Oh ok, I looked up the SNAP and I would try one, but my fabrication skills aren't up to snuff.
They're really quite easy to make - don't be intimidated! If you decide to build one, I would recommend trying
Rork's SNAPbow Mk V, which is the current state of the art in pull-back SNAPs.
The other suggestions in this thread are good, but building a homemade will teach you a lot about modding. Not to mention that SNAPs are
extremely effective blasters, with ranges easily clearing 100ft.
Can someone with clip fabbing experience tell me what diameter and types of pvc are used in this image
That's what we call and RSCB clip. Almost all the fittings and pipes you see are 1/2" sch40 PVC (which allows darts to freely fall through). The elbow section is called an "elbow", and the T section is called a "tee" (duuuurrr). The barrel section (sticking forward) will be made of CPVC, or some other material in which darts have a tight fit. If you go the route of a Big Blast or a SNAP, it is a very good idea to use a clip system like this. Very high-volume blasters (such as bow designs mentioned here) will work well with an RSCB as well.
Lately, there has been a mass conversion of sorts to a more modern clip system: the
hopper clip. These perform better than RSCB clips, and have a number of other advantages as well. They do, however, require a special PVC fitting (the wye) which is only easily attainable off the internet. I would say: stick with an RSCB for now, just as a starter clip system.
Ultimately, if you decide to build a SNAP, and then attach a hopper clip to it, you will have a very powerful homemade than can compete with nearly anything on the modern field.
