I receceived a '28 parts kit recently and would like to remove the barrel from the cut receiver nose section that it's still screwed into. Questions: I don't have the 'correct' barrel removal tool but I've heard others have done this using a wooden board with a hole and the barrel between 2- 2"x4"s. So if i'm holding the barrel straight up with the cutts comp. at the top, does the barrel need to be turned clockwise... or c/clockwise? And where do you apply the torque with the board with the hole, on the compensator?... any chance of Cutts holding pin breaking if done this way? Would soaking the receiver section in some kind of penetrating solvent help aid barrel removal? Any help in correct way to remove would be greatly appreciated.

Do yourself a favor and have someone equipped to do the job handle it, the parts are worth to much for a hack job.

If the barrel comes right off it should be pretty cheap. If it’s a bugger, it still won’t be very expensive and is really in need of an experienced hand.

Well, I appreciate the advice however I'm not totally without shop skills myself it's just I've never tackled this animal before. I would certainly know when to stop before ruining any parts. I would simply like to know the correct proceedure if anyone could provide me with it.

The work “hack” is a bit strong and no offense was intended.

Without the right tools I don’t feel I can offer any advise that would help other than I have.

Mike, here is some info, and I hope that it helps. The following was barrowed from an article written by Doug Richardson. (Copyright 1996)

1) Clamp the barrel between two blocks of soft wood in a large bench vise with the barrel pointing toward the left. Grip the barrel close to the receiver with the grip mount up and torward the rear vise jaw. Apply a large open end wrench to the receiver nose and try unscrewing the receiver nose counter clockwise off the barrel. If the receiver turns, the grip mount will rotate with it and strike the front jaw of the vise almost immediately. It is very important not to twist the grip mount by forcing it against either vise jaw. At this point, if the receiver has turned off the barrel even slightly, go on to 2. If the barrel turned in the vise, release the barrel, rotate the grip mount back to the rear vise jaw, and try again with the vise tighter. If the receiver will not break loose from the barrel, go to 3.

2) Remove the barrel from the vise and discard the wood blocks. Clamp the receiver nose section in the vise with the grip mount at the back side and the barrel pointing toward the right. If the grip mount is the later type which has the retaining post rivited to the bar, grip the nose section in the vise up to the rivited overbump so as not to crush it. If it is the one piece type, clamp the nose section in the vise up to the barrel. Pry the front end of the grip mount away from the barrel slightly. Insert a piece of cardboard (e.g. business card) between the barrel and the front projection of the grip mount to prevent the grip mount from gouging the barrel as the barrel is turned. If the barrel is finned, the grip mount projection will drop into a fin groove as the barrel is unscrewed. A horizontal forearm mounting bolt screwed into the grip mount hole can be lifted by a claw hammer or a crow bar to hold the grip mount away from the barrel as though the bolt were a nail being pried out of a board. Be careful not to pry the grip mount further away from the barrel than is absolutely necessary because it can be permanently bent. Grip the barrel next to the receiver with a strap wrench and unscrew the barrel.

3) Soak the barrel/receiver assembly in gasoline overnight. Dry completely with an air hose if available. Go back to 1. and try again if the barrel won't unscrew. Heat the receiver nose red hot with an acetylene torch without directing hitting the barrel or the grip mount with the flame. Do not allow the barrel or the grip mount to turn red. Let the assembly cool and then go back to 1. Repeat if necessary.

The above again was taken from a Thompson Technical Article written by Doug Richardson. He has a Catalog available for $5.00, featuring tools, Display Receivers, and his own books featuring A LOT of useful information!

Again, I hope this proves useful!

Lionhart beat me to the punch.

I too was going to recommend soaking the barrel, but couldn't remember the liquid to use and if it was gas or oil or i think someone even recommended brake fluid or something like that.

Since your probably not concerned about the receiver, clamping should work fine. I used the wood with the oval hole before and it worked great, but my barrel was not the original and probably a lot easier to remove then yours will be.

Good Luck!!

Mike;

I'm with PK on this one. He's been at this a long time. I'm sure he didn't mean any offense. And neither do I.

I think....that what we might both be saying that without a good barrel wrench, it's very, very difficult - if not practically impossible - to remove the barrel without at the least....marring the finish....and most of the time (again, this is without a proper barrel wrench) gouge the steel. I've got some experience in this thing and can only say that having a few removals under one's belt reveals the 'tips and tricks' that only experience can provide. Besides this, everyone here is only trying to help you preserve a rather hard to come by kit.

The link below shows removal and installation of M1A1 bbls. It also shows several bbl wrenches. I think you'll find this is one of those 'picture is worth a thousand words' times.

And don't forget to mention that the $75.00 for the unique barrel wrench that Doug Richardson sells is worth every penny!

I wouldn't tackle this without a wrench as the barrel is probably worth more than the price of the wrench anyway, and you'll need a wrench when you put the barrel back on whatever you intend to use it on in the future.....


good luck!

I don't think the Doug R. barrel wrench has been available for quite some time...I think Doug is trying to get caught up after his recent eye surgery but it could be a long wait. Why not have an expert do this task and avoid any possible damage to those parts! I tried it years ago and ended up messing up a nice M1a1 barrel and cutting the grip mount off with a dremel...talk about a hack job!!!!!
Both PK and Sam Alvarez (T&S) can be trusted...they have been on these board for quite some time.

[Mike Hammer]

Many thanks for all the fine advice, especially you Lionhart for taking the time to list the proceedure as outlined by Doug R. I'm sure this thread will help many who have a barrel removal job to do, they can now make an informed decision on how to the job themselves or paying someone else to do it.

Some bbls come out easy...some come out harder...rcvr nose on left cut right to bbl threads then peeled back before bbl would come out...rcvr nose on right was the easy one:




inexpensive bbl wrench:




expensive bbl wrench and bbl jig:

Phil: You said it all pal, I truly fear what is happening to this country. Just in my short 48 years on the planet I've seen the progressive moral and intellectual downfall of the American society. The socialistic attitudes, (read communisim) that has pervaded the mindset of not only the politicians but of the general public, has destroyed and is continuing to destroy all the freedoms we started this country for in the first place. The new American seems to want the government to take care of there every need and with that we are becoming nothing more than cattle, a creature kept to fullfill the hunger of the bloated and ever growing elitist government machine. Some may think my attitude severe but I would say to them 'Open your eyes'.

Hey Guys,
When in gods name did they pass this "no parts" law?!!!
I mean, I have really about had it up to here with the amount of frikken taxes I pay, they sneak this crap through??? How can we keep track of what they are proposing?
I'm up to date with what McCarthy want's to do with our semi Westys and Kahrs ( put them under assault rifles and outlaw them), but this importation of parts just got by me.
Really, VOTE VOTE VOTE these bastards out, man, this burns me up.
in complete disgust,
Zamm

[Grey Crow]

In PA SMG's are still legal. For how long it's anyone's guess.?!?!? Now they want to list the 27 and M1A1 on the assault list! 4 months wait for your stamp to buy a semi. Those who own high end machine shops can always turn out what ever they need, parts or entire arms. The day is coming by the look of it all. Those who own NFA weapons will surely be the 1st doors that are approached, at the redemption price for scrap metal.

As to booze, here they just lowered the level of alcohol that determines if one is DUI. Then if you get drunk and try not to drive its public drunkenness.
Sounds like prohibition all over again. Only this time without the Thompson's or B.A.R.. Oh, don't forget book burning, Fahrenheit 451 anyone????

Yes, it's all in the name of protecting the countries citizens, when even the law states that they can't protect us.

I have a carry permit for concealed/loaded firearms, but can't carry in Philly. (City of Brotherly Love) LOL< yeah right, Philly is where you need a gun the most.

Similar to Capitol Hill in D.C., robberies in broad daylight. One thing for certain the thief is safe because the law abiding citizen can't protect himself.

I think that the referance to prohibition is interesting...has any one noticed that prohibition ended about the same time as they passed the 34' law? create new crimes overnight by passing prohibition in 19' Wait till it has almost run it's violent course, rampant crime with "blazing Thompsons" of course! (villify the gun if you will) then cry for the need for registration, taxation and virtual control of machine guns while repealing prohibition which started (for the most part) all of the violent uses of the Thompson!

[Bob]

I think "Taxed assets" would be about the last to go. The .gov can shut off transfers any time they want and when they shut down NICS system (look how many times has the system been down so far), it can stop the legal transfer of title 1 guns. Hmmm what to do, what to do?

[Bob]

Oh no, too old to change country of citizenship now. Anyway I paid my dues to the United States and don't want to leave!

I think changing my corporate address to "go 37 mi past the stump on the intersection of Hwy 51 and old wagon trail road, north of Elko, Nevada" would be a better idea. (This is really not my address so don't look for me there...yet )

[Walter63a]

PhilOhio, I totally agree with you! However, don't forget, Josef Goebels (Hitler's propaganda minister) once said, "We (the Nazi Party) will not rest until we get the power." When the Nazis finally came to power in Germany, there was 'gun control.' The Nazis controlled the guns and the people! Sounds familiar, doesn't it!? Regards, Walter

Walter, Where are your papers?
