Sheaves

[RiffRaff54]

How would I go about making a large diameter sheave or pulley. I'm looking for the spoke design like in this picture http://www.dodge-pt.com/products/pt_...es/sheaves.jpg
I plan on having them rotate, but they won't be doing any real work.

Thanks

Go to your local industrial salvage yard, I bet they have a couple hundred of those.

What Diameter are we talking about? Do you mean you want the stle illustrated in that picture but on a much larger scale, for , say, and industrial looking setting ? If that wer the case I'd simply jig them out of Luan and build a steel or wood frame to mount them on from behind. install a central mount point for a moto and you'd be in business.

I'm doing Machinal and i want the entire space to look like a machine, i want that style on a huge scale, and i was thinking of having them connected by belts so everything fits togeather.

I like Vans idea of luan with a frame underneath. With some careful design work you could make them 16 feet across if you wanted.

Then hit the salvage yard for some smaller ones to use in the foreground.

Rotating equipment and belts, "real" or otherwise - Just make sure everyone keeps their fingers out and watch for loose costumes, trailing costumes, headset cords...

My theatre did a bunch of big gears and little gears for our production of "king Lear" last year


We drew out the big gears using paper and a compass and just made a sandwich with luan on top and bottom and syrafoam in the middle, and then we used 2x4 as the spokes on the big ones and 1x4s on the smaller ones. and all of ours turned I think. I just don't remeber what we did for the pivots.

um... here is the only pic I have, but I will post more, maybe tomorrow or thursday.

Hope that helps a little, um... will look and see if I can find the origanal designs.

Wow, thanks! I'll throw that idea to the TD and see what he thinks.
