Very nicely done.

You are the first that I know of to finish one of the receiver castings and build it into a working FAL.

Great work.

Were the castings heat treated or did you do it or have it done by someone else?

Both rifles look great!

I like what you did with the front sights on your cast build

Thanks,

The idea was to come up with something a little different for the local IDPA side matches I shoot in.

I shaved the front sight off and cut the top off the rear sight base so it matches the top line of the stock.
I've been running an ATN ultra sight on the tapco cover, but lately it won't stay lit so I put the scope on till it's fixed.

The finish is Dupli-Color 1200 spray paint cured in the oven. In addition to shaving the sights I made a side sling mount, modified the selector lever, made a new knob for the Izzy charging handle, and modified the production sling mounts so they accomodate Uncle Mikes quick release swivels. The HG and stock are sanded, glass beaded, and then polished with Rolite to get the smooth matte finish.

Nice work. How many dremel wheels did you go through finishing that receiver?? Can you post some instructions for the rest of us??

You must be far more skilled than your average WECSOG gunsmith around here. I think there is an outfit in Oregon that is looking for a good machinist to finish some half-done FAL recievers.

I like the brake on the top rifle....must be a custom job by you too??

Mad Dog 7.62,

After what I've read I think I'd pass on that Oregon trip

I did that brake about a year ago. I'm not sure how well it works though. I shot both guns this afternoon. They feel different and sound different, but I don't notice a difference in felt recoil.

I actually made a few brakes/muzzle-weights for the new rifle but didn't use them as I got impatient to finish.

I don't suppose we could get close-ups of the upper-receivers?

Nice FALs sir!

NICE JOB!

Couple of requests/questions:

1. Close ups of the upper receiver;

2. Where did you buy the 60% casting - tannery shop? Tapco?

3. How did you heat treat it? You have a kiln for that sort of stuff?

THANKS!

BTW - Nice addition with the SAW grip. I'm partial to them myself....

Thanks all,

A guy at work said he's going to bring in his camera tomorrow. If he does I'll see if I can get some closer shots of the receiver. The big problem is that my camera just won't take a close-up shot, so I have to find a better one. Bear with me

I got this casting from tannery shop. I also have two from Tapco. They are identical. The only difference was that I paid 65 bucks for it Got the last one from Tapco for 17!

I hardened with a torch. Only a few places are hardened and it wasn't too difficult to do. Distortion was minimal and did not affect function or fit.

recce, I really don't know how much time the machining took. I think I've got about 80 hours total time invested, but a great deal of that was spent measuring and figuring out setups. I have no doubt that the next one will go faster.

JJH, the sling is a snap-sling from Uncle Mike's, it's attached to a 1/8" plate that is between the lower and the stock. (the front of the stock is relieved by 1/8" to accomodate)

and the right side rear (here you can see the spacer installed between the ejector block and the pivot boss)

stargazer, right now the only way I know to get the grip is to just dig around and ask everyone you know to look for one. (waving money helps )

762minigun,

Thanks man

I'm pretty sure my sling mount isn't backwards, as it's homemade and that's the way I designed it

"JJH, the sling is a snap-sling from Uncle Mike's" The sling itself not the mount The snapped end goes near the muzzle HAPPY NEW YEAR

Cool

I've seen, held, and shot Rip's rifle in the just before completed phase, and I've played with it (but not shot it) as it is now complete.

I can't tell you guys how impressive it is when you realize it's a built from scratch rifle.

Rip, I'm going to try to design a cool side match for January for you to use this thing.

Great work! I'm certain that if you wrote up a manufacturing process design documenting you did, that folks would buy a copy. I would.

As for the heat treatment, have you checked the hardness with a rockwell tester? Doing it yourself with a torch is quite suspicious! Remember what happened with the guys in Washington. If you don't temper it, you will have brittle steel. It's impossible to really control the process with a torch. Sigh.

I don't want to rain on your parade, but your heat treat can't be that good. At the very least, you should check your headspace regularly.

Best wishes!

Major B,
Thanks

I'm not sure about writing everything down. Thats a lot of writing!
I have described a lot of the work in other threads here though.

You can harden with a torch and yes I've tested with a hardness tester, and tempered, and I do frequently check headspace. (hasn't moved yet, 600 rnds and counting)

The areas to be hardened were heated to 1550 deg. and then quenched in oil. Tempered by heating to 1100 deg.

Quote:

Why? Bear in mind that the whole receiver is not hardened, only certain areas. Judging from the receivers I've tested there is a wide range of acceptable hardness. It seems to me that if a part is hard enough to do the job and not crack then it's good.

I do frequently inspect though just to make sure

I gotta ask...

You tempered at 1100? This is the temperature I used to anneal bar stock prior to grinding...

That's interesting. It must be a weird alloy. I know when I used to make knives (could be different), I would temper around 400ish.

Could you give me any help finding some Blueprints? I was starting with an 80% Century R1A1 and I can not find any prints to complete the receiver. I called Century and they said those are sold as 'curios or paperweights' They did not mention this in their sales ad. I did download 2 different prints, but they are not quite right. Any help would be greatly appreciated. If not, wanna buy a $20 paperweight?

80% recievers

I was curious as to what all needed to be done to your reciever, I have my first metric imbel FAL kit and I am on the road alot, so I am hunting a reciever, I read good and bad on almost all manufacturers. I also called tanner's and they are out of FAL recievers . I couldnt find anyone else who supply 80% rec. so I am hunting to refinish my current parts, and trying to not get ripped off on a new reciever, but I want it to be a good one.

Does anyone know of anybody who has made one into a bullpup, it was a thought of mine to do it with my next one;-)

First off, Welcome to the files. There is no such thing as a "80%" FAL reciever.
The one that was but was from a raw casting. More like 20-30% BTW you do understand you are replying to a post many years old.

If you have a Mill and # of years under your belt you might attempt this. If you want a good one new just go and buy a DSA and be done with it.

The raw castings come up from time to time. Every now and then I look at my casting and look at the Mill and go Nope, not gonna try.

As a metallurgist, I am interested in the heat treatment process. Selectively heat treating certain areas is OK provided you know for sure what temperatures you got. 1550 is the correct austenitizing temp for 4140 and oil is the preferred quenching medium. 1100 F is a good tempering temperature for moderate strength and good toughness. My two questions are:

How did you verify temperature?

and

What condition was the rest of the receiver casting in?

Prefereably it was in the normalized condition, ie, 1650 air cooled. Annealed would also be OK, 1450 slow cool. If it was in the as-cast condition, it is possible that there are some brittle areas due to large grains or un-tempered martensite.

In any event, you did some mighty fine work. Good job.
