Prototype Production

I was forced to resort to plan B, as welding the backrest together didn't prove successful.

Because the Tubular aluminium steel was too thin, welding it together put holes into the tubing.

With insufficient time to re do the whole process again using different steel, I decided to go and use a different material for the back rest.

I went to Bunnings and got a meter long sheet of plywood to use as the main back rest.

I basically used the same outline and shape of the original backrest.

After cutting out the outline i used the left over aluminium tubing to use as the supports to hold up the back rest.
