Then today removed the motor from a microwave and made a rotary drier. (Bonus this MW had two motors so have a spare),
I used an old Dell monitor stand, added benefit is its adjustable up and down and the drier tilts.
The motor is mounted to wooden battens then faced with thin ply.
Taking the innards out of an adjustable roller catch (pic 1)I glued it to the motor spindle, this made a perfect
attachment for The piece of loft insulation I then bolted to it, so I can mount the floats securely. ( this has the added benefit, I can replace it when required).
Now going to attach a cardboard surround to collects the paint spray then ready for production.

CAUTION REF MOTORS
They are AC 240 volt motors. I ran mine with earth to housing. Positive and Neutral to motor connections.
DONT SPIN MOTOR BY HAND AND TOUCH WIRES IT WILL HURT
They can produce very high voltage instantly when turned by fingers!

Looking forward to doing this. hopefully will only need the MK1 version. Andy
