Altair SkyShed Pier

[GCG-Observatory]

Has anyone tried this with sinking the L-shaped bolts into the setting concrete using a template of the pier bolt holes? Personally I would think this was easier as drilling into concrete is not fun. Surely with the amount of adjustment on the pier that exact placement of the bolts isn't particularly vital?

That’s exactly how it was done with my recent pier/observatory build.  The four rods were bolted through a plywood template and this was used to push the rods into the wet concrete. The top plate  on the Altair pier is adjustable so you don’t need to align the base section particularly.
