Three questions ...Yes ( but not enough in general to worry about )... Yes and Yes.

Danke Schonne .
Will need that. Merci.

Grazie,

Alex

P.S Corrections on Danke schonn? I think I miss -spelt it.

EDIT: Will this be O.K on the torque front?

That is a corded drill and so works off 240AC not (as you are allowed in the rules) up to 36V DC.

A simple rule. If you plug the drill into the wall, it isnt useful to you. If it has a battery that needs recharging every so often and is in the voltage range of 9.6V to 36V it is useful to you.

O and stay away from hammer drills. Stopping the hammer motion is a bigger hastle than its worth.

Ok. What about these. I know Im just throwing links around but this is a forum.

Thanks for the advice about the plug although the problem probably would have become clear once I had bought it

Ill throw a link back at you ...one that I gave before ...http://www.4qd.co.uk/faq/roadspd.htmlhttp://www.4qd.co.uk/faq/roadspd.html

Put in the cordless drill RPM ...1,200
You will be screwing a wheel on in place of the drill chuck so ...Gear Ratio = 1

Use a wheel dia of 100mm

Output = You tell me Alex R

Id really like you to try and use the calculators.

The above rpm and wheel size is fairly common if your using cordless drills as drive motors.

The reason I was asking for more drill links is because the speed that a 1100 rpm drill gives me with 4 inch wheels is about 13 mph. So I have, in fact, used the calculator, and done everything you have told me to do on the calculator. This is a forum. Im not as experienced as you, but if I was I wouldnt be here.

[aero_storm]

I knew that would be thrown back in my face.

No, thats not what I meant. I do appreciate the help Im getting. I was a bit irked due to the fact that despite trying my best I just wasnt good enough. But, hey, Im not experienced, I have built no robots, so Ill take what comes.

Alex

P.S Back to the topic now?

P.P.S Sorry :blush:

Alex R ...I happily make allowances for newbies ...young or old.

Whilst I could have given you the specs for everything ...I believe its a good idea to at least make you do some homework on the subject.

So homework done.

I think for the price range your looking at ( cheap ) perhaps 4 off 9.6v drills run @ 12v with 100mm wheels giving you approx 8 mph.

Getting the higher 1000 plus rpm will probably require you to double or treble your £ spend.

[aero_storm]

Ok, thanks. My calcs say that if I overvolt a 750rpm motor with 7cm wheels, I get 13mph. This is what I will go for. Then Ill just see what happens.
