G11G Pier

Russ All Messages By This Member #80279 Looking for recommendations for a permanent pier.? I'm currently using an adjustable Pier-Tech 2 (electrically operated to raise/lower pier) but I'm looking for a more permanent solution for inside my observatory.? Once installed, I'll be selling the PT2.? Hoping the bottom 'holes' are universal and will fit my bolts that are embedded in the concrete pad below it.

I am thinking about getting an 8" pier for my new G11 from this company. They say it would take about a month.
Nikul Suthar #80281 I got iOptron Permanent pier and Losmandy Male adapter that got bolted onto the hole pattern on iOptron permanent pier... I filled in pea gravel inside iOptron permanent pier for dampening vibrations. It gives great stability even with my 45lbs heavy RASA11... toggle quoted message Show quoted text On Wed, May 24, 2023, 12:03 PM <peter@...> wrote: On Wed, May 24, 2023 at 01:01 PM, Russ wrote: Looking for recommendations for a permanent pier.?

Brendan All Messages By This Member #80288 Russ years back i got a local welding shop to source scrap pipe I think it was 1/2" wall, 10~12inch dia metal pipe....weld a base and top (drill bolt holes to match Losmandy MA and base bolts) Added some gusset ribs (which were too long) .....and powder coated black.? Asked them to non prioritise do it when they have no other work.? Second hand scraps OK?? Like top Plate 1/2" bottom plate 3/4 inch Now of course setting the pier height is an issue you need to get right.?? I would have done it shorter and use .? But this raises the cost.? My pier cost was $900 Aud? (8 years plus back) and weight a huge amount.....But was perfect....I left a decent top plate hole to add builders sand if I had resonance.?? I tried to do natural resonance freq cals but it was beyond me, my guess the natural resonance was 1/4 wave of pier height. Suffice to say it was a battleship way over kill but a beauty??? A cheaper alternate was a concrete pier with rods to set into it for top plate? Of course the double plates to adjust for level is completely not needed FWIW.? . -- Brendan
Russ All Messages By This Member #80292 Wow, never realized how expensive these piers are.? I'm even considering taking my current PT2 and maybe filling it in with sand/gravel and just using it as a fixed pier.
Brian Valente Member Profile All Messages By This Member #80295 I have the SkyShed piers, which have a plate designed for the Losmandy MA adapter. works great, not inexpensive toggle quoted message Show quoted text On Thu, May 25, 2023 at 9:30?AM Russ via <njrusty=[email protected]> wrote: Wow, never realized how expensive these piers are.?

Brendan All Messages By This Member #80298 Well $900 Aud is around $650 USD.? But that was years back. ? Id expect try a local shop get quotes. Ask for scrap leftovers and non priority? mine overbuilt for sure ! -- Brendan
Chris Aparisi All Messages By This Member #80335 Russ, there is a huge thread on CN called pier engineering. Good read. Filling with sand/gravel is not something you want to do. That thread will explain why. The author also has a pier company.?
Oberon510 All Messages By This Member #83814 Old thread but hoping someone has picked up one of these commercial piers and could rate them. SkyShed is ~1/3rd the price of ATS. Maybe it is a steel vs aluminum cost decision. ? Thanks, Ken ? ?
