Well after adjusting the legs and making good use of a spirit level I’ve managed to increase the stability of the turret to beyond that of a 3 legged goat.

Next task was to cut the bottom of each leg at an angle so the entire surface of the leg would make contact with the floor whever it was placed. This was very much trial and error but I did use a fancy protractor.

I have some foam sticky pads to add to the legs just to increase grip that little bit more.

Here is a shot with the fixed side panels fitted.
