Well an update to this project.
First the barrel didn't get cut and I learned a little more about the LE system. it seems that sometimes the armorers just screwed the barrel in a little deeper to tighten the headspace. Apparently PH was not exempt form doing this also. Mine was at .066 so Jess saw no reason why he couldn't not screw it in so far and get the front sight to line up properly. So I still have a 22" bbl. which is fine. It has a #1 bolt head. Also I should have it back by next Monday or Tues. I have to build an oven soon to cure the Cerakote. That shouldn't be a big project but I still have to get out and do it. Randy

So, Jess removes the barrel to rebore and then when he re-installs it he just doesn't torque it down as much? |

My barrel in it's correct position would probably still have the .066 headspace that it had before, maybe .067 at most. that is still on the tight side for these guns. as .064-.074 is acceptable. 3-5 degrees isn't going to make that much difference.
If anyone knows the thread pitch for those barrels we can figure out exactly how many degrees .001 would make. Randy

Randy, I believe the thread pitch on those barrels is 14-1 TPI.

1.000/14=.071 per revolution. .071/360= .0002 per degree. 5 degrees would equal .001 in the headspace.
makes sense. Randy

OK expecting this thing back early next week. Need to find out some things as far as powder numbers for AUS and how they relate to American numbers.
Particularly 2206 which I believe is H4895 ,,, and 2208 which is I don't know what? I saw some loading info on Jacko's thread about .303-35 using cast boolits but he only referenced these two powders. Maybe some of our friends from the lower hemisphere can enlighten me. Randy

OK my barreled action returned from Jess yesterday with the front sight timed right and rifling that looked like it had been lapped.
Absolutely beautiful work! As I mentioned before I got 4 groove rifling. Jess was also kind enough to give me a .35-303 case to play with. Got to find a Boolit Mould. Proceeding to finish work now. Randy |

Here's some pics of the detailed internal parts. All are ready for bluing which will be done with Birchwood Casey's Super Blue. They will all be treated with Frog Lube immediately there after. The only parts visible from the outside are the safety and the bottom half of the trigger.
The exterior of the barrel had been welded on to fill some small rust pits. There were some evidence of poor filing technique which had to be dealt with. I literally used a Finish Sander with 120 grit WoD paper on it and sanded most of the goobers out using fast lengthwise strokes, and rotating by hand as I went. This took about 20 minutes checking frequently for progress. Before anyone goes,,, Oh my God you've ruined that barrel and it has been "Welded On!" I took maybe .001-.003 off parts of the exterior. The welding was only done on the surface and it wasn't that deep to begin with and poses absolutely no danger whatsoever. Also it should be noted that the whole thing will get grit blasted before it is coated with Cerakote which will hide the vast majority of the things I didn't get out. Most are below the stock line anyway as they were rust pits caused by the metal contacting the wood over the years. I still have to deal with the bolt itself and I think I am going to Cerakote the main part and the cocking piece. There is more than enough clearance for it to run smoothly in the bolt race after both are coated. The guide ways on my CZ82 were all coated and after 100+ shots they still have no evidence of wear! I think it will work out well. Randy |

It sounds like "breaking the edges" or "dehorning". Something we used to do to reduce snagging & binding.

Some nice preparation going into that rifle Randy. It's great that you can get the time necessary to do the job properly.Looking forward to seeing the finished article.

Hoadie: this product is a commercial cold blue solution that works really well for touching up places that got the bluing worn off.
It can even be used to completely reblue a gun however it is not really that good for that purpose as it doesn't have the same penetration as hot bluing does. It wears off much easier. But still if you don't want to put that much money into an old gun it will do a presentable job and is a lot better looking than bare spots. I will use it to touch up parts or darken weak bluing on a barrel or to finish parts I make for the gun. See the Redfield Sight Mount I made for the #4Mk1. I did all the parts on my #4 mk1 which were mostly in pretty good but partially faded condition. I darkened the bluing on the barrel as well on that gun and it also evened out the finish. The parts for this gun as you can see in the above pics will need some touch up as I have removed the bluing on the edges when I deburred them. The stuff is available at most gun shops and is about $10 for a bottle which will go a long ways. Shamu: "deburring" covers part of it. Refining lines and removing tool marks is the rest of it. As you know there is plenty to do on an Enfield action. Zed: I will have probably 20-30 hours over the course of 3-4 months into this gun before it is done. That is a relatively short period of time overall, and your ability to work thru a project in a systematic manner can keep it to a minimum, but it still takes time as in the end you still have to do things right. Sometimes I have to do things over. I go back and forth working on the wood for a while and then metal, and by doing this you get a really close look at all the parts,,, numerous times. Doing this allows you to develop a good picture in your mind of how you want the end result to turn out. This picture will evolve as you work thru the project and in the end you should be able to get closer to what you "actually want," as opposed to what you "thought you wanted." Randy |
