    Pleagh Longshot

    Post  pleagh on Fri Jan 20, 2012 2:29 pm

    Doing a rebuild of my longshot.
    Keeping a build log for ideas and opinions.
    First step:
    Get new stuff, Oznerfnerd kit was a great buy.
    Step 2:
    pull it apart


    My aim is to make it bulletproof(pardon the pun)
    So i cut up some coat hanger to put in the plunger and used some 3day Araldite to keep it in place.


    Wait 3 days to dry and repeat on the other side. In the mean time try reinforce the grip
    Any and all ideas welcome.
    Cheers

    I was looking at this other night with my longshot.
    I wasn't sure if it was needed or not.
    But my idea was to use carbon fiber rods as they are not as heavy.

    Seriously guys, not wanting to rain on your parade, but have you ever seen a longshot plunger rod break where your reinforcement is??

    I'm not exactly a seasoned veteran, but I've definitely destroyed my fair share of LS internals, and to date, I'm fairly certain that I've tested the biggest spring load on here (oxy??)

    You need to focus on reinforcing where the plunger head connects to the rod...

    Cheers,

    The main thing in 'reinforcing' a blaster in general is where the stress points are. makeitgo has a very good explanation of this concept.



    Skip to 6:40. He explains the 'pressure points' in a triple shot. Mainly, where the spring is putting pressure on your parts as you upgrade your spring load =).

    Bring the rain! ( :
    I haven't as of yet and not looking forward too it.
    I do see you're point about the plunger head and that did come to my mind first for sure.
    Just out of interest sake, has anyone had the rod break due to higher spring loads? If not then i won't bother with it.

    It's not the rod that break. It's the screw port where the plunger head connects to the rod is where it breaks. Oxymoron has said 16kg will break your plunger rod eventually without reinforcement. I dont' see the point having so much spring load if you cant' prime it quickly and efficiently.

    Using new LS internals, I somehow managed to snap the screw port of my plunger head using just a 13kg spring. This was a brand new set of internals to replace the previous busted one.
    So far I don't think any one's come up with a way of reinforcing this part of the plunger rod (without entire replacement that is).

    Yeh,

    I've had approximately 32kg spring load, maybe a bit more - stock, SSSpring and oxy spring. Only got 2 shots out of it, and the boltsled exploded.

    I've had a few plunger heads come off with SSSpring/BTV2 and stock spring, but never had the actual plunger rod even weaken, let alone break.

    Cheers,

    Bolt sled (parts from Oznerfnerd)



    Trigger, saw this from Cxizent



    Plunger: was covered in epoxy putty with small bits of metal (from the bulldog clips) so the 'L' shape rests on the plunger head, sorry i didn't get a pic of that part. Springs are Oznerfnerd and stock



    I now have a plan for the grip as well, fill with epoxy putty and have a piece of pipe stuck in one side and a hole on the other so the pipe can fit in it. ill post pics when i get to it.

    Hey mate,

    Nice to see your work in progress, especially with my kit in it.

    Just wondering...

    Do you need such a heavy spring load?

    If you're not using a brass breach, is there going to be an advantage that's worth losing ease of priming over?

    It depends what it's being used for.

    If like Clunk for example, you are going for smaller numbers of long distance shots, fair enough (you'll need a brass breach).

    If you are wanting to use it in wars, I'd stick with my spring only or it'll be a pain in the arse to prime all day.

    That spring is designed to give maximum gain from a standard breach, and a solid performance with a brass breach.

    It's quite firm to prime by itself.

    Anyway, nice mod!

    You've certainly got the reinforcements going on.

    Cheers,

    Haha - my commission's are only lower ROF for the kids, and maybe some of the Mexican's.

    Maybe I should include a free gym membership with my LongShot's...

    Clunk anything V2 is automatically a gym at every war. I've got legit bicep burn in my right arm after a couple hundred hurried primes.

    The stock spring was not going into anything else, I figure it will do more good being in there then not.
    Priming should not be to bad, longshots don't have slam fire so RoF can only be so fast anyway.
    Brass breach will be something I look at when I get some more tools (and better at modding).

    Anyways next update:
    More bolt sled stuff, used some allen keys as they fit in perfectly.

    Um... yeh... well while having the stock spring in there won't do a great deal for range without a brass breech, it is adding extra stress on the connection between the plunger head and plunger rod. I mean, all my commission's have the 2 springs, but that's the gamble you take for wanting to maximise a BBLS. If you're just running stock breech, the smart money would be on omitting the stock spring until you brass breech it, then epoxy on the plunger head to the rod.

    Cheers,

    Does the bolt sled still fit in the shell and move backwards and forwards?
    That looks pretty close to the rail guide ...

    Hey that's SWEET with the allen key!

    From this day forward it should be known as "Pleagh's allen key mod".

    It's fair enough.

    That's tempered steel, by the way, and should add some serious rigidity to the thing.

    Just a thought on these springs, I had a look at my LS stock spring against Oznernerd's spring and as you can see by the pictures above there not compatible. The stock spring is wound clockwise, Oznrfnerd's spring is wound anti-clockwise. Which I assume would normally not be a problem but these two springs nest quite firmly and rub together, The friction between the springs when released is going to absorb any extra energy gain you had from adding the stock spring. Not to mention filling your plunger tube with junk from the springs rubbing together. However I'm the first to admit I'm no expert, Please correct me if I'm wrong. But it's an issue I'll definitely avoid either way. D.

    Short answer is no.
    But you can fix it very easy, grind/sand off the sharp edge on the top guide rail to a ramp
    You (I didn't try to be honest) cant grind down the allen key but some epoxy on the end to take off the sharp edge helps too

    Oh lucky you could fix it else that would have sucked big time. : )
    But still a nice reinforcement.
