Question on vintage Crosman revolvers

In my airgun collection I have 5 vintage Crosman revolvers, 2 peacemakers, 2 single action 6's and a Hahn. I have not fired any of them because, well, they don't work. I'm sure they all need resealing but I can't even get to that point to know. Trouble is, with all 5 of them I cannot get the cylinders to pierce. I can turn the little thumb tightening wheel to the point I cannot tighten the screw with my thumb anymore and the cylinders still aren't pierced. I did get one finally tightened enough to where it pierced but all the gas leaked out. Likely because of bad seals but I couldn't tighten the screw anymore to see if it would stop leaking. So my question is, when the cylinders won't pierce, is it because the piercing pin has worn to short or the point maybe mushroomed? If so, are the piercing pins obtainable or are they throw away guns as far as actual use?
 
Do you have the Co2 cylinder facing the right way?
I use to oil the threads on the piercer. and a gob of vasoline where the nipple got pierced. Could be a brand name thing where Crossman cylinders were the preferred.
 
Yes, the cylinders are the right way. Yes, I oil the tip of the cylinder. I have tried Crosman cylinders. I have many other air pistols and they don't require brute force like these revolvers to pierce the cylinders. I doubt they would even pierce with pliers which I'm not going to do. That's why I'm wondering if the piercing pins get worn on these. I wouldn't be surprised if they weren't over tightened with brute force by previous owners.

I think those peacemakers, you have to put the co2 in and then fire it to pierce the cylinder. Been awhile since I had one.

I cocked the action several times and pulled the trigger , no piercing of CO2 cylinder. I'm pretty sure that this is a common problem on many of these old style revolvers that have seen much use. Guess the only way to find out is pull one apart. Don't know if piercing pins are available if needed. If not, they are just revolvers to look at.
 
Put some pelgun oil on the cylinders which is actually 30 weight ND motor oil and use a screw driver if needed if they dont work I agree Eric at scopes and ammo is a good bet. Personally I enjoy them as paper weights versus fixing them. I prefer my single six. Aside from that they can be fixed if you are patient. Good luck. I have a 38t in excellent condition it takes a lot of pressure on the cylinder to seal after all co2 does run at 800 psi. they are fun! Do not use vasoline, I know from experience.

Yes, I've bought seal kits from Eric. I know some seal kits for various models have a new pin but I don't think they do for the 44, single 6 etc. I was thinking that if it is worn piercing pins, a seal kit alone won't solve the problem. I have had Crosman revolvers before that I acquired new and there was no issue piercing the cylinders with them. These revolvers that I speak of I picked up used here and there and none will pierce cylinders. I suspect gunrunner100 is correct and the seals have hardened to the point that the cylinders won't go ahead far enough. Guess the only way to know will be to tear into one and hope new seals will solve the piercing issue. Where's my tools!!
