I was originally gonna control the turntable with an Arduino controlled motor but after discussing things with folks on the "track" part of this forum I've decided to go with a manual control for simplicity.  I found the parts for this at McMaster-Carr.  They have a small handwheel (3 2/3" dia) with a dial indicator in the center.  This has a display set up like a clock with hour and minute hands and 12 positions around the dial.  I'm planning to replace the dial with one showing 40 positions.  The output from the handwheel will go to a right angle gear reducer with a 30:1 ratio.  I'll use a toothed pulley on its output connected by a timing belt to a pulley of the same size beneath the turntable.  With the 30:1 ratio every full rotation of the minute hand on the handwheel will move the turntable exactly one track position.  With the minute hand at the 12 o'clock position the turntable bridge and the track will be properly lined up.  It will take 30 turns of the handwheel to move the turntable 360 degrees.  Movement of the turntable should be slow enough to look realistic but a full rotation might be a pain in the wrist.  I don't expect there to be much more than 180 degrees of rotation needed very often.  I think I'll use a switch controlled solenoid beneath the turntable pit to lock the turntable into position.  That's my plan.......

It does look like there may be circles on the diagram which represent them

Yes, I compensated for the 12" X 12" posts and the width of the 30" stone walls.  Thanks for thinking of that though.
Helmut - true, not exactly eBay cheap but I thought it would add some fun to the operation.  Besides, looking at production turntable prices I'm still all-in for less than half the price and I'll have something unique.

Helmut - Kinda funny.  Your comment about the price made me look on eBay.  Found one new for $40.  It'll be delivered Dec 12.  Thank you for the inspiration.

Tom,

It might not be that hard to justify some sort of barge or ferry.  When Owens Lake had water, before the Los Angeles DWP drained it, there use to be a steamship that traveled across the lake hauling mining supplies from the ex-Carson & Colorado on the west side to Cerro Gordo on the east side.

I believe that the steamship sunk with a shipment of gold with it...never to be found.

The smelter use to pour 500 pound gold ingots so that thieves couldn't run off with it.

I'm sure you could invent some excuse for at least a small ferry that transports maybe 4-6 freight cars.

Oh! Just found the photo online, https://en.wikipedia.org/wiki/Klamath_(steamboat)

Michael - OK, that works.  This is free lanced anyway so I'm not really stickin' to reality.  I like the story about the ferry fulla gold.  The lake is now dry and still no sign of it huh?  When did they drain the lake, in the 30's?  So maybe it's buried under 80 years of silt.  500 lb ingots of gold?  You could probably do a flyover in a Cessna with a metal detector and still see that.  Sounds like someone made off with the goods.

The C&C actually ran on the east side of the lake.  The Cerro Gordo mines are also on the east side, in the Inyos, somewhere in the 9-10,000 foot elevation. Ore was originally freighted down to Swansea near the lake for reduction.  Yes, I believe I remember reading that there were one or two small steam vessel that traversed the lake serving some of the small communities and resorts.  They worked out to about an 80' beam if I recall.  Kind of like the Tahoe steamers of the same era. You can see how high the lake was before the great water theft of the 1920s if you look closely while driving around the lake.

If it were something that you were entertaining a water to rail operation can be quite interesting.  I am going to do one in Central Nevada since I can't model it the way it was, I've decided to have a bit of raucous fun in the vein of the days newspapers. The Reese River Navigation Company! An invention of a 1940s Reno Harold's Club promotion as a fun way to try and make Nevada history "more interesting" as if it needed that!  The "river" has never been very wide, in fact it was once claimed that the trout had to have their sides regularly greased so that they could get through.  Mark Twain, Dan DeQuill and above all Fred Hart would be proud.

Steven,

You're right.  My mistake.  Espee's Jawbone Branch ran up the west side to Owenyo just a little north of Lone Pine.

Owens Lake went dry in the 1920s after LA put in an aqueduct.  After decades of litigation DWP is putting some water back in the lake.

When Leadfield in Death Valley was being promoted some of the brochures had a steamship on it!  Little lead, or anything else, was found at Leadfield and the rush and the town quickly died.   http://mojavedesert.net/mining-history/leadfield/
