2700 trigger replacement

Post by ark333 » Mon Aug 11, 2008 4:29 pm

Hi again, how are you guys ?

it´s been a while since I last posted here, with this 2700 problem. Finally, I was able to open the gun and repair the trigger, following the guide in this page. But after little use, it cracked again, and I see a waste of time trying to seal it again, cause a new break will eventually occur for sure.

I want to made a brand new trigger from scratch, one identical to the original 2700 trigger, cause I don´t like the wire trigger. Having the original as a model, do you know where to request this kind of work ? maybe at a factory ? I dont know if this can be done at home, this sounds like something more proffesional to me. Thanks for your help.

Welcome back.

You'd have to look at rapid prototyping places but those places are expensive. I'd suggest cutting a new one from plastic sheeting and trying to duplicate it as closely as possible. Most hardware stores have a limited selection of plastic sheeting that should be plenty adequate. The hardest part would be cutting the alignment grooves but if you have access to a mill it shouldn't be too difficult.

Someone at a local machine shop might be able to do all that for cheaper than rapid prototyping too but I've never looked into that.

A wire trigger with a plastic part acting as the trigger could work too if you want something better than the wire trigger that's easy to make and cheap.

Buy a 1/4" thick sheet of Lexan or Plexiglas. Trace the shape and you should be able to cut it with a box cutter, metal band saw, jigsaw, dremel tool/cutting wheel, whatever.

Getting one machined or printed in plastic is going to be a bit of a hassle, but if you have to do that, search online. There are a bunch of services that don't charge much and they'll mail the item to you.

There is always the possiblility of making a silicon mold for the broken trigger to go into, and then melt or pour some liquid material (possibly plastic), into a hole you left for the filling. Then you wait a day or so, and then it will be nice and solid. However, you would need to melt or make your own plastic, so that could be costly.

A mold's an interesting idea. While it would be a little difficult, you might have luck using a mold and epoxy putty given that the material the mold is made from does not bond with the epoxy putty. That would be reasonably cheap and could make a near duplicate of the trigger. Though, finding a good material for the mold could be difficult. I think cutting plastic sheeting is the most straightforward option.

Molding silicon, I have heard, is fairly cheap.

Here is a link to the process:

I was going to suggest making a mold as well. Seems like the other couple posts have it covered.

BTW Instructables is a GREAT site :) I'm on it every day :p
My "arsenal": Customizable APH, Storm 600 pistol (still haven't finished fixing this), launcher- Model:AB1.0(Decommissioned), AB1.5, soon AB 1.1(2"rebuild) maybe ill get something else in the future

That's a nice looking method. I think I'll try something like that in the next few months... it'll definitely be useful to duplicate little parts.

Something to think about for the future: we could make a bunch of relatively simple pieces like some triggers and resell them when needed. I've been considering that for repairs once I get some access to stereolithography equipment.

Yes, I agree that instructables is a great site.

The molding method could potentially be used for smaller pieces, but I just can't see it being used for cases, etc.

Isn't stereolithography expensive but accurate Ben? I believe
Boltsniper used it in Nerf, but the materials are crazy costly. It could be interesting though...

When you're at a university usually they give you access to all sorts of CNC stuff for free. That's how Boltsniper did it from what I know. I know nothing about how to work it but I know what building it's in at University of Maryland. Eventually I'll have it figured out and I'm sure I'll use it.

If you're in the engineering track at a university you'll have access to CNC machines, etc.

I hadn't seen that mold article before but it looks good. I do like Instructables too - but there are too many updates to their RSS feed.
