you mean one mount on the D section of the gearbox and one mount over the motor?

if so then yes. ive done the one end support and it worked less then well.

Ive run a single mounting point on the gearboxes in my old spinner with 9.6v drill motors on 12v and Ive never broken a gearbox in it in 2 years. I believe it allows a bit of flex and movement which takes a lot of stress off the gearbox itself.

Glen has his supported both sides and has broken over 10 gearbox in his life span But plenty of other robots have done the same thing and never broken any ie: KO, Stainless Steel Rat, Mouse Wedge.

Its all up to you basically

In all our kits weve never had a problem. they are mounted over the gearbox. they are also avalible for purchase

anybody got any dimensions of the challenge 18v or 14.4v drills for my cad drawings?

Question:

I cant attach wheels directly to drill motors, but I can attach them to a drill chuck output (the small motors used on the Zeobots have mini gearboxs in them and they seem to do fine).

I take the left hand screw out of the center of the chuck and unscrew the chuck, then thread the wheels directly onto the gearbox of the drill motors. 95% of the aussie bots follow this method.

We found the easiest way was to mill down the chuck and screw it back onto the motor shaft. we then pushed the wheel over the milled chuck and screwed through the wheel into the chuck. We found this to be the most practical solution at the time. I agree this may not be the best way to do it but we found it ok.
Obviously it is heavier than screwing the wheel straight to the motor shaft but as the center of the wheels i had where larger than the motor shaft this seemed to be a good option.

Just a word of warning, if you are looking at using the motors in the zeobots then make sure that axle for the wheel is supported on BOTH sides of the wheel. Otherwise the result will be broken gearboxes every fight!

I have been wondering if i could solder on a crimp spade onto the end of my drill motor tabs

Heres a link of what i mean

Why wouldnt you Alistair? The only thing is you will need to get the appropriate sized crimp. I personally just solder the wire to the tab.

bit of a question regarding drills, for an upcoming beginning class in australia the robots have to be mostly MDF, so im making a horizontal crusher and was wondering -

ive got myself a 12v cheapy drill modified with a piece of m10 threaded rod on the shaft. ive seen a few european robots employ a drill as a crusher so if anyone could provide me with some details as to how much force i could expect from such a drill actuator that would be great (any pictures would be appreciated too)

I tried a similar thing for a lifting arm Glen but used an M8 thread instead of an M10. I was able to lift my bed with it on a direct one-to-one ratio. I dont know what weight my bed was but I was able to achieve a similar effect by using a wiper motor and a length of chain (rack and pinion style) so Im assuming that was roughly 24kg. (might have been more, might have been less). Theres a pic on my profile which I found on the Featherweights.org forum a couple of months back. Its a vertical crusher using a drill and some M8 rod. I dont know the name of the robot or who built it but looks as though it would be fairly effective so there may be a fair amount of force attainable for a horizontal crusher.

hiya lenny, the name of the robot is Loisteputki and it was built by me, the crusher had 120kg of force.. over that force-- one more burnt drill, so it was not a good solution. unfortunately i have lost a pic of it, ill see later on if i find one..

Hey I tend to archive robot combat pictures off of the net I estimate about at least 2,000 and a quick search found a few of Loisteputki.....
