Alrighty, here's the deal. I just finished constructing my first K9 special, and I have a problem. When I try to cock it, I can see the trigger move as if the catch was engaging, but the plunger seems to stop short just before the catch can engage. It's only off by less than half and inch, and I can't seem to figure out what the problem is. If anyone could help me with this dilemma it would be greatly appreciated. I have studied and worked with the internals of the PAS before so I have an adequate understanding of them, and i can get pictures if anyone needs them.

As stated in the title, I need to attach a bike pump to a titan air tank. I searched, but didn't find any detailed write ups or even internal pictures of the various mods that have been made involving bike pumps. From what I've seen, I will probably need to get a bike tire valve and attach it to the titan tank, unless there is a way to attach 1/4 size tubing directly to the bike pump. If anyone can help me with this dilema it would be much apreciated. I appologize if I missed something in my searching and/or am being a total dumbass.

I have seen check valves as part of the rigging for frankenstein guns, and I am planning to make one of my own as soon as I get the parts. So my question is, what does a check valve do, because it may be useful for me to know about these in the future of my modifying career. Sorry if I'm being a total noob with this question, but I will be greatful for all replies concerning this question.

Ok, so here's the problem. I recently sold my friend a modded big blast that he commisioned me for, and he went and showed it to all the airsoft junkies in my school, and now someone else wants a big blast. I am hoping for more buisness in the future, so I really need to fix this problem. And the problem is ..... that the pumps on the previous two I have purchased have been faulty. It seems that the O-ring is not thick enough to make a good seal with the pump tube. I tried fixing one by putting E-tape under the o-ring in order to rase it, but that didn't work. I fixed another with an O-ring from an oldstyle big blast, but I don't have any more. So my question is, has anyone had this problem, and does anyone know how to fix it. If it comes down to this, which I hope it wont, I could just buy new O-rings for each big blast I buy, but I wouldn't know where to get those either. Advice will be most welcome, and will help to spread the spirit of nerf.

Ok, so I am currently in the procces of creating an angel breach, but the pin that attaches the stock barrel of the longshot to the bold slead seems to be glued, or otherwise lodged in there so tight that I can't budge it. I can also see some kind of resedue around the seams of the pin and the slead. Has anyone else had the problem, or am I screwed?
