Spring powered BB Gun

Step 4: Step Three

Now, put a holesaw on your drill with 4mm drill bit in and whatever holesaw bit you need to fit your spring tube, it has to be able to move in there, if need be file it down a bit if you dont have the right drill bit.

Then, throught the hole in the middle, glue the 4mm dowweling in.
Screw a screw in the top of your circle, the slide the screw down your cutting in the springtube, therefore compressing the spring, and then twist to the side, locking in place, this is how you cock your gun.
Put this in your spring tube.
