The restoration, (BDL FTR), of a Bren Mk.1

[Brian Dick]

The restoration, (BDL FTR), of a Bren Mk.1 receiver/body manufactured at RSAF Enfield in September 1940.

I took in this repair from a friend and client last Fall and finally completed the project last month. Special thanks to Peter Laidler and the other REME Armourers both current and retired for their tireless guidance and patience helping me through this project from long distance. There were some VERY tense moments, especially while removing the worn gas cylinder. The result is nothing short of PERFECT.

The work completed includes changing a worn Mk.1 gas cylinder to the much improved Mk.3 type, refinishing the receiver/body with Parkerizing, spraying and baking on Suncorite 259 paint and last but not least, (the fun part), reassembling and test firing the gun.

The first photo is the receiver/body freshly degreased, glass bead blasted and with manganese phosphate applied. Note that it's a rewelded receiver brought back from the scrap yard prior to the U.S. ban on new manufacture transferable guns in May 1986. Also note the newly installed, excellent condition, Mk.3 gas cylinder which cures it's low gas problem with some left to spare.

Very nice indeed.Any tips on applying the Suncorite (apart from not inhaling !)

Suncorite, to be applied properly, must be baked on at a specific temperature and time. I think Brian can do that sort of thing.

[Brian Dick]

Thanks for the compliments.

The Suncorite is slightly thinned and sprayed using a medium size spray gun. An airbrush is too fine for a sizable part like a Bren body. I wear a respirator while painting. Bake it for an hour at the correct temperature, (200C or 400F), and you're good to go.

So when's the tutorial on swapping the gas cylinder coming out? My poor semi BREN had to have all the exhaust ports covered in finest Bubba fashion to function properly.

[Peter Laidler]

That's a superfine job there Brian. We'd call that an 'apprentice job'. That's when an apprentice knows that he's being critically marked for a stage in his training and he makes sure that it's perfect. It looks to me like that gun was what I'm calling in the forthcoming book, a Bren Mk1 1st stage intermediate. That's the first stage of its morphfication from an original, early, all singing and all dancing Bren into the subsequent, cheapened Mk1A Bren gun commencing in the 'F' prefix serial number range. Anyway, well done Brian

J-M and others, there's only one reason for a Bren Gun not to function properly and that is broken down into two parts.
1)Not enough gas or
2)Too much friction.

We used to call it too little and too much!

Is there anyone who wants me to elaborate on any of this over the course of the next six months or so?

A good dose of this should cure both problems !

You been hanging around with Ed?

Please do!

In my case, its not enough gas to work too many springs! (Dad-gummed cobbled-up ATF approved rewelded striker-fired semi-auto, w/ a horribly eroded gas cylinder!)
Just couldn't justify spending $30-40,000 on the real deal even when I had that much liquid cash! Ain't happening again for a while, I suspect.
