you cant really see them in the pics... anyway, I need halp getting them out. also, About LED's, do I need a resistor If I am using LED christmas lights (4) connected to the same 9V battery? if so, what kind?

So I can't say if the epoxy would hold for 100 cocks or 10.

Try some penetrating oil to loosen the screws, then you can clean them off with naval jelly.

For the lights, count the number on the string and divide 110 by that number. As long as there isn't a transformer or resistor hidden in the string, that will tell you the number of volts each light needs. So 9 volts divided by the number of volts each light is supposed to get tells you how many you can have in series. If the number isn't whole by a decent amount, you'll need to put in a resistor.

To remove a rusted or ruined screw I usually drill through it (This works better with stipped screws). This prevents you from putting a new screw back in however. There are other methods for removing rusted screws, but i find drilling them out is the easiest for me.


As for the LED question. I think you do need a resistor. Howver, I am not sure what you would need.

Screws: Penetrating oil and a stripped screw remover bit, the rust isn't going to make a bit of difference in plastic, it's not like there was metal around the screw to rust and bond with the screw itself.

If you're using LED christmas lights... Dont. They'll burn out on you. Also, you have no way of knowing what voltage those LEDs are rated at, and that's the single most critical thing you'll need if you're going to wire them to any kind of battery source.

To calculate the resistor needed, you need to know the Voltage tolerance of the LEDs as well as the power source you will be using, it will be easier in the long run if you just start from scratch with LEDs.

Just buy some free-floating LEDs and wire them, the internets will teach you how. There's a fantastic voltage calculator out there for making up small LED arrays.

But if you must use LED christmas lights, find one of the small strings and just use all the lights with the built in battery container, I'm sure you can find some place to put it in the LS shell, there's a shit-ton of space in there.

saywat? small strings? Built in battery container? and btw, I'm putting them in my Maverick... I'm never going to be a good modder...

Yep. Battery powered Christmas lights. I have seen them at target and hobby lobby.

Don't say that. Like most things, modding takes experience to get better.

I look at some of my past mods and realize that I got better over time. I read many posts on nerfhaven and
instead of replying "oh that is so cool dude", I simply watched and learned. I tired what I learned and slowly improved over time.

I'm not saying that I'm a great modder. I'm not. But I am certainly better than I was a year ago.

Just give it some time and learn all you can.

Oh man, I thought he was cutting up an already battery powered string...

Oh shit son, you do NOT want to try and use christmas lights that were meant for AC power.

Go to your local radio shack and get some LEDs, talk to the guys there about resistors, the LEDs might even come with resistors.

While you're there pick up a battery cradle for a 9v or 2 AA batteries, you'll need it. Then check out google for how to tell what resistor you'll need to use, because a 9v and 2 AA batteries put out very different voltages.

The 9 volt puts out 9 volts and a AA does 1.5.
It depends on how you are wiring the lights, but you probably are going for the fewest wires, so you want the 9 volt.

ok, I got it, I'm using three little watch batteries to power two Christmas tree LED's no resistors. I am also using a five prong switch, any help there? like where to connect and stuff

Penetrating oil? Naval Jelly? This is really starling to scare me Boba

Anyway, you could either drill them out, cut them, or just use a bigger screw driver. That worked on my Nitefinder.
