effective 28mm spinning steel mass. again 65mm diameter... And also milled out in the centre...
Ill release pics of the build soon... (on http://www.micro-maul.co.ukwww.micro-maul.co.uk) Oh and Geoff, When will your website be up?...
A silvers RPM is not anything close to a drill motors. A drill WILL gat a small disc, like the one I plan, Up to speed farely quickly...
