From The Ground Up (Advice Thread)

i just stick a screwdriver in the end of the motor so it cant move and screw the wheel on.

as for mounts what i do is drill lots of holes so they make a 3 by 2.5cm rectangle then it remove the center and file it untill a drill motor can fit in, then its only a case of using a hole saw on another bit of plastic for the end of the motor to slot in. total cost of about 5 quid.

Cicatrix' motors are entirely supported by the gearbox end as Harry described in the first half of his description then further held in using plates from the drill being screwed in through the plastic from the wheel end.

Aaah! Yes I remember now, there was a video of that setup being built, but I don't have the link?

Thanks again! Got some of the holes drilled and countersunk, one went wrong so we had to use some synthetic metal to fix it, but such is life not being a robot

All finished with the body, total weight is about 7.5kg Gonna take it back to good ol' Lewes to do the wiring, has anyone any advice or know how on modifying NiMh batteries? I have 6 8.4v battery packs and I want to convert them so I have 4 9.2v

[harry hills]

dont short them nope its pretty simple, take cell out, put another in

And wrap it with heatshrink? Or just some good old insulating tape? :wink:

[RogueTwoRobots]

I tend to cover mine in a layer of insulation tape followed by a layer of gaffa tape. None of this heatshrink malarky for me
(although I've seen an Australian roboteer use empty coke bottles melted with a heat gun as a form of heatshrink - pretty cool solution)

[maddox10]

I can garanty the coke bottle shrink wrap option. It works, but pretty?

I plan to do that, lol. Would a decent hair-dryer suffice?
