Thanks Peter,
Prior to your post I decided to try and mill the backside of the locking shoulder to preserve any hardening of contact surfaces.
Success! I now lock up on a .064 gauge and do not on a .067 gauge. I now have to slightly elongate the srew hole in the receiver and stake everything in place.
Thanks tremendously for your thoughts.
Yep......., on second thoughts I think that your idea is the right one because a) elongating the locking shoulder screw hole is slightly academic as it is a re-weld in any case and b, it leaves the remainder of the geometry as it should be. But I would advise that the screw is just a means of holding the shoulder in place and does absorb the recoil. The actual RECOIL energy or force is directed through the locking shoulder rearwards and back into the body of the gun. For this reason I would try to make sure that the rear surface of the re-ground locking shoulder matches/mates up with the surface area of the body supporting the rear of it as best you can get it
Please ignore all thoughts of a .067" gauge. This size does not feature in any Bren EMER. The No-Go is .074"
Right............ First detail on the firing point. Down test and adjust. With a magazine of 30 round, ........LOAD............! READY..........! Ooooops, Sorry..., just got a bit carried away and dreamed that I was about to run the Bren ranges again!
Peter, as you said I got a real good fit to the body with the locking shoulder and still have some slop in the screw hole.
Just put a full magazine (well 28 rounds) thru it and it ran really sweet.
Now to clean it up and Dura-coat it.
Again thanks to all.
Thought I would post a picture of a few of my Brens :)
Havent dropped in for a while & only just seen this!
Peter pretty well had it covered! The only 'usual' gauge sizes for 'Normal' use (Usually at Unit level) would be the same for the Enfield Rifle. .064" -.074", that gives you eight thou to SAFELY play within!
As Peter points out. There are many variables in your area of construction. As it's a reweld, there will be MUCHO metal missing inistially!...getting it all back together again, within the correct tollarance sizes. Will be a tricky & time consuming project! so much to deal with here at a cut-up level, you have done well to get it all back & the internals running in line & correctly in the first instance!
I know that Peter & myself, had absolutely NO trouble back in the day. CUTTING Brens up to destroy them!...........Makes me weep to think about it now. But, back then, there were thousands of 'em floating about in the system. & you couldnt store THAT many in War reserve!....
It's hard enough these days Deactivating good running examples. Without the thoughts of them being Gas-Axed up for parts kits!.....:(
Just to REALLY pile on the misery. The Aussie Govenment, is cutting up all it's 7.62mm Converted L4's!.....Now that REALLY upsets ME!.....:mad:
