Well, another update on this project:
I cleaned the barrel and comp and started looking at how to fit it and seat the threads better this time while keeping it timed.
I was going to just get a valve lapper and trim it down and hone the treads, but then you run into the issue of rolling the leading edge of the thread Unless you have a plug to put in the comp threads beforehand which could be removed and roll them back out after done.
Then I thought about a good crush washer, or how I might machine/fab one.
Then I though about taking a large ead bullet and drill/mill/file to hearts content.
Then I though about fine solder wire. It's Free(I have it for microship soldering apps), easily malliable, should be heat resistant... hmmm.
So I rolled a bead of small solder on the shoulder of the barrel under the threads and put the comp on expecing it to be swaged. Got it tight and took it off and nothing, the solder wasn't even touched. closer inspection shows that there was some contact on the face of the comp to the barrel bushing. Filed that down vary carefully at first, then realized that if the comp bangs aginst the barrel bushing it would not be ideal and would be one more thing to shock and break the comp loose out of time. So I then filed the piss out of it, not giving a crap about how it looked, just clearanced it. you could tell it was contacting the top of the barrel bushing by holding it up to the light and looking for gap, use of automotive feeler gauge was a no go, and dyechem. Once it was a few thous clearance, I remove the barrel from the slide and moved on to seating and timing on the actual barrel to comp threads.
I tried a single thread of the fine solder, still not enough. Then a twisted pair and started to see some flattening.
Finally ended up with three loops of the fine solder. Put the comp on and timed it, seems good, spun it off and the solder was a bit jacked up because the way I wrapped it the comp caught the outside end of the solder wire and looped it out of seating some. I reversed the direction of the loop of solder so when you spin the comp on, it doesn't catch the end of the solder wire. Then tested one last time with all installed in the slide/gun, seemed good. the lockup isn't quite as tight as I'd like ti to be, but it is much better.
One more good cleaning and some red permatex that I still have on hand and its drying now. I'm going to give it another day and then try dry cycling it (before comp would come OOT with just dry cycling). If it passes that, will try some minor rounds through it this weekend.
If it fails, my next try might be some good high heat locktite, more solder swaging. If that fails - I do have mapp gas and some silver solder. I'm going to take my handheld temp laser gun and check the temps that the gun/comp gets to and also what point the solder I'm using melts.
As the "Ream a Chamber for 9Maj" is pretty much done, I'm about to retire this thread and start another one in the gunsmitihng side as seems more appropriate.
