a few kind of random questions

i have a few random questions

what is the exact on/off pin length and assembly for a 68 classic lvl 10 mag with an e-lcd trigger frame? what would keep a nitro tank from passing a hydro test? how often do they not pass? all answers are greatly appreciated

The link to Automag tolerances is here As far as finding the exact lin length for a eLCD grip frame, good luck. I think the best you can do is to buy a Centerflag pin and go from there. I can tell you that when I did a side by side comparsion I found: stock pin length < CenterFlag pin length < eLCD pin length. I no longer have the eLCD grip frame or I'd measure it for you.

Its been a while, but if I remember correctly from Scuba diving classes, hydrostatic testing has 2 parts. 1. Visual inspection of the bottle's interior and exterior. Things like rust or visible damage can cause the bottle to fail this part. 2. The tank is overfilled by 10% in a controlled environment. If it doesn't rupture it passes. HTH.

Wow, that's quite an interesting tid bit of information. Would any little tiny scruffs stop a tank from passing hydro, or is it just a bit bigger things?

No, small scratches wouldn't fail a tank. if, for example, say you could see the carbon fibers starting to seperate or the tank took an obvious drop and a normally round edge was cracked or damaged... basically anything that might cause the tank to crack/stress/fail under pressure.

I think the part about visable damage is most for steel/aluminum scuba tanks. I'm by no means an expert, so... take it for what its worth.

also, the threads must be good.

it's not just the outside that counts.
