harry's stupid featherweight questions

Postby haz » Fri May 20, 2011 3:03 pm

hey, for my next featherweight it thought i might build a replica of "private iron" off of spaced, ive got most of the parts worked out in my head but there is one thing that is bugging me, is it posible to make a big ass servo? like get a drill motor and some how atach a potentiometer? this would be for the axe, not desighned to be efective, just move up and down. ive got a load of cheapy esc's which ive modified to take 12v would they be any good?
thanks in advance, harry :D

Entirely possible http://www.teamonslaught.fsnet.co.uk/wiring.htm

You might be able to use a couple of the relays from technobots and a pair of diodes instead of four relays.

http://130.94.182.150/mowers.htm that's something similar and gives an idea on how to connect things mechanically

I just properly read your post, love spaced.

Don't think you'd be allowed to enter most of the other one's though :wink:

6mm is what alot of people use, it does flex very much.

i am curantly using a 1mm stainless steel base and it seems fairly ridged, i still don't think 6mm hpde is stiff enough, maybe 6mm polycarbonate

6mm polycarbonate is much stiffer than 6mm HDPE, so I'd go for that out of the two.

Aluminium is a good alternative. 3-4mm is usually a suitable thickness, although it obviously depends on what is being attached to the base plate, any forces it might have to withstand etc.
I tend to avoid steel for base plates purely because it's harder to work with, and when there are lots of bolt holes and mounting points being drilled into the base, it makes life easier if the material is easier to work with. But that's just my personal preference.
