Re: [Losmandy_users] Pier top plates & how do I install a G-11 head to a concrete pier?

Sorry for the double post, but I'd like to kill 2 birds with one stone.



Background: next Spring, I want to build a bigger observatory. I want

to have 2 concrete piers. One for the 12" LX200 and one so I can

permanently install my G-11. I would like to be able to remove the head

and travel to star parties and such.



Here are my questions:



1. For LX200 users, does anyone have any feedback on this product:

www.pierplates.com



2. For G-11 users: those of you who may have mounted a g-11 in an

observatory, is there any guidance you can give as far mounting the

head on a concrete pier? I see plenty of products for assisting with

SCTs, but not for Losmandy mounts. As noted above, I would like to be

able to keep the mount and OTA setup in the observatory except 2 or 3

times a year when I would pull it off and use it on the tripod at star

parties.



Thanks,

Alan

I used the Meade field tripod adapter to mount my G-11 on my steel

pier. I don't see any reason it wouldn't work with a concrete pier.

It works fine for me.



It is available from Losmandy for $90 or maybe $10 cheaper from the

various retail outlets. See www.losmandy.com/access.html

That's a place for me to start. Now I'll need to figure how to mate the

tripod adapter to the concrete, or something similiar.



Thanks,

Alan

Well, if you haven't poured the pier yet, you can just imbed a 1/2"

bolt in the top to mate with the 1/2" hole in the bottom of the adapter.



If the pier is already poured, you can use a concrete drill to drill

a hole in the top of the pier (you can rent one for a few bucks)

and then use epoxy to imbed the 1/2" bolt in the top of the pier.

You can get epoxy that is intended to be used in concrete. I

once supported the base of a 35 foot antenna with a bolt epoxied

into the concrete sidewalk so it's plenty strong.



You can also get much more involved and bolt a 1/2" plate to the

top of the pier and use it to level the mount. I did that with my

steel pier and it worked like a charm.



Good luck.
