O.K,

Been on the forum for about to weeks now. Thought Id post up an overview of what I am planning to build. I have been researching since december 07 but Im still a bit rickety with some concepts.

Name yet to be decided

Motors: There have been recomendations to use cordless drills - are there any I can find cheap, and will I need two (with chain drive) for a fast rammer/lifter or four?

Batteries: Overlander, Sanyo 2100 12v C NiCads. Its 595grams and provides a max discharge rate of 40 amps. It is 217 x 46 x 23 mm. Taking into account width and weight restrictions how many will a need with a) Four motors and a simple actuator (with a built in battery pack but Im going to overvolt it) and b) Two motors and a simple actuator.

Speedo: Scorpion XXL, or Sabretooth 25A. Will I be able to control the motors and an actuator with a single controller?

Actuator: A slow, cheap Chain actuator, just bolted to a hinged piece of metal. Probably TopMan services, or maybe a vent engineering one overvolted from 24v to 36v by an extra battery pack - is this last specification sound? It will be the built in battery pack, probably alkaline, overvolted by nicads or will I have to change it?

I am hoping the finished design wont look too much like wedge of doom, but that is what Im basing it on - albeit a rather primitive version.

Thanks,

Alex R
