Aluminum ship is finished

Finally all the parts are ready the next thing to do is grinding all the extra aluminum from the pouring. I used a grinder for cutting off the extra big chunks, metal chisel then sand paper (600 grit), after coarse metal wool and finally a fine metal wool. I could keep on polishing until it will look like a mirror but at the moment I am happy with the way it looks.
To attach all the parts I used a metal adhesive after all its just going to sit on the shelf. Another option is using aluminum welding or very small screws to attach all the parts.
I used the star trek insignia as a base for the ship drilling a 5mm hole for the metal rod.
