Simple E-Conversion?

Whao, thanks. That webpage is like a maze. How many times are they going to ask if u want more info on a solenoid?

And btw, i tested out the pull on my tippmann and i got 32 ounces . Either thats a ton or im doing it wrong. I just took stuff and hung it from my tippmanns double trigger. It seemed to work better on the bottom of the trigger but i dont no. Im going to go test how much it is to push up the sear enuf to trip it to shoot.

Anyone else have any ideas on how to measure how many ounces it takes to shoot my tippmann?????

yeah, you can't use the trigger to measure weight/force. you're not going to attach the solenoid to the trigger are you?

not to maention, of course it takes less weight to pull the trigger farther away from the pivot point. it's called leverage. that's the whole purpose of a double trigger.

you need to figure out how to measure the force it takes to move the sear. it will more than likely be somewhere between 2-4lbs. which will need a large solenoid, and a larger battery.

most guns take more than you think. the cocker is about the lowest one I've measured.

a stock classic automag takes about 6 lbs!

don't take this wrong, but I think you need to study up on mechanical and electrical information before you buy anything or modify anything. I like you enthusiasm, but do some homework first. your not going to understand solenoids, or how to control it. your not going to understand how to mechanically modify it to work, if you don't. take your time, and do it right. study other peoples tippmann modifications. study the tippmann electro grip. get some ideas from them. use what's out there along with your ideas you get from learning about the stuff to come up with your own design that fits what you want to ge out of it.
ask yourself "what am I really trying to accomplish by doing this?" is it just as a fun project to make the trigger easier and the gun more fun to shoot? or am i seriously thinking I'm wanting high performance?

it will be more rewarding if you learn how to do it without asking someone to hold your hand through the project.

make sense? I don't mean any of this in a bad way. like I said you've got the main ingredient for success, and that's enthusiasm :)

Ive done all my research on caps and solenoids and such like that. Problem is is just finding a solenoid that will have enuf force to trigger the gun. And right now thats pretty slim.

Instead of a bigger battery i was looking into putting some old disposable camera caps in a series for the umph. Im still workin on it tho so give me some time. All the soleniods ive made, dont seem to be powerfull enuf so i figure itll be easier to buy one.

okay good.

well, have you thought about going with a micro 3-way solenoid valve and a small ram?

kinda like tippmanns e-grip only smaller. of course then you would have to get a lpr inthere too.it's just that when you need a lot of force in a small area, pneumatics will always beat solenoids for power. it is more complicated that's for sure.

here's one I did for my homemade e-mag:

but really, that solenoid site has what you are looking for. it's just figuring out what you need. you only need to move the sear how much? in other words figure out a minimum length of movement needed to get the sear to trelease the hammer properly.
then, reduce the force the hammer puts on the sear by reducing the hammer spring weight. I know this can be complicted since the tippmann is a blowback, but I believe somebody like maddman sell a spring kit for the model 98 and the A5. I think G3PB.com has them.

the object is to first improve the gun. reduce the needed stroke of the sear and reduce the needed force to actuate it. then start looking for a solenoid. solenoid city will have something for you. I can help you pick the wire size to get optimum performance for your load and the power source you are using.

my old original e-cocker design (about 5 years ago) used a fairly large solenoid with an RC car battery powering it. I slip the battery into a band of neoprene I had on my tank. eventually I found a smaller, more efficient solenoid at solenoid city. then I started using caps to help the battery. I eventually got it down to this:

and then built another one:

those both get about 20,000 shots per charge and can rattle off paint as fast as you can feed them.
