Another BREN-fan (introduction)

[erik3D]

Nice animations @SNAFU22, but what I am thinking of would be much more in detail than these.
The way the extractor is tightened by the boltcarrier during unlocking for instance, that's quite unique for the Bren as far as I know.
And something I certainly didn't notice while handling, shooting, and (dis)assembling one.
A LOT of work though, animations like that!

What I would very much like to see clear pictures of is the 'Ejection Opening Cover Catch'.
Don't know if it's easy to remove, hope it is.
The one I've modeled now would probably work, but it isn't based on solid, detailed information.
Thanks in advance for (hopefully) taking the trouble SNAFU22 !

Seems like there is always one more pic I should take. A stop screw in the lower keeps the the latch pin from lining up with a hole in the lower. Remove the screw, align the holes, and push the pin out. Can you "stamp" the E in the D on your latch?

@SNAFU22 Thank you very much for those photo's !
They are of a newer version of the catch than the more curved Mk1 model, but functionally they should be very similar.
There is a small vertical projection, or pin, in the sliding cover itself that I haven't seen before.
Haven't got a clue what that is for, but I assume it is some kind of improvement.

'Stamping' text or symbols on/in 3D-models is no problem at all.
Hey, I could do some nice scroll engraving with gold inlays and a hunting scene on the sides of a Bren, there's plenty room for it : )
Here's an example of a roll engraving on an old Smith&Wesson revolver I've modeled recently:

For this I just need a good image, from a photograph for instance, so I can convert it to 3D geometry.

Here's a 2D drawing of a fully compressed Bren recoil buffer.
The receiver (or body) is also in its rearmost position.
(the section plane is in the centre of the buffer, not in the centre of the boltcarrier, they are offset to each other)
It appears the bolt (or breech block) is stopped by the lower receiver itself, not by the buffer.

I've found some old photo's of a visit to Nottingham, many years ago.
Brings back memories.
Here's one of them:



(I photographed the print with a digital camera, so the quality isn't too great)

Cheers!

I'm afraid I have to confess that back then to me this one was much more interesting:





Sorry 'bout that

There were several variations of the catch, cover, ejection opening. The last version was one of the last modifications for the L4 gun. I seem to recall that it had a longer 'catch' part so it would engage and hold open a few mm's sooner.
