My plan is to NOT use switch stands that you touch. I will use Tortoise or similar. The switch stand will either rotate with the tie bar (see North Bank, above) or just not turn at all.
I guess if it really bothered me that the indicator could be set incorrectly with my non-rotating switch stands, I could have the indicator shaft set loose in the stand. If I were taking a photo or something, I could turn it correctly.
I would MUCH rather have an accurate scale-sized switch stand that did NOT turn than an out-of-scale one that did. I'm standing right there--I can LOOK at the switch points. If I'm running on the main, I can look at the signal indications.

chutton01 rrebell Trouble with the Caboose high level throws is the handle breaks sometimes, repaced a few and the grown throws are great but do the really have to be that large. I threw my lot in with those HO scale modelers who use Caboose Industry manual N scale throws in conjunction with Peco turnouts - plenty of travel in the CI throws for the points to firmly switch. Of course the N scale throws are only about 30% smaller than the HO throws, so they are still nowhere near prototypical size, but they are less obtrusive.

rrebellThe engineering can be done, but you need someone that knows engineering and where to get commercial parts for it.
Yes, I am sure the engineering can be done and the parts could be found, and I also suspect that the cost of the final product would be rather high if not outright exorbitant.

I understand the problems and all things do not need to be scale.

One talked about small gears, what do you think are in a small watch, not to say any of those are any use.
MisterBeasley Rix makes model throws that mount on your throw bars. They swivel with the turnout position, but they are indicators only. You can't use them to actually throw the turnout. With a Tortoise under the table, you get the illusion and the detail.

They would be so small they would be to delicate to with stand use and the forces applied to them

I think the challenge for making a working scale model ground throw switch machine is going to be the teeny tiny bevel gears inside. Making AND installing.
It takes an iron man to play with a toy iron horse.
I've never seen one of these. I tried ordering some, but they were sold out by then. The importer said he didn't plan on doing more. I neglected to ask why. I haven't seen any on e-bay, so it doesn't look like people are trying to dump them--thus implying they are worth keeping.
A full sized ground throw (as in 12" to the foot scale) is a 3 foot long 3/4" dia rod with a weighted handle about 4" x 4" x 2", plus the mechanics in the base to take the rotational motion and convert it to linear of the rail. (NOTE -- this is from memory working the museum, it's been a few years since I've been there)
Scaled down, that's 0.425" length x ~0.0115" dia on the mechanical throw (for comparison, tortoise switch machines include 0.025" wire), and ~0.046 x 0.046 x 0.023 for the handle. Pretty darn tiny ...

It is my understanding that scale ground throws would be so small as to present issues with both installation and operation. I am more than happy using the Caboose Industries ground throws on my layout.
We have scale cars and track, why no working scale switch stands? We have new materials and can print parts in metal. The closest I ever saw were from along time ago (not counting Harp type). These were from Model Engineering Works or MEW. These were great except for the large spring (could be done better today) and they broke easily because of the materials they were made from in the day, we have better materials today.
