When you do get a screw driver it might need a little further tuning. Most of the micro screw drivers I've seen are still too pointy to fully engage nerf screws - which strips the heads instead of turns them. You'll need a hand file, sand paper or even a small patch of semi-smooth concrete. Remove a screw and sand/file down the tip of the screw driver until the nerf screw can sit on it without wobbling around. The flares on the screwdriver tip needs to reach all the way out to the edges of the screw head.
A good screw driver is the single most important tool a modder can have. It sucks to be so limited now, I hope you're able to figure it out. Maybe if you can convince your dad to "help" you mod, you'll be allowed to use his tools under his supervision and find a father/son bonding activity (or better yet - he'll get you your own tools so you don't have to use his! Heck, my 6 year old has his own tool box full of real steel tools and he keeps them together and in great condition. (harbor freight ftw!)))
Sadly, I can't think of a single significantly effective mod that doesn't start with opening a blaster up to get at it's internals. Scratch that. You can go old school and "band" some blasters. You can run bungees or rubber bands from the barrel to the pull rings of nitefinders/firestrikes/messangers... (pistols with an exposed pull ring). That'll let you significantly increase the power to the plunger head without even opening up the blaster. Just make sure the right and left bands are pulling evenly on the ring or you'll loose power / break your priming rod. If you add too much pull, the additional force will over power the catch spring so you'll still have a limit there.
