"The trigger is a metal L-bracket which operates on a simple pivot system, it links with the catch system via a cut-out slot in the trigger handle (the slot acts as a fulcrum point for the trigger)"
Simple physics... when the trigger is pulled, the L-bracket pivots at the cut-out slot which causes the trigger catch push bolt to move in a upwards angle to push up the catch, thereby releasing the plunger rod and firing the blaster.
Hmm, the design is direct plunger, yes? Your main spring is in front of the trigger plate, unlike normal Nerf springs which tend to be behind the trigger plate. Does it make a difference in reliability or weight distribution?
Strikes me that the Nerf setup can be more compact, in that it reuses some of the structure necessary for the pull rod, and that you can shorten the length of the body/ barrel. The key question is what you intend to do with the whole SGN-R series -- are they going cover the big capacity long rifles to compact blasters? If so having a compact and powerful chamber/ plunger system makes sense.
If you are looking to incorporate electronics into the system at some point, I found some very interesting and powerful actuators for small scale work.. was thinking of using some of those for some Nerf applications. For one, some of those can act as trigger plate actuators, mechanically simplifying the trigger mechanism as well as reducing the trigger pull.
Incidentally, any intent to work out a auto-feeding mechanism? Nerf's clip system is ok but hi-cap clips are hard to come by (18+ rounds is fetching ridiculous amounts on ebay..). If you can come up with some sort of hi-cap system, especially if compatible, it'll be great.
Lastly -- I'm in SG too, but to be honest I'm finding it hard to source for the material that you have obtained. Plumbing supply and hardware (like the latches you used for the Stampede) isn't really that common around... probably looking in the wrong places. Do you have a source I can go to?
As mentioned in my R Series blaster overview, my catch ring and trigger mechanism is designed for both simplicity and durability.
There are many other ways to make catch and trigger designs and it'll just depend on how simple or how complicated you want it to be.
I have plenty more designs and variations that are currently in development and testing, all the way from large scale blasters to small compact blasters, along with some unique blasters too... and they all look and work completely differently from the R Series designs.
One main factor is common amongst all the designs though: More air volume = More power. Even if smaller air volumes are matched with stronger springs and faster plungers, they still have limits to their power, so that's a build factor to consider.
I have also tested using mini electronic and hydraulic actuators for triggers too but they add way too much unnecessary parts into the trigger action, which can easily be achieved with a simple L-bracket and return spring.
As you can see, the objective here with such blaster designs is simplicity and effectiveness so that they can be easily built and maintained, no point making things over-complicated.
As for ammo management, most modders use the existing RSCB clip or Hopper clip designs which allow such blasters to have multiple ammo capacity, though each of those designs have their pros and cons (mainly dead space in the clips which waste air pressure).
I am currently testing a N-Strike clip compatible design with 100% air seal which is close to being completed, that will enable a higher rate of fire while still offering maximum power efficiency, so stay tuned for that.
Since you have not worked on any DIY blaster designs yet, i'd recommend you to just build the basic designs and get them to work, then once you have the experience, start incorporating your ideas into the designs to see if they are worth the time and effort (and actual effectiveness) to do.
Check at the NerfSG forum, all the links on where to get modding materials locally have already been posted and discussed there.
As i mentioned in my earlier comment to you at my SG Nerf site, you will have to be familiar with the SNAP blaster design before building the R-Series blasters, read up on the SNAP guides at the NerfHaven forum beforehand.
thanks, don't you think that it would be better to have a whider plunger tube that is shorter so it can hold the asme or more amount of air but not be so long.
Sure, DIY blaster builders can customize their blasters to any plunger diameter and length they prefer.
Part of the SGN-R3L overview was a demonstration on how long the plunger and draw can be, while yet still being possible to use. It's designed to be modular so the plunger size and length can be changed easily.
As mentioned in my previous comments, i have many variants of the R-Series blasters with different plunger diameters and lengths, one example is the SGN-R55L, that one has both larger diameter and extended length for very high air volume. I have many shorter plunger versions too but prefer getting maximum power out of my blasters... it helps that i'm tall enough to handle extended plunger lengths too. :)
could you please make a cut out? what i men is, to show the actual real life internals of the blaster, rather than just showing a photoshop, or watever it is.
If you are still not clear about it (after looking at the "exploded" view and cut-away schematics), it means you still don't understand the basics of how foam dart blasters work.
You should work on modding Nerf blasters first and get familiar with their trigger mechanisms before attempting this DIY design.
I already got the idea, the small problem was that i hadn't modded in one year and i'm a bit fuzzy. I et the idead now, and it looks like it's easy to do.
Okay, maybe this is something really simple that I'm just not getting, but how are the catch spring return bolt and trigger return spring bolt attached to the PVC? I don't see any space for the nut.
i still dont get it how does the trigger push the nail our of the notch?

could you put up some instructions on making it and list all the materials and tools needed.
ReplyDeletehow far does it shoot.

what kind of spring do you sugest using
ReplyDeletetombo19991,
ReplyDeleteJust design your blasters, then source for aftermarket industrial springs which fit your blasters dimensions.
thanks,

yo sg i just wanted to know since ive only modded for 5 years it may sound dumb but are you selling these?
ReplyDeleteDantaur,
ReplyDeleteI'm not selling these items, that's why i post up the guides so that people can refer to the design and build them on their own.
could you please make a cut out? what i men is, to show the actual real life internals of the blaster, rather than just showing a photoshop, or watever it is.
ReplyDeleteSteve,
ReplyDeleteYou can see the "exploded" view of the parts in the SGN-R3L overview:

Thanks for the help :)
what did you use to draw this?
ReplyDeletetyler,
ReplyDeleteI used excel to create the colored blocks and lines, did a screen capture, then rendered the rest of it in photoshop. :)
Okay, maybe this is something really simple that I'm just not getting, but how are the catch spring return bolt and trigger return spring bolt attached to the PVC? I don't see any space for the nut.
ReplyDeleteBillPosters,
DeleteOkay, that part is partially screwed into the PVC T-joint, so that the small spring pushes the trigger return back to position after use.
If you refer to the photos of the entire blaster, you will see the trigger is sort of pushed up against the T-joint by the trigger return spring.
