Trying to clean "new" Cooey, barrel is stuck

I just bought a used Cooey Model 64 and I wanted to give it a good cleaning before taking it out to the range. During disassembly, when I tried to pull the barrel out, it shifted about an inch and then got stuck. I tried using penetrating lube to unstick it but it seems quite thoroughly stuck and I'm not sure what to do. I can't seem to even push the barrel back in now, so my rifle has been sitting in pieces for a couple days.

Any advice on getting the barrel free so I can finish cleaning it, so I can avoid this problem in the future?
 
Got a bench with a vise on it?

Wrap a towel or strip of leather around the barrel to grip it without marking it. hold the bolt back out of the way, wiggle and pull.
No vise? Figure out a ay to hold it all securely using what you have.

It may help to push it together first.

This begs the question "Why?".

For the most part, taking it apart was not required. If you break it... Oh well.

Anyhoo... Barrel likely has some small amount of a burr or difference in size that caused it to bind up.

How hard you cranking on it? If you can, strap or tape the bolt in the full back position and place a adjustable wrench (Cresent wrench style, not pipe wrench or visegrips) over the action with a layer of cloth or tape to protect the finish. Use that to wiggle the action gently, to work it loose.

Think lots! Then be careful. Otherwise you'll be selling Cooey Model 64 parts in the EE and cursing the day you decided you needed to take it apart to clean it(which like as not, you really didn't).

If I remember correctly you cant twist this barrel as the ejector slides along the barrel so be careful when trying to remove it...try using a rubber hammer and lightly tap the end of the barrel to push it back inside.. then keep working it back and forth or just clean it as well as you can and go shoot it...
 
Well, the rifle has been sitting around collecting dust for a while so I wanted to make sure it was all in good order before taking it out. There seems to be a little bit of gummy residue where the barrel is connected to the action. When I tried to pull the barrel out, it shifted about an inch and there was a bit of this gummy stuff. I tried using penetrating lube on the area and after some time I had my friend hold the action while I pulled on the barrel and we couldn't get it to shift. I'll take it to another friend's house tonight and see if using a vice will work better.

Edit: Whacking it with a rubber mallet pushed it back, so at least I know it isn't permanently stuck. Hrm..

Yeah it sounds like decades of closing the bolt has enlarged the breech end of the barrel a thou or two. I'd personally vice the action and heat it with a torch to expand the action enough to pound the barrel out. Don't let the torch touch the barrel though, you only want to expand the action circumference. Maybe a shot of penetrating oil around the barrel where it goes in and in the breech area. For pounding out the barrel try to use brass, I use a 1/2 brass rod I picked up somewhere years ago... And when you hit it, really hit it. You're better off with a few really good thumps than a hundred tiny taps.

Something which I know is controversial around purists but I like to do on old beaters with slip fit barrels, is use either bearing mount, or even better steel epoxy like marine tex or Jb marine on the chamber portion of the barrel where it slips into the actuon. Use a release agent such as paste wax on the inside of the receiver before slipping it in, and coat the retaining pin in paste wax as well. Makes for a perfect fit... But I'm a little OCD when it comes to tightening things up. And it won't glue it together, you just have to heat the receiver with a torch to break the bond. No problem with an old Cooey.
 
Tap the barrel back into place - you'll see it align again with the slot in the bottom of the receiver. Try different solvents - brake cleaner, carb cleaner, etc. and let it soak. Pull the barrel straight out as far as you can, and then just pull back on the bolt handle and let it go on its own, like a mini-slide hammer. It should tap it out in short order.

Yes, it's a slip-fit barrel, not press-fit. You could also try using a heat gun on the receiver, and an oil-soaked cloth on the barrel to keep it cool.

Click to expand...

This is important! Twisting the barrel will break your ejector!

I adore my 64's!
Some of these can be quite stiff. You can use the bolt itself to get the barrel to budge. Remove the retaining clip, pull the bolt back and let 'er fly...that usually gets the barrel going. If not, hold your rifle vertically by the barrel with the receiver on the bottom. Use something softer than the receiver to tap on the receiver. You can use about 300degrees of the receiver (you could use 360 of it, but you don't wanna tap the rear sight). Work over something soft so the receiver has something to land on.

Get used to the procedure. 64's should be thoroughly cleaned every 500-1000 rds, or they become jam-o-matics!

Once you've got it cleaned, run it dry. I only lube the internals for storage/rust prevention.

Enjoy a fun n' fine little semi!
 
Someone on CGN mentioned the upside down compressed air can trick for getting tight fits out. Basically freezes the metal so it shrinks just long enough to get things out. I've never tried it, but thought I'd mention
 
I had one do the same thing. I just used a small soft rubber mallet to tap all around the barrel in a direction away from the receiver. It slowly came out.
