I got this mount several years ago with a 12.5" cave f/ 7? I sold OTA. The mount came without RA drive and did not have pier. I got a 8ft. Section of 8" diameter well casing and planted it in ground with multiple bags of cement. Its served me well for years as a big refractor mount. It carried a eight inch f/12 achro when i had that scope and i currently use it for 5" f/ 15 and 140mm f/9 triplet. It really is great . It's 88" from ground to mounting plate, very comfortable stand up viewing at zenith, thing is i'm not really sure if its a cave mount. RA shaft is 1-13/16" . Wonder if anyone has seen this mount before but really interested to know if others have big classic mounts permanently set up on their property.
So who else has a really big classic mount permanently mounted in their yard?

Looks like a real workhorse!
I hope to join the club one day, just waiting for the opportunity I suppose

I don't believe that's a cave mount (I had one for years with a 12+1/2" newt on it) That looks more like a home made job with very good welding.
The setting circles do look like Cave's however.

I don’t know if I would call this a really big mount, but it's been living out on my back porch since “92”.
Having lugged a 706 around for 36 years, I can attest that it belongs in the large mount category. I haven't permanently mounted mine outside, but there have been periods when it has lived outside for months under a cover, back before I had an observatory. Even with that, now that I have adapted it to take a D dovetail, I'm still inclined to leave it out, polar aligned, so that I can just carry out various larger scopes to set on it, without disturbing the observatory setup (and when the snow is too deep to clear that far out).
I tend to think of "grab 'n go" in terms of the number of trips. When there is a mount ready and waiting, as long as I can carry the OTA in one hand and the eyepiece case in another, it's a one-trip grab 'n go.
The declination slow motion mod on yours is really impressive. If I were using mine for scope that's too long to reach the knob, I think I'd look into it as well. The 706 mounts are somewhat underestimated in value, being a bit crudely finished, lacking setting circles, and not being convertible to go-to. But they carry a ton, and the exclusive use of stainless, bronze, and aluminum makes them practically immune to corrosion from the environment.

I’m sorry, that was a bit off topic.
l do love my 706. A very simple and elegant design.

So this big alt/az mount stays in my back yard. Its 7ft from ground to trunions, the pier and legs are quite light but the mount head weighs a lot so when set up it doesnt move. I was told it was built by Ken Dauzat who did great work. Very steady for my 140mm f/9 triplet and even for bigger heavier scopes. Lucky for me i have it and love it.

Yep, 1986 Astro-Physics 706. They advertised a smaller version of the mount and called it the 504, but I have never seen one. I wonder if any were ever made?

I've got one that seems to be permanently mounted in my living room. Does that count?
