When I got the call to say the metal work was ready to be welded I took the chance to help out (I just stood back and watched).

Because I went for tab and slot construction it was a pretty quick process to assemble and weld with lots of attention paid to making sure that the parts were square but not necessarily dimensionally accurate.  All of the weather covers would eventually be 3D printed so I could amend the designs to account for any errors induced during welding. 

With all the parts welded up I loaded the car and took them home to begin test fitting,

The original plan had been to add in a few additional holes that I missed in the initial design such as the AZ home sensor (photos below) and ensure that everything would fit prior to sending it away for powder coat. Spoiler alert, I never account for the welds and they got in the way of the AZ stepper motor.

But....... it got the better of me and I ended up fitting all of the parts I had on hand and wired up a dodgy controller so that I could get some motion working.
