Progress 1

Because I haven't gather all the items I need, I can only do this far for now. Using plastic cardboard, I'm making the upper and lower receiver (body) of the gun.


The white dust/ash thingy is produced by the super glue during the curing process. Somehow super glue isn't really super for this. I found that the super glue is very brittle, a small amount of force can break it up. I wanted to use hot glue to reinforce it but with shaky hands + slow melting glue gun, I got this:

Version 1 of the upper receiver

As you can see, the ugly lines of hot glue is the reason why I have to redo this. I used a different method for this version 1 upper receiver, consists of 3 long strips glued together. Because of the flexibility of the plastic cardboard, it was a pain in the butt to keep it straight and glue it down. The thick glue can also affect the sliding of the bolt and might jam.

The rectangle holes at the front was supposed to be 4 rounded rectangle holes on each side. It is darn hard to cut the 4 holes without screwing it up so I intended to glue 6 dividers afterwards to form the 4 holes. Turned out I screwed up my calculations (maths fail) and this is abandoned.

Just for fun:


Made this in 10 minutes to simulate the bolt mechanisms. Trying out the extractor, ejector but no firing pin.
