I've seen someone post a bbumb with the pump replacement piping acting as a tank expansion so I think it should work. I feel more comfortable with rubber hose and hose clamps than barbs and adhesives, so that's why I ask.

    It would be interesting to see some results...

    I'd still be more confident from a safety perspective with replacement pvc air tanks and epoxy adhesive or similar...

    Sorry mate, but Goop is completely different to any of the silicone products (sikaflex, silastic etc).
    I've searched for quite some time, and can't find a supplier within Australia. Though, I have seen it for sale on ebay, though it is quite expensive with postage from OS.

    Cheers,

    Trial and error basically. When the range stops increasing, then it's too much... haha.

    Seriously though, I had my first BBLS opened and closed about 40 times trying to get the seal perfect... lol

    I personally use 1.5' stefans but 1.25' seem to work much better. Also if you are going to use a hopper, I like to turn it into a chopper. With a chopper you can only use 1.25' so hoppers are better in some ways.

    Although thy are old, they only go for a couple of dollars more than standard NF's. I've seen them go for around $12-15.

    Big Salvo

    Post  Zandor on Wed Jan 25, 2012 11:24 am

    Hey guys, 2 quick questions about the Big Salvo:

    1. I pulled it apart recently to try an integration mod. I've noticed the back of all the air tanks look like they have stress marks around where the tubing enters the rear of the tank. I haven't done any mods except for pull out the AR's with needle-nose pliers ... anyone know what this means? Is it possible that the tanks might "explode" if I over-pressure them, even though I haven't plugged it? (I usually do about 8-12 pumps max if that counts for anything)

    Here's a pic to show what I mean:



    2. One of my tanks leaks air if I don't pump it up fast enough. Because of this if I pump too slow, NONE of the tanks fill up. If I pump quickly then it's no problem... but I worry that this one tank may cause problems for the rest of the system... I looked up on Nerf Haven about clearing out any dust / plastic particles that may be choking up the seal in the tank, but other than that I'm stumped.

    Anyone got some answers for this puzzle? (And yes I'll be buying a couple more Salvo's as a backup plan XD)

    I know It sounds like a silly thing to ask but are your batteries any good, and do you have the polarity right.

    All I can recommend would be to try and improve the pump seal, whether it be a new O-ring, or just some teflon tape under the existing O-ring.

    The two different types of batteries might be causing a problem, try brand new ones of the same brand. Also make sure you have everything wired up properly *captain obvious* such as the connections, maybe one has come apart?

    I had the same problem myself so I just ended up doing this instead ...



    Two small alligator clips with hook up wire and alligator clips on the other end hooked up to my 12v S.L.A.B.
    I had to removed the battery tray off the backing plate piece but the 12v fits nice and snug sideways in the compartment.
    Then you just screw on the back plate on. DONE!

    Of course what you could do is ...
    Get some hard foam and cut out some battery slots and slide that into the back instead (To stop your 9v's moving around.)
    Or get some 9v battery holders?!
    Much easier then messing around with the battery tray trying to get a good contact.
    To get the clips on you will need a long pair of needle Needle-nose pliers and some patients lol

    But the end result is nice and clean with no cut and completely reversible.

    Here is what my 12v installed looks like ...

    If you don't have a Jaycar maybe you have a local electronic type store.

    Here are the clips i used, they a pretty cheap as you can see.

    I doubt 9V transistor batterys have the mAh to run a Stampede even in series. The reason they may have got hot is if you left the blaster in a firable state ( Clip in, jam door closed, safety off) after pulling the trigger it would have still been trying to complete the cycle.

    Another Big Salvo question

    Post  Zandor on Thu Jan 26, 2012 3:12 am

    One more annoying question: for my Big Salvo to fire stock / modified stock / blue foam darts, should I use PETG, Brass, or something else?

    I've done some reading and it seems like PETG is often the case for air-tank blasters like the Big Salvos... but the tiny bit of PETG I have tested with doesn't seem to provide a 'tighter' fit like 17/32 brass does. BUT! Is it a good / bad thing to have tighter/looser dart fit in this scenario...?

    (I realise I may just have to try it out and see which works best... but I'd like to hear some advice before I go out and buy lots of materials and a back up Big Salvo, potentially wasting money @_@)

    Generally a slightly loose fit like you get with PETG (using blue foam) is good for air blasters and high air-output blasters

    The best barrel is the barrel which creates a perfect seal around the dart, but not tight enough to cause friction.

    Today I'm going to go get some 13mm fbr, I tried looking it up on the Clark rubber site but had no result, so can someone confirm it for me. Can I get 13mm fbr at Clark rubber? If anyone can also tell me how it comes (length, colour) and cost.

    It comes in white and you buy it per meter it's like 85cents or 1.85 can't remember, Clark rubber definitely sell it, just call befor you go.

    A bunch of odd questions relating to an upcoming homemade of mine that is presently in the concept stage...

    What's the ideal barrel fit for a high-powered springer?

    How does range increase proportionately to plunger size?

    How does spring load increase proportionately to spring size, if it increases at all?

    What are the merits and demerits of a using larger-than-standard custom darts?

    What's a good, solid form of pipe to make parts out of? (i.e. shoulder stocks, plungers, etc.)

    What's the ideal barrel length for a high-powered springer with a plunger volume of 400 cubic centimetres? (We're currently working with 75 cm).

    Where does one acquire truly ridiculous amounts of polycarbonate, and what is the optimal tool for cutting polycarbonate?

    If anyone has the know-how to work all this out, I would greatly appreciate it. Should I get satisfactory answers and decide to go ahead with the project, you should all get to see what we're working on in roughly twelve months.

    Pros: You could make a more solid dart with 15mm fbr

    cons: you cant fire darts you pick up off the ground, cant use nerf clips, bigger pvc required for hoppers, choopers and inlines.


    Reaper wrote:

    Obviously the bigger the better, but you would need a sutible barrel, somthing with 300cc needs 1foot or more

    Bunnings/m10 or a direct supplier, and a router would be the best tool, atlest it is for me


    Though i could be completely wrong about everything im relatively new to nerf and this is the information ive gatherd over the past few months of research for my on home mades
