Thread: Shed built SS tumbler (Photo Heavy)

D i b: How did you couple the motor shaft to the bottom of the drum (pail) base?

I've been considering making a tumbler along the lines of yours. I already have the wiper motor (left over from another project that didn't proceed) and other electrical bits needed, and some pails and idler wheels. Been pondering over different ways of coupling them up, bearing in mind that the pail must be readily detachable. What worked for you?

I tried my favorite go to glue but it failed. I then tried selleys all plastic fix glue. The primer comes with it and it's held so far. I found an old camera mount with a std m8 threaded hole and just glued it to the bottom of the 10L bucket. It's just rolling on 2 sets of rollerblade wheels too. All up that bucket gets fairly heavy eh.

Thanks for the info. So you have to unscrew the drum from the motor?

Surely there is an engineering/tool supply shop local to you for pillow blocks & collared bearings, belts and pulleys. Any 'Steel & Tube' should sell 19 mm stainless tube (used in dairy sheds) by the meter.
Your wiper motor should have plenty of torque and negate the need for pulleys to gear down a higher RPM motor.
Farrell Bearings in Hamilton have everything you will want if that is an option. Farrell Bearings

Many thanks for the scary terry link @Dead is better ,
I have been using this 12volt 5amp supply for a couple days now with no problems. https://nicegear.co.nz/electronics-g...-power-supply/
It came with a US plug, which would have saved buying the suggested NZ/AUST figure 8 plug, I would have been happy using an adapter and saved the extra $5. Very prompt service though.
The old wiper motor I'm using is slow but quite functional. As it was a perk, I'll put up with it for the time being before deciding whether to replace it or gear up the drive RPM up with pulleys.
I'm picking it is missing the high speed setting of a more modern unit.

I just rotate the drum backwards to get it unhooked. Going slow is the idea! I tried various loads at different speeds and the one at 30rpm was by far the best.
