Pic 1.This stand works both indoors and out. Remove the threaded base spike for indoor shooting. Pic 2.The Quick release mechanism, that squeezes the clamp together around the main alloy tube. I scroll sawed the lever on my Hegner after drilling the hole. Pic 3.The top piece is in 2 parts. Turned and one piece then milled with a curved recess to take the top horizontal bar that is bolted from underneath. The ribbed rubber is in a recessed groove. Aluminium is great to route at high speed with a sharp cutter. Tiny flakes go everywhere. So wear goggles and keep your mouth shut.
