Prototype Production

I have started production on my prototype.

Here are the materials I am working with - Tubular steel x4, Steel rods x4, steel bar x8, Aluminium Tubing x2

I was quite lucky in purchasing my materials from a steel fabricators near my house and they offered my some good prices for the steel and also in cutting it.
I purchased the aluminium tubing (for the back rest) from Bunnings.

This is the overall measurements of my chair.

 With some assistance, I welded the steel bars together and then welded the steel tube to form the frame of the chair

 I then welded the steel rods to form the support

Then I cut the steel rods and welded them to create the sleeves for the back rest to slide onto
