absolutely!

well not really, cuz who else can say they have a closed bolt spyder? um. no one really, maybey deadlywind, but never seen it. all that stuff just gets rid of the cruddy spring blowback function of a spyder

hehe
good answer

i like it even more now that you said that

[SIGSays]

hey man... that is pretty tight.. but i think it was a waste of money.. lol

if you look at the back, where the beaver tail is, you will see the ram is mounted to the rear......no backblock. i tottaly auto-cocks internally. think blazer.

oh ok i just figured out what you meant
hehe

well I wouldn't say no-one......there are a few spyder cockers out there.......

the rail system is slightly different........it is basically a ram actuated bolt. the hammer is still blown back, just like a stock spyder. the bolt is controlled by the 3-way. Mine is actually a true auto-cocking system. I had to have a custom valve made for it that has NO blowback to it. if you fire the gun without the bolt in it, the hammer just smacks the valve and stops......no blowing back.

That's awesome, SpyderCockers are pretty rare too.

[sneakyhacker420]

kind of like an impulse or cocker valve?

[xen_100]

it is basically a cocker valve that is dimensioned to fit into a spyder.

more picts!

you can see the way the bolt is slotted to cock the hammer in the 5th pict (kinda)

I think that is amazing. I really think its cool.. and the bo-bo ghetto superstar look makes it even better!

[coolcatpete]

So it looks cool and all but does it work? And how well does it shoot well? And last did it cost alot or not?

[xen_100]

it works really well.......I can pull about 8-10 BPS before I start to short stroke it.

I haven't shot it with paint yet, hopefully this weekend I will go play. I will let ya know how that goes.

well I got the spyder from my brother for free (a compact is about $50 new right now) and I spent $100 on the pnuematics. the barrel is from my other spyder, so I dont really count that...........so I guess $100.

Xen- interesting design. you might consider mounting the 4-way in front of the trigger frame (see pic).. its more out of the way and inline with the trigger which should prevent it from leaking when moved. Also, use a larger diameter ram (3/8" as opposed to the miniram).. that should give you more pull back on the hammer while minimizing forward pressure on the bolt. its reverse concept from a cocker..

this is a unit I sent to Aardvark for thier manufacturing consideration:

[xen_100]

I thought about it, but I wanted to put it somewhere nobody has before, plus with the pnuematics in the rear, it makes for only one long hose instead of two.

as for the ram, it works great. a larger diameter ram wont give you any more pull than a smaller one. if the same amount of work is being done, then it is the same (even if the smaller piston has to operate at a higher pressure. the same amount of force is being placed on the ram shaft.)

also, theoretically, a smaller ram would be able to cycle faster. higher pressure, but less volume of air to evacuate for each cycle. (also the higher pressure differential would tend to want to equalize faster too )
