Cooey Model 600 bolt question

Thanks for the advice. I got it apart and cleaned up. The firing pin is pretty flat and needs to be filed to a point or replaced. What can be done and how does the pin come out?
 
I think it is giving light strikes. I tried 4 Velocitors last night and the first 3 went off on the first strike but I had to put the 4th back in and try again before it worked. Is the spring weak? Solutions?
 
The bolts are very hard to deal with. I would suggest taking or sending it to a smith to get it serviced. There is a lot of tension on the springs inside and you can get hurt if you do it wrong. I beleive special tools are required also. I never have tried and let my smith do it right. he can judge if parts need replacement at the same time.
 
Cleaning Cooey bolt

dont let this thread go! i was friggin around with an old cooey bolt this morning, how do they disassemble? mine is gunked right up

Go to an auto parts store and get a spray can of Carburetor Cleaner. Make sure it has the little extension tube. Then take the bolt out of the rifle, take the bolt outside where it is ventilated, wear safety glasses, attach the tube to the nozzle and spray the bolt. You may have to do this several times before it comes out clean. Then LIGHTLY oil the bolt with a good gun oil (NOT 3 in 1 - it does not displace water and will rust underneath.)

Two CAUTIONS:

1. Make sure you spray the bolt outside, holding it downwind, and wear safety glasses or goggles. The fumes can be hazardous to your health.

2. Do not spray it inside the house. When your wife smells it, it WILL be hazardous to your ### life.

Do you spray into the firing pin hole? Or just around the the whole bolt?

And would using compressed air be good following the carb cleaner and before oiling?

I have used compressed air but you really have to be careful with it. It is usually under more pressure than the solvent. Secondly, it can be dangerous. It can blow solvent/dirt into the pores of your skin, and if you have a cut or sore, compressed air can put air into your blood system. This can stop your heart!

Usually, a few sprays with the Carb Cleaner will loosen and flush out any dirt, crud, etc. Spraying into the firing pin hole is good. You might even put a small piece of wood between the two parts of the bolt to keep it open so you can spray inside.

Disassembly of the Cooey bolts is not recommended. They are really difficult to disassemble and re-assemble. Flushing with a good solvent into the nooks and crannies, then lightly oiling the bolt is best.

Thanks for the info Buffdog (my cooey likes to misfire sometimes, I think it's the firing pin full of crud).

Not so sure about compressed air in the blood system thing thou. Unless you have a open vein or arterial bleed. The air would go into the capillaries and get exchanged into the blood stream. Or get subcutaneous emphysema (mind you I've never seen it in the arms or legs before--chest and neck yes, other places, no)

It actually takes quite a bit of air to get the heart to stop. I've seen patients get almost a full solu set of air before the IV starts dripping. I don't know all the in's and out's of air in the blood stream, as I'm not a doc or IV tech. But I do administer IV's as a medic
 
Blowing parts with compressed air

Personally, I really don't want to experiment to see if compressed air will get into the blood stream. Maybe we can get the mother-in-law to volunteer for a test case, but that would be wishful thinking.

The Workplace Health and Safety acts and regulations say " DONT " so I think I will pay attention to that.

It's also a matter of nozzles. Some of the older ones have very small openings, and will really build up air pressure. Newer ones have a couple of holes in the sides, and if you put one on your skin, the air is deflected sideways through these safety holes.

As an aside, I was in a Perkins restaurant in Winnipeg this morning. I went to the washroom, washed my hands, and they had an air dryer there. Man, I'll tell you, the company that made this one must have manufactured afterburners for jet engines or something. If you had enough cord and sat on it, you probably could have flown it.

Anyways, I mentioned it as a caution.
