[coolcockerguy]

hey does anyone have a pic of the delrin aka bolt for a autococker?

thanks splatter but theres not a pic of the delrin lightning there.

Delrin = not the best material for LP

Lighting Bolt = best used in LP markers


Anyone see a bit of a problem in theoretics here?





I didn't even know there were making a Delrin Lightning Bolt.... I have a regular lighting bolt for a pre-99 STO (hint to those people who want a bad arse bolt)

Why isn't delrin good for LP? Just wondering, cause I have a delrin bolt in my (sort-of) LP gun... :confused: Seems to work pretty good. :)

[DasBaldDog]

I didn't say it isn't good. I say it's not the best..... try reading first people...

The material composition of delrin adds a few small problems to the condition of sealing air.

You can't oil most delrin because it will cause swelling.

Secondly, delrin can be EASILY abrased so delrin part manufactures make each delrin part a micron smaller than it should be to prevent rubbing.

Okay, not flaming here, just asking questions... :)

How would the composition of a wear-resistant, dimensionally stable, and chemically resistant acetal homopolymer affect it's ability to seal air? Delrin is non dynamic; even at great pressures, the material will not deform, and is resistant to fair extremes of heat and cold without shrinkage or expansion.

You can oil most delrin, unless pball manufacturers are making their stuff out of seriously substandard material; delrin, amongst other thermoplastics, is highly wear resistant, and good for +/-.001 inch; I color my by boiling them in dye-- a huge increase in diameter would be .0015. I've never seen .002.

Lastly, I think bolt manufacturers make delrin bolts undersized because the quality control on building the guns themselves isn't that good-- the tolerances on Spyder bodies is a joke; you simply can't make one bolt to fit all guns. But they try to anyway.

I guess my personal beef is that Delrin has to take the rap for poor manufacturing. Are we better off with aluminum? ;)

[DasBaldDog]

Not better off with aluminum at all.

It's just that in my expierence and as with a few industry reports I've seen, show that delrin has problems sealing perfectly (not letting one single molecule of air out) in lower pressures.

Delrin doesn't swell with most oils, use a silicone lube if you are at all concerned about that.

Also, there is no difference between a delrin bolt and a metal bolt for LP or HP.

On the point of manufacturing, I think most major problems are due to either poor quality or other unforseen factors with the marker like wear. I've seen a cocker so old the bolt was wearing a groove into the side of the bolt housing. Try fitting an aftermarket bolt into that!

[DasBaldDog]

Yes there are MANY differences in the performance in a delrin bolt in LP and HP.

[Lord Delta]

So if delrin "is not the best material for LP" is it ok/good for HP?
And how low is low?

[DasBaldDog]

It's about the best for any pressure above about 250 psi.
