The platform sheet is particularly heavy and sharp and hence dangerous to handle. It is very easy to cut oneself on the edge of it. To deal with this, we have decided to attach 1″ square profile Aluminum tube. We have done this by cutting four lengths of tube and cutting out each end a 45 degree cut to ensure they connect together around the perimeter of the Aluminum sheet neatly. We pot riveted these square profile tubes to the sheet.

 

 

Next I wanted to install the leg hinges. I want the platform to be about 40cm above the ground and  so with a leg length of 80cm, this means the legs must subtend an angle of 30 degrees with the platform. The side aluminum tube will provide a place for the legs to rest against to ensure 30 degrees angle is met. To get the angle of 30 degrees, we must place the legs a certain distance away from the tube. Please see calculations below.

 

 

I’ve started marking holes around and installing the hinges. See the picture below.
