Super Bolt Update with PICS (you guys are driving me nuts)

[AGD]

All of AO,

Ok you guys are pounding me left and right about this thing so here are the pics. On the left is a bolt that went through about three tournaments, the middle is a brand new one, on the right is the bolt without the Delrin sleeve. As you can see there is a wear problem so you have to replace the sleeve periodically. We are working on this and other interelated stuff so please stand by.

Thanks

is the wear problem atributed to the super tight bore/step bore barrels most tournament players use?

The one that went through the tournaments, is that a foamie on it?

[Monsta]

ouch ....talk about used and abused

Tom when you are saying the delrin sleeve needs to be replaced. Do you mean it needs replaced because its looks chewed up, like the on it the PIC, or because of some other reason like blowback. I don't think that the bolt sleeve would need replacing as much as you are thinking it will need if its just for looks.

I'd guess that it gets worn out by rubbing up against the spring thousands of times. Lots of relatively sharp edges on that spring, not to mention that the spring metal is a lot harder than the delrin.

I would venture a guess that it has nothing to do with cosmetics, just tolerances...

It can get a lot more worn out before it starts really causing problems. I am just afraid some father will call me complaining his son just bought the thing with his last dollar and now it's falling apart. See what I mean?

wow

how much? how many times do you have to repliace it? and can I order some with my intelliframe (when you make the matte black ones)

Tom,

Have you ever considered using something other than delrin?

How about Nylatron (I think its called) it's supposed to be more durable than delrin.

I think there are a few cocker bolts around that are made out of Nylatron now instead of delrin.

I think cast iron is the answer

I remember fondly the days of shooting the PMI-3 Piranhas and the satisfying thump the hammer made inside the marker. You knew you were firing every time you pulled the trigger. :)

The "nose" of the bolt on the right looks different. What's the reasoning? Will it be a foamie bolt also?

Not sure if this is possible or was considered already - If it is the friction/contact between the delrin and the bolt spring, can the bolt spring be made in a tubular shape, like a...a coiled snake, so it wouldn't have the "edges" of the current bolt spring?

Dunno how feasible it'd be, but how about a thin metal jacket on the outside of the delrin sleeve? It'd serve as a 'sacrificial' wear surface while still having most of the weight advantage of the 'pure' delrin sleeve? Sort of like an aluminum honeycomb panel. Strong but light.

Or...instead of a metal sleeve around the delrin, have a few metal rails along the length of the bolt to take the wear and tear? Same advantage of a metal sleeve, but it'd keep even more of the weight savings of the pure delrin sleeve. It'd kinda look like one of those 'Crossfire' barrels. Except with delrin inbetween the rails of course. :)

Though I imagine that that either idea might have some tough manufacturing problems.

RiceRocket and Gunga beat me to it. I was thinking of the same thing... rounded spring and/or some kind of metal cover over the delrin sleeve. Are you guys reading my mind or what?

Tom, would this be possible?
