Best Penetrating Oil?

[Irish]

Hey guys,

Can anyone recommend a really really heavy duty penetrating oil?

I have a barrel that was threaded into a receiver in the early 50's, think it was put in by King Kong as I'm having a devil of a time trying to remove it.
I reckon I need to soak the bejesus out of it in some penetrating oil to try and make things easier on myself as I don't want to damage the receiver.

WD-40, RP7, CRC and the like have failed miserably.

Any ideas?

[Sir Roofy]

heat it up till glowing that will do it

[Irish]

Thanks Roofy,

Will that run the risk of frailing the receiver though? Don't want to run the risk of copping a bolt in the face, I've heard that can be a bit uncomfortable.

Prep H or KY will do the job, shite sorry wrong thread lol

Heat or shock will normally shift most things

[Irish]

Hahaha, I don't have any KY mate, I don't drive a GU.

Present company excepted:-)

How deep are your pockets? There are some good ones out there but you will pay for them. If your worried about to much heat use a combo of heat and penetrant.
Also try doing it up sometimes you can get it moving just a touch then undo it.

I swear by trying to tighten a touch first before undoing.... rost off was what we used in the bike trade..??

[threedogs]

Even try a can of "Freeze it" from Bunnings
Too much heat changes the temper too much

Its just the FN mauser(60yrs old) being a stubborn git of a thing, original military barrel has probably had a squillion rounds through it over the years and flings lead wild at anything over about 25m.

I found a diy recipe for a penetrating oil thats supposed to work better than most of the brand name offerings, uses a 50/50 mix of ATF and acetone, might give that a go as I've got both of those in the shed.

I must have some kind of thing with barrels, my Enfields barrel was loose when I got it:confused:

[Irish]

Okay, I can officially vouch for the abilities of a 50/50 acetone /auto trans fluid mix as a penetrating oil.

Throw out your wd40, crc, rp7 and just fill a spray bottle with some of this.

had win did we

Big win mate, one love tap on the action wrench and she came good. Very satisfying. Made the action wrench from scratch from some flat bar and some rhs box section, cut the barrel blocks, with that home brew oil it was easy as. just shows what you can do with some basic tools.

Use some hardwood(oak in this case) to make some barrel vise blocks

Set the whole shooting match(no pun intended) in a BFO bench vise(thanks BA), applying rosin to the blocks and a dab of gorilla strength to the vise

Liberally apply one of these to the end of the wrench
