last time i had drill issues as in chuck being screwy i simply as andrew said put a large allen key in chuck but the entire drill was still together, i clamped drill in a vice and with a hammer i very suddenly and swiftly hit the allen key, the sudden jerk and force was enough to free the chuck and it unscrewed _________________ Andrew Welch, Team Unconventional Robotics

It sounds like he has removed the clutchsprings and balls ect so the shaft will just be spinning free with nothing to torque against and he probaly doesnt have room to put in grub screws if the bits of clutch housing are still between the chuck and the gear box housing in the way .
Thanks, i have enough room to put in the grub screws but it's REEEEEEEALY difficult _________________ Oh god, that old signature was terrible...

I just put in normal screws that were 5mm across and sawed off the excess. Then I had more screws for the second drill motor. It works perfectly.
NOTE:I HAVE tried this idea. Is it supposed to only move 90 degrees if you turn the shaft really gently? _________________ It seemed like a good idea on paper...

If you left the clutch intact would that make the motor more reliable in a spinning weapon?

It would make it slip, so I guess it would. I believe BudgetBot used a drill with the clutch for its flail weapon. _________________ ( •_•)

Our first Robot No. 5 we had the drill clutch still connected and one problem that did arise was that the clutch had a habbit of moving by itself during operation so that in the end you ended up with a clutch that wouldn't stop slipping.

Drill motors are a terrible choice to drive a weapon - the RPM is too low, the gearbox can't take the shock and the output shaft bends easily. For the same or less cost, you can get a car fan motor that will last and do a far better job. _________________ Australian 2015 Featherweight champion

The clutch on Budget Bot's drill motor was locked.

Even so, the nature of the weapon meant not much impact could be transfered to the gearbox.
But Nick's right, if you want more than a small flail... get a fan motor. _________________ ( •_•)
I think it still had the orginal clutch on it but it was held in place by a couple of hose clamps. It basically just was a drill without its case still had chuck n clutch. And it only lasted for one event and I went through 2 gearboxes and 3 motors. Mind u it was easy at the time and prolly worked the best out of anything I've built. _________________ Steven Martin

Rob Purdy from Team Cosmos was talking to Andrew about how he did his drill mods and that is the result.... Now if everyone buys a bunch of Andrew mods, Andrew can buy a milling machine and produce those ones as well _________________ https://www.halfdonethings.com/

That is seriously cool! I want a set (or two). Looking at the parts, you would need a lathe and a mill with either a rotary table or a DRO to make that gear carrier. I wonder if this could be done for the Banebots/Whyachi motors? _________________ Australian 2015 Featherweight champion
