Hi Folks
I have a Tall solidly built general purpose pier for sale. It is designed to be buried in a concrete footing to match any height your obsevatory requires.
Height: 1860 x 6.5 x 220 mm Steel Pipe (incl welded ends, not loose end)
With: 3 x 250 x 250 x 10 mm Steel plates, with 4 10.5 mm holes at approx. 220 mm centres.
Includes: 4 x marine grade (316) Stainless Steel setscrew hex bolts.
12 ‘’ ‘’ nuts & flat washers
8 ‘’ ‘’ spring washers.
Weight: 75kg (with packing & bolts)
As the pipe is so thick and stiff, no buttressing is required, no vibrations are seen as long as the base is anchored to at least 1 cubic metre of reinforced cement. Bury a former in the concrete holding 4 x 10mm high tensile bolts, or 4 x 10mm gal threaded rod. This pier is the little brother of the one I'm using, mine is twice as tall and I don't get spurious vibrations.
The top plate allows for levelling, should the concrete settle and tilt over time.
A sub mount plate can be fitted to match your telescope.
Asking Price: now $1,000 Freight Free, (or best offer)
Please pm to discuss, freight will be to couriers's depot.
Also I will consider having it cut and transformed into 2 piers if anyone wants a smaller pier.
Regards,
Danny
