So here's a basic idea for a tripod. Using my existing 8" strobe arms, clamps and a handle post attached to three Sea and Sea ball adaptors from Mr Leung of ebay again.
Here's a video of the first test in 2m vis and 10c temp. Hurry up summer!
To fit the balls to the handle bolts 2 adapter holes were enlarged to 8mm. Another hole was drilled in the tray to attach the third ball.
