The "four post" part of my model is just the beginning, there's more to it than that. It's very loosely patterned after/inspired by, the headframe of the Desert Queen mine in Tonopah, NV:

Thanks Ray, I understand what you are planning now.

Looks like the streak of rust across the shed roof has dripped off the winding cable ?.

The cable that has dripped rust on the hoist house roof isn't the winding cable. I think it's just a guy wire to help stabilize the headframe.

On this old mine the winding cable is hanging slack and is barely visible between the hoist house and mine. BTW, like many of the mines in the Tonopah area, this one used a type of wire rope called "flat rope", which I'm hoping to model on my headframe if I can find a suitable material.

That's a really cool, compact set up. Looks like there was a lean-to addition over the flat-belt driven air compressor in the foreground.

Ray, you may find the following photos of mine (pun) of interest as you want to model 'flat rope' winding cable:






Note the shape of the sheave wheel.













The cigarette paper packet measures 2 7/8"  x  1" .

Hope this helps.

Regards                                       Michael

Ray

See if you can find Chartpac tape for flat rope

Used to be made in all colors and widths, thin mylar with adhesive on one side

Don't know if it is a product of the past, but was used to make bar graphs and the like. Thinnest was 1/64" wide as I recall. Dimensionally stable. We used it for all kind of things at the model shop--but that was in the 60's.

Thanks for the pics! The sheaves are especially helpful. I've seen plenty of flat rope sheaves in Nevada but most of them have "bicycle" spokes, and I'd much rather model these simpler spokes.

I've ordered some flat, 1/8th inch wide braided kevlar that looks like it may be well-suited for replicating flat rope in 1/24th scale.

Some simpler sheaves for you Ray:

The first photo (with pigeon)(previous post) is of 6 spoked 'T' shape spokes.

Below photos are  4 spoked 'U' shaped spokes:



 










Hopefully of use to you.

You wanted winding sheaves ? :


A combination of multi-spoke & 4 spoke (these are round rope, not flat):








This 4 spoke sheave has axially flat spokes with raised edge flanges :







Above 3 photos taken at the rather dismally named 'Mina Te No Escapara' (no translation required).

Enough of mine winding sheaves, I've got a model railway to try to build !!.

But if you need any further info Ray please just ask.

Great pics, thanks! Where is that "mine of no escape"?
