For immediate sale: Large heavy duty permanent pier made by AB Engineering. This pier has never been used, and is still at the manufactuer's facility. I am buying the German equatorial head, which also includes the pier, but since I have a concrete column already in my observatory, I can not utilize the pier. This pier weighs 300+ lbs, 10 inches in diameter, and 42 inches high. The baseplate is triangular with fin supports to the column.
Note that this pier has the side gussets that terminate at the primary support bolt hole (the reason the little tube is at the base of each gusset to have direct load path off the gusset to the base plate) which bolster the tube effectively increasing the diameter of the tube. The base has a 12" radius, so overall, at least a 26" square/round, or larger pad would be needed. More details on this by request.
It has a beautiful dark blue finish which matches closely to the Meade SCT's. An optional 1 inch steel plate can be welded to the top with threaded holes, or rods to suit your specific needs at no cost.
Asking $700 and pickup in Fort Wayne, Indiana. If shipping is desired, the buyer will have to arrange for the shipping company to crate and ship the unit. Buyer pays all costs related to shipping. As a comparison, the pier Meade makes for the 16" LX-200 is priced at $1995 at OPT. This pier is 1.5x more massive than the Meade unit in terms of weight.
Please note that in the image, only the pier is included and for sale. The GEM head is not part of this.
I have a PDF file by request that contains more detailed images of this pier.
