GunSmith took liberties with my request for barrel re-thread

took my 2 FAL Projects into a Gun Smith to get the receiver or barrel threads matching, he went ahead and charged the thread on the barrels which where common Metric STG barrels the receivers are Israeli Cut
anyhow he took it upon himself to time the barrels TDC vertical @ hand tight (12 o'clock) and told me to add some green loctite and it would be O.K !
total disregard for 15 degree golden triangle and total disregard for my instruction to just re-thread the receiver

is there any way i can salvage these barrels ? perhaps add a Inch washer ?
if i had the barrel shoulder machined enough to hand tight into the golden triangle would i then have too much chamber protruding into the receiver ?

im in N.Z the barrels where true Metric STG and receivers where N.O.S FN made Israeli Contract with the funky 1" by 16tpi thread

the gunsmith should of known that the FN and Mauser barrels work on the same principal

You'll need a shim. Probably .005"

Use a piece of shim stock. Scribe it and cut scissors. You can punch a hole in the middle with a sharpened pipe nipple

He should have known better. Did he take metal off barrel shoulder or from receiver?

this is his last email cut n paste (special note: it was the receivers which where/are Issy cut threads)



Because your Receivers were different from barrels the barrels have had their threads recut to metric 1.5 pitch . Indexing is different so you cannot apply the std fitting procedure as per your Emails . They come up to 12 oíclock at firm hand tight so that is why 680 Locktite is used . If you had had metric barrels your fitting procedure works but not in the mix and match you had where the barrel threads had to be recut and re indexed. If you use the procedure in my first Email all will be Ok. Do remember the barrels are matched to each receiver and you cannot swap them as recut threads vary slightly. The Receivers have not been changed only the barrels.

If this guy is near enough to drive to, drive there and break his hands. I mean every finger, every joint or knuckle in his hands then use a 3 lbs sledge on the palms of his hands. Take every dime he has on his person and schwack him in the forehead before you leave. That is all

So did he alter the least expensive parts to get them mated up. I have read that's what you do.

Just noticed this thread, thatís a bummer Lee.
Even though itís not ideal, that shim will remedy your need.

hey Dean, the funny thing is the gunsmith has been in the trade for over 40 years yet still insist's his method is correct ! cant teach a old dog new tricks

do you think i should do my barrel timing with the same principal as a L1A1 using a shim in stead of a breaching washer i.e. get a shim thick enough that gets me in the golden triangle and then do final alignment

would i need to go outside the golden triangle to say 10 o'clock to compensate for using shim material ?

StG barrels are not metric. No FN, StG, IMBEL, whatever; or L1A1 has any metric thread.

The only metric thread on any FAL is Israeli barrel (chamber end only) and Israeli receiver (barrel thread only) M24x1.5, which is a 70% overlap with 1"x16.

Jury is still out on Indian rear sight screws & grip plate screw, and barrel thread (chamber end only). I doubt it, and attribute tightness to machining quality.
