belt tensioning for a spinning weapon

im finialising plans for a feather spinner but im not sure about the best way to tension the drive belt for the weapon.

with my current robots i use belts for the drive and i tension those using a motor bracket that slides to either loosen or tension the belt and then i would then tighten the bolts on the motor bracket to hold it in place, would this work for a drive belt for a weapon???

althought i know it would in theory work (as it does in my current robots), i didn't no whether it would be best to have a spring loaded tensioning system to allow the belt to mabye give a bit if the spinning weapon was suddenly stopped.

any one got any advice?

thanks for now

If you carefully design and machine something then you shouldn't need tensioners.

If you do then make sure that the tensioner is able to rotate ie a bearing on a bolt (this is what I use on hornet) otherwise your belt will heat up and snap.

I prefer to mount my disc and motor solidly and have the tensioner either spring mounted (can be difficult to machine) or on a sliding channel like you described.

right ok so ill stick to what i already know- a sliding motor bracket then.

thanks for the advice
