In part 1 of home made hinges i showed hinges made of aluminum socket head screws, in part 2 I am going to show hinges made from 6-40X 1nylon socket head screws. I made the mock-up using 1/4 balsa. I did the glue testing using slow cureCA glue. The holes for the screws were drilled with a 1/8 inch. copper tube drill. I used 1/16 music wire for the hinge shaft. I used a 1/16 drill bushing liner to drill the head of the screws. The screws will cut a thread into the balsa when screwed in , I put a lite coat of glue on the threads. After the glued had setup I could not get the screw out of the hole. I will be using the 6-40 and 8-32 screws for my hinges from now on with the 1/16 music wire shaft. The screws can be had from Mcmaster Carr for $6 per 100. I think a3/4 inch. long thread would be fine. This is a no gap hinge and no V on the balsa.
