I've currently got mine hooked up to 12 volts, and has an additional spring (I think it's a chain blazer?). Now mine hase the problem of getting darts stuck in the dart tooth. The motor gear line up seems to be off, cause I think the plunger has started releasing as the whole chamber moves backwards..... has anyone else had this problem?

Yes, I have had the same problem, the way to fix it is to increase the return spring on the piece below the catch, (if you have replaced the catch spring.)

No, you do not. You can just use the templates as they are.

Thanks buddy

Hey guys I'm about to start my plusbow, and I am wondering. I am in Australia and the materials over here are different and scarce, I don't know if i can get the parts for the plunger tube and the plunger, but i can do everything else, also with the Rev2 templates, do you have to scale any parts up? They look rather small.

Im working on a homemade but it requires about 7" of spring. The spring is 11" so it needs to be cut down. Anyone have advice on the best way to do this? Simply cutting it with a dremel?

If you have a pair of wire cutting pliers they should do the job perfectly, you can also use long-nosed pliers to bend of the ends of the springs.

I recently tried to make a simple SNAP with a standard clothespin trigger using 3" PVC as the plunger tube. For whatever reason, once it was all assembled, the Plunger head never got a seal, and always had friction, so that even with my [k25] spring it moved slowly. Is there something wrong with 3" PVC, or is it simply something that I'm doing wrong? I was using a custom plunger head made of wood with a groove for the O-ring. It was turned on a lathe. So, any ideas?

I have had the same kind of problem with my homemades. Sometimes it depends on what material you make the plunger head out of. If you want you could try the same method of plunger head with polycarbonate , this will make it even stronger, and also you might want a spring stronger than a [k25], i would suggest a k12 with a [k26] nested inside. Good luck.
