Progress 2

Finally cut some holes on the receivers.


Even with the help of my friend (should I say who?), the holes aren't perfect enough. Using only a penknife to cut, it's not good enough but still looks decent.

Also I bought some stuff:


I bought a spring powered foam dart gun, some BBs, a 4x20 scope and scope mounts. Let's take a look at the scope.

What's under this wrapper?


A scope!


I tried to take a picture of is it like when looked thru the scope but I can hardly get the crosshairs on camera. You have to be totally parallel with the scope to get a clear view of the crosshairs.


The scope diameter is smaller than I expected. But how high can you expect from a $19.50 scope? The next best scope cost $71!

Progress 1.1

My father found this nifty 1 metre steel wire which I'm (hopefully) going to make a spring out of it. It will eventually be the magazine spring as it is strong and thick.


It is hard to bend it but that's what you get if you want strength. It's about this thick (I'm lazy to measure). This 'wire' is so rigid that it might just be a very thin rod and not a wire...

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.

Think it's cheap? I don't think so

Yeah, it is more expensive then it seems. The following is a list of what I've bought/going to buy:

Stuff I've bought:

Plastic cardboard: $6.00 for 2 sheets
Utility knife (penknife): $2.50
50cm metal ruler: $5.00
Masking tape: $2.00
Duct tape: $2.00
Craft knife: $3.00
10mm dia. acrylic tube: $4.35
6mm dia. acrylic rod: $3.42
500 sheets A4 paper: $5.00
Hot glue gun w/ 5 glue sticks: $7.50
Super glue: $1.00

Sub-total: $41.77

Stuff I'm going to buy:
Nerf Maverick: $21.90
Airsoft BBs (1000): $12.00
Mini drill: $16.90
Air dry clay: $20.00 est.
Rifle scope: $19.50
Rifle scope mount: $10.00
Scope rails: $10.00
Spray paint: $10.00
15mm dia. PVC pipe: less than $10
Steel/copper wire for spring: $????
20mm and 10/8mm acrylic tube: $????
Sub-total: $120.30

GRAND TOTAL: $162.07 (add $30 more for misc. items).

I never expect I have to spend so much. It would certainly be a lot cheaper if it's just a model that can't shoot.
