Concern about white Delrin for muzzle

  • maybe a hot water soak, but after salt crystalizes it takes more than just cold or mild warm water to break it down. this is why it is really pointless to flush your boat motor after it has cooled down. Jeff may have allready fixed problem when he adjusted tollerances towards outside portion of delrin muzzle. only real way to keep salt out is to use some sort or sealer/grease, especially on a porous material like delrin.


    ALSO: the portion of the delrin which spike is installed is the most porous part of the stock which was used. its called centerline porosity and its a huge problem with some polymer acetals like delrin


    ALSO: Clears are more porous than blacks because the fillers used to dye the material bond to the polymers filling voids during the cooling process.

  • you are a wealth of knowledge...thanks a lot...I think a small pucket in the shower is the key...fill it with hot water as I shower and rest the gun, muzzle down for a soak after each dive.

  • or take tin man up on his offer for a new black muzzle and have the outer tollerance opened up. but hot water is definatly good for washing anything that touches salt water.


    cant beat salt water but man it can screw up man made shit.

  • Lunkerbuster, not all stainless is impervious to rusting, you can see the stains in the crack vector.
    That crack will continue to propagate and a Bull shark with some back....( ''as in my baby's got back"):D
    will be using the shark probe to pick her teeth. I would get another muzzle and seal in the spike with 3M 5200.
    Washing in the shower and soaking in the shower is too much like work and only address the salt crystals if left over night like a bucket of water and overnight soak frees a frozen prop to shaft.

  • thanks guys...so you know...Jeff has already replaced the first muzzle in this thread with an additional white one that is holding up very well.. there is evidence that it wants to start doing the same thing again so I think I will do a nice long soak, then seal it up per the advice.


    a danke
