The end handle was made out of acrylic rod and turned out on the lathe. The metal tube was a cheep, old scalpel handle that was the exact size I needed, so i just used that after I polished it up.

I didn't make the inside mechanism out of fast cast I just maid it out of MDF and sanding sealed it. when it was ready I sprayed it with white gloss. I didn't cast this piece because it is hidden under the plastic tongue so wouldn't be seen anyway. Also the mechanism wont work so I just made an interpretation of it.
