Anyone own or have information about professional rock tumblers?
Hi,
I'm trying to work out how much power I need to turn a rock tumbler barrel, or more precisely how large a barrel I can turn with a particular motor. I have a nice little shaded pole induction motor which is rated at 30 W and runs at 1425 rpm (probably the full load speed is somewhat lower). Does anyone own a small professional tumbler? If so I'd be very grateful to know the information on the motor data plate, the barrel capacity and barrel diameter. The Thumler Model B tumbler looks to use a motor similar to mine and has a 15 lb capacity, but I can't find an official figure for the motor rating anywhere. I was thinking of perhaps two 1.5 lb barrels or two 2.25 kg barrels, depending on cost and availability. The rubber barrels seem very expensive (£30 upwards for a 6"). Anyone know why or where I might get them cheaper in the UK? There's a picture of my motor he http://www.mythic-beasts.com/~cdt22/...pole_motor.jpg Ignoramus, let me know how your project goes. I'm planning on building a nice desktop model rather than a hardcore redneck model (not enough space in the shed!) but I'd be interested to share experiences and pictures. Many thanks, Chris |
