I made some myself a while ago, a one off set though. Sold them a few months ago.

I use some 5mm ali for the sides. Had a few brackets front and rear. A 5:1 ratio using 6mm sprockets and chain from technobots with a steel shaft running through some blue wheels.

Very easy to make with a jigsaw, a drill and a bit of time.

Total cost including motors was around £110 for the two. Not too bad for a featherweight.

i think due to the lack of funds (you people have expensive taste) ill go down the 18volt motor route

does anyone know the speed i will get out of these and, do the xbnotz mounts fit 18v aswell as the 12v?

cheers alex

Im not 100% sure on this but, assuming the ratio of the gearbox is the same, then an 18V drill motor on 18V will give the same speed as a 12V drill motor on 12V, (or a 9.6V drill on 9.6V and so on) the only difference being that the 18V motor has more power therefore youll get a greater output torque. (something I am only realising the need for now after running four 9.6V drills and not really being able to push another feather)

This may differ however if the advertised RPM of the 18V drill before it becomes roboticised (i.e. when its still living in happy drill land) is higher than the advertised RPM of a 12V (or other voltage) drill.

Can anyone confirm/clarify what Ive just said - Im not entirely sure of it but I think its right.

And provided the 18V motor doesnt differ too much from the 12V motor in terms of physical size (mainly diameter of motor/gearbox top bit) then it should still fit the Xbotz mounts no problem

Most 18v drills will be the same size as other smaller drills only wound differently. An 18v drill on 18v will have the same power as a 12v drill on 12v or equivalent.

anyone know of some good cheap brands of 18 volt drill? something that can do the job but wont cost the earth

I found my 18v drills in woolworths for £10 each. I am not sure if they still stock them though. I got them about 2 months ago.

just checked their website could only find a hammer drill 12.50 got a link?

also these 18volt drills should make my robot go fast than the bosch 35s, right?

Thats why I am not sure that they sell them anymore. I found them on sale in woolworths in Glasgow. I also found some in the woolworths in St andrews. I dont think they are buying them in anymore though.

I was in woolies the other day , the only ones that they have in were 18v but they were like 19.99

tescos do them for like 4.99

[typhoon_driver]

if i remember correct the tesco ones are only around the 9.6v range.
