Here Are some pictures of my JSPB Style homemades based off the design of the "Boost".
Here You can see the double valve trigger mechanism. ( and for all the noobs reading this that is so you can keep shooting without having to pump each shot...)
A different angle... Also I can attach a inline clip or an arrow launcher.
the arrow attachment.
with the inline clip. Please comment!

I've never understood how inline clips work, but this looks very functional and simple. Nice work. What ranges do you get with it?
Probably dead by now, or something.

The inline clip is usually a piece of thin wall PVC that holds the darts in loose. There is a tight barrel coupled to it on the end. When the gun is fired, air goes around the darts in the loose clip but fires the dart in the tight barrel. Loading varies: my friend made one that air pressure alone forced the next dart into the barrel and all he had to do was cock and fire. The ones I make have to be tilted downward for the next dart to advance.I've never understood how inline clips work, but this looks very functional and simple. Nice work.

Think that piece is beyond repair? Think again!

Hey, would it be possible to put an incline clip on a gun like the crossbow?
Yep, but It'll probably be best used on a air gun. I haven't done that much experimenting with it though. You should definetly try it Ice if you have some extra couplers hanging around. They are really simple to make.

Nice work, though. I'm sure with a paintjob 3D would be proud of it.
One piece of advice I would give is, in terms of comfort, it's probably best to make a stock out of PVC as well. I realize none of the guns here have them, per se, but you can achieve it relatively easily. Instead of putting an endcap on the bottom half, make it a t-splitter and cap both ends of that ( with some piping exposed if you choose to make it longer ).

Also, Nice job on the homemade. 1 question though, whats holding the PVC together?

What kind of valves were they Rambo?

3DBBQ uses ball valves as well, but they are much easier to turn and they're more of a trigger shape.

It says Ball Valve ST. Does that mean street ball vales?
I've no idea, to be honest, but I doubt ST stands for street... I've never heard of a particular kind of ball valves referred to as such either.

The ball valves that 3DBBQ uses are similar to the metal ball valves at most hardware stores.
Really? I've checked my Ace, Lowes, Home Depot and a few other ones that I can't remember the names of and I've never seen them.

I disagree; it would be less than optimal with a Titan. The traditional couplered barrel would work much better due to the fact that the titan doesn't have a reserve tank as well as the firing tank. With an inline clip, each shot would have to be primed by pumping up the main tank in the Titan, compared to simply flipping the rear valve to refill the firing tank on a JSPB. You'd still have significant priming time while reducing the gun's power because of the inline clip's dead space.It should work great with a titan.
Has anyone tried to contact 3DBBQ about shipping over some of those ball valves?

They aren't the exact same, but they are the closest we can get here. Similar open times, I think.Really? I've checked my Ace, Lowes, Home Depot and a few other ones that I can't remember the names of and I've never seen them.

I keep meaning to try one on my SM1.5K, but I never get around to it...soon.

As far as inlines: with an inline on my SNAP, range decreases by about 25% (90' down to about 60-70' or so). Range decreases, but the ROF increase more than makes up for it. (i.e. my next project is a rebuild of the SNAP-4). I would think that an inline would work quite well on a crossbow. After all, Frost Vectron got good results with one on a Razorbeast.
Tight dart fit doesn't matter in an inline, so long as the barrel attachment tapers into the tight area. So long as the dart can seat a little bit into the barrel, it'll fire.

I use a bullpup type inline magazine on the crossbow for indoor or CQB type battles. Less the bungee of course.

If the clip portion is schd. 40 PVC, switch over to thinwal. That should give you the clearance you need, while letting you keep the same fittings.The only problem is my inline clip is working like CRAP! I think some one said this before but the "clip" part is way too tight and the darts don't slide at all... any I deas? ( other than that it's working great!)
Oh, and to be accurate, that's an RSCB clip, rather than an inline.

Yeah whatever .... But I will try the thin wall one I can get to the Hardware store.Thnx!If the clip portion is schd. 40 PVC, switch over to thinwal.
