At least there's a lot of room in the Maverick to tuck things away...

F = 50 newtons
L = 1.75 inches = 0.04445 m
μ = 4π E-7 Henries/meter
A = .0625*π square in. = 0.00012667687 square meters
N and I variable.
The way things are looking now, I will either have to get a very good conductor or wrap a lot of wire in order to get 11 pounds of force over 1.75 inches. I've already looked into linear actuators and other motor-driven solutions, and those are far too expensive for my tastes.
For constructing this solenoid, I was originally intending on using a 7/16" steel rod inside a 1/2" PVC pipe, wrapped with however much wire I needed.
Are my numbers off somewhere?

Don't solenoids actuate pretty fast? Why not replace the spring with a soloniod?
I thought about this, and decided against it for three reasons: 1, because I want to still be able to fire this without a battery, and removing the spring altogether would prevent that; 2, because I would have to make the back of the Maverick longer in order to fit the solenoid; and 3, because I really want the slide to be thrown back during the firing process to make the blaster more handgun-like.
Why don't you just hang paper clips on a string off of your maverick until it cocks. Then see if your solonoid can lift that much weight? That should be a fairly accurate way of finding out that information. You should probably start with one pound weights, then when you have enough 1lb's to cock it, remove one and start with the paper clips (or something similar) until you can narrow it down to the exact force. Then it's just a few simple calculations and you're done.
Ah, thank you, that would work nicely. Now to find some paperclips, string, and a scale! I'll be sure to post approximately how much force it takes to cock the slider, in case anyone else happens to need that information.
A solenoid is a coil of wire...electric wire is bendy. Therefore, you wouldn't be able to fire. The solenoid would just coil tighter and stay that way.
Actually, the solenoid would generate a magnetic field that would push a metal bar forward. The coil itself wouldn't do any physical pushing, so it doesn't matter how bendy it is.
Edit 1:
Rounding up to compensate for errors in measurement (I used a fairly inaccurate bathroom scale, as that's the best my parents' house has to offer), it takes about 50 newtons (or 11 pounds) of force to pull back the slider on my Maverick.
Edit 2:
I apologize for my ignorance, but should I keep using this thread for further questions and updates relating to this mod, or should I create a new thread?
