Reflex moderator problem

[matt_hooks 188]

How did we get the mod unstuck on your springer Matt, was it just brute force in the end or heating? I know just about all the lubricants in the house were tested against it and failed.

 

I think it was a combination of a great deal of brute force along with a good deal of ignorance, on my part anyway! That wasn't corroded on though, it was just an extremely good interferance fit, plus I think we had to drill out the grub screw. But that was on a £100 springer with a £5 mod, not a £500 rifle with £250 worth of mod on it.

 

Warming the barrel gently might well help. The expansion may serve to break the corrosion that's bonding it to the thread. Not sure how you'd warm the barrel without warming the mod though, and I'd agree that firing it might not be the best idea if the bore is in an unknown condition. Do you know anyone with a boroscope?

Yeah. It says "you are in for a big surprise. Things will really go with a bang next time you are out."

 

Whoops. Misread the last word.

Sorry Matt, I dont want to contradict you, but if its welded on and you heat the barrel it will make it even harder to unscrew as you will be heating the male thread and what you want to do is heat the femal thread.

 

What you could try is going to you local plumbing merchant and getting a can of pipe freeze:

Squirt some down the barrel to chill and shrink the male thread, you might just shift it?

Thanks Jonno, I fully understand the use of differential expansion to free a joint. What I was suggesting was to use heat on the barrel to break the bond, and then allow the barrel to cool. Hopefully the expansion and contraction will break the corrosion products enough to give you some movement.

Sounds like you have tried all manner of things but....

 

1st I'd leave the barrel/mod soak in Paraffin for a few days, then I'd get one of them car engine oil filter wrenches, the ones with a rubber belt that self tightens on it's self. Attach and give it a turn, I bet you it will come off first time.

 

2nd if that didn't work, off to the gun shop I'd go.

 

Bet you the barrel & crown are well knackered.

Hi i was just talking to my local gunsmith about the very same problem he had with a customers rifle mod his solution im afraid was to cut the mod off with a small hand ginder so he could get to the thread on the mod and cut the thread part through,after all that he ended up cutting the old thread off cut a new thread and crown plus new mod.Moral of this story should have tried mod off before buying rifle also when job done never leave mod on barrel when putting back in gun cabinet.Hope it sorts its self out for you.

 

 

 

Cheers Beardy.

Does anybody know if Jackson rifles would stand by the guarentee and 40% discount if the mod gets cut off and is sent back to them in two halves?

Finally got the rifle sorted. In the end the gunsmith had to resort to a pair of stilsons and a lot more brute force than i dared to put on the moderator. By the time it came off the mod was crushed. Jackson rifles honoured the guarentee and sent one down with %40 off of the price. Barrel had to have 3 inches cut off as crown and muzzle knackered.

That's impressive, we all know that Jackson Rifles STILL made money on the deal, but thats a better deal than I know of from anyone else, so hats off to Jackson Rifles!
