Thank you Gentlemen,
Steve your link is correct,ta.
Charles, I sometimes find my 43'' high tripod painfully low when using my cassegrain telescope, I am likewise 6' 2" tall so what sort of telescope do you use?
Stewart, thanks for your investigations, my base plate is a circle of 25 mm thick steel, 500 mm in diameter with a pair of bolts one each side of each web near the outside of the plate. I spent some time today welding the bolts, 16 mm threaded rod, into a frame to go into my cubic metre of concrete, 1 m *1 m *1m hole dug and an arcmesh box welded up to sit in it and around the bolt frame.
With this plate and the four gussets flexure at the base of the pier should me minimised.
All this may seem like overkill as Andrew suggests, but do it once and do it properly.
Chris
