You could try here?

I don't own a x-bow so I can't speak from experience but you could try putting the metal rod the lenght of the plunger to add support.

All the suggestions I've seen to date have involved cutting notches in the side supports so that you can epoxy thin metal rods down the side grooves.

I'm going the route of replacing the plunger shaft entirely in my (eventually) forthcoming mod. I'll simply get a square rod of some durable material, cut a notch for the catch, and thread both ends for attaching the head/handle.

Steel reenforcement is definitely the way to go, and I'd have to agree with everyone else when I say steel rods or heavy gauge wire is the best route to go. I used heavy duty coathanger wire on mine (doubled up) with a generous application of JB weld epoxy. I like to use shit around the house, and I didn't want to waste gas driving into town to buy heavier gauge wire.

The only other thing I'd have to say is that I have to question why Rawray didn't reenforce the entire length of the plunger shaft? It's a given that the most common site of breakage is at the catch, but when not spend an extra few minutes and do the whole length? Shit happens in wars when you're running and diving, and it's concievable that a branch or a table leg or chair arm or something could hit the plunger shaft from the side and break it at and odd place, were it not reenforced. I'd have to say it's preferential to do a little preventive maintainance now than to have to deal with a weird break later.

The added weight might be a factor. The heavier you make the back of the piston the more resistance it could have against compressing air, resulting in sub-par performance but superior durability.

Yeah, that's definitely a factor. I'm planning either silicon impregnated nylon or titanium for my replacement xbow plunger shaft. Obviously the nylon is cheaper but titanium would be so cool.

Oh my god titanium would kick ass. I'm desperately trying to fix and old nightfinder plunger. What happened is that I stripped the inside of the plunder and then glued the screw and end in but I was so dumb I forgot to put the spring on. Then I was trying to get it apart and I just ripped broke the plastic! I' still mad at myself and this was like a month ago! :rolleyes:

Titanium?? thats goin a bit overboard costwise for a nerf weapon. aluminum would be a good choice, light, cheap, strong, and easy to work with.

Ti would be pretty cool. but if you were gonna do that, you should really recase it too.

It's going a lot overboard strength-wise, but the cost shouldn't be that big a deal. I'm planning on having the sickest crossbow ever and that isn't going to happen without a little green. At any rate, I think I can source it for about $10-15.

If you have a cheap supply like that, I suggest taking orders. I, for one, would be interested in some new plunger rods. Titanium... why not?
