I will look to see if I have one at work.
My father tried to swap out my barrel for me while I was gone. He didn't know he had to remove the front screws and gouged the a bit. I'm needing a tap 1 1/16 x20 to chase the threads on the receiver. I had found one online a week ago under $50 but can't seem to find it again. Don't want to put the $100 down for brownells and the gunsmiths around here told me "we don't work on savages" **** remmy smith! So if anyone can oblige I'd appreciate it. Or if someone used theirs and want's to recoup half their cost.
I will look to see if I have one at work.

You don't want to use a cutting die to restore the boogered threads. What you want is a thread restoring die or file such as in this set : http://www.sears.com/craftsman-48-pc...p-00942275000P
I Happen to have this set, and using the correct 20 TPI file you can restore the threads on the damaged barrel.
If you don't want to purchase the whole set, you can just get the file for external SAE threads: Less than $12.00 plus shipping: http://www.sears.com/kd-tools-sae-ex...45000P?prdNo=2
Don't need to fix the barrel, I've got a new 1" Bull going on it....problem is the old Barrel scarred up the threads. The kit you posted while it does have something to fix the old barrel, doesn't have the correct tap size
I have saved many a day since the mid 70's with those square thread files. A requirement for any handyman's toolbox.
If missed doesn't have one, buy the one at Rex then sell it to the next guy that needs it.
You don't need the tap, although it would be good, you use the thread restorer file to carefully restore the threads on the action(inside threads) and the old barrel (outside threads) so they are both good again.
If you don't want to spend the time with the file, buy a tap, but for the best repair job, make sure it is a thread restoring tap, which is designed to reshape the metal back into the correct form, as opposed to a regular or cutting tap, which will cut off anything except the thread, thus leaving the thread not fully formed (usually not as deep) in the areas where it was scarred up.
buy the tap from rex get a plug tap run it in by hand no tap wrench you will be good to go
I may be mistaken but for the sake of discussion, the tap will actually cut deeper than the OEM barrel threads need due to the thread profile. The UN threads that are cut on the barrel are UN2 I believe, with a larger radius at the root(and peaks) of the threads, that radius resists stress fracture propagation. Probably not a concern in this application with regards to the internal action threads. The question is does it change the class of thread by making it a class one rather than a class three. Much like the example thomae used for the external thread chase. Something to consider when using a tap of unknown dimensions.
I must ask why no tap wrench. If used properly...vertical it allows you to keep rotation torque on centerline more easily.

You are mistaken.....the thread size is 1.062" x 20 tpi, with the same pitch diameter. Only the barrels are undersize on the crest.
"As long as there's lead in the air....there's still hope.."
The receiver threads are thread milled, and have a tolerance that sometimes the is not adhered to. Depending on the machine, sometimes the threads are not 100% round. I usually always run a tap in to uniform the threads.

Good stuff. thanks. BTW how's business?
A tap is a poor way to do the job use a lathe.
I couldn't find that tap at work. We had thread pitches that were close but not that one.
I had a feeling. LOL We have a lot of taps as well but not that one. No problem, I think Captlink is offering to do the work for you.
IF not...did I mention this.

For cleaning threads at home it is not only not a poor way but the only way.

It was a suggestion for the best way.Many times a receiver is threaded with a tap at the factory and is not true.No matter how you do it the barrel should be checked for head-space after barrel installation.Find a general machine shop if you go with a tap it's a minor job and if the guy is nice he may do it for beer money.
No argument there.
Please explane the hobbing operation of a receiver before threads are cut.

wont help op this time but there is a thread on here somewhere
that says to tighten front scope mount screw 1st to see if it bottoms out on barrel threads
leaving scope mount loose
if it does -shorten screw till it don't
better accuracy & the ability to change barrels without removing mounts -
one member even posted a pic of a barrel swap jig he made
that allows leaving optic in place
a wooden jig & a modified nut wrench used with a rear entry action tool
