Just an idea I had in my head before spotting the EQ mount in the shed. Obviously you can adjust the height, the distance the binos are away from the centre pole & the horizontal & vertical directions. Using perhaps 30-40mm pipe, 2 3/8" nuts & bolts 2 bigger dia. pipe sleeves, 3 bits of rod or pipe for the tripod base, a bit of welding, paint it. Just an idea..
