Very nice! What precautions did you take to make sure that that silver paint didn't chip off the copper? And what is all that tape towards the back of the tee?

before painting I sanded it then i sprayed it with oil remover spray and then washed it with water and dryed then painted 4 times :wink:

and thats not all tape only the blue is tape black thing is like rubber hose that shrank? when you heat it 8)

and thats there because : http://www.putfile.com/pic.php?img=5981417
you see that aluminium thing in the picture, thats is used as reducer at end of the pipe where piston is ,and that is hold place with 8 small bolts that leaked so i coated the pipe with epoxy glue and for better look i putted the rubber hose thing over that :D

I hope you understanded something of that, I spent about 1hour writing this :D :D :D
