Workshop

Aluminium sheet for the sheet and back rest, a steel sheet will be weld on to the steel tubes

Got my aluminium sheet done laser cut and bend at 95deg angle. 

Chop off the back rest a little bit so can be inserted to the original back support.

File the edges so it becomes more smooth and has no sharp edges

Finish to make a hole on the original back support. 

Remove the nail and some wood filler inside the hole on the original legs

Fill it up the hole using this coloured wood filler

Here is the result

Adjusting the legs to the steel tubes 

All the legs are set up

After powder coating

I chose matt black which have some texture on it so the seat won't be that cold when people sit on it. 

   

I used blind revit to attach the seat and the aluminium sheet underneath the seat. 

I used this primer before apply the spray paint

Apply the primer for all the legs 

Matt black spray paint for the original wooden back support and legs

The matt black turns out well!
