As I posted below I have completed a 70-80% receiver blank by century, I did this build by hand tools, these included a dremel, drill (cord), series of files-flat and round fine to bastard, levels, taps, cutoff wheels(stock up), grining stones, heavy vise. no milling machines no lathes or drill press. blueprints and downloaded posts by others from roderus
I will post the pictures in a few days, I have not cut the charging handle slot because I may relocate the charging handle.
this build should fire and feed fine. I am going to the range this week with a sub-caliber device 32acp in 308 adapter to fire function test. then the following week weak reloads very weak reloads
I wonder what RC the recievers on the originals were hardened too. That would give you a good place to start on the hardening process. I happen to be a member at Roderus, I shall check out the work.
As an owner of many 308s, one being a DSA FAL SA58. I can only say that 36 gr of 3031 (assuming your using a 150gr bullet) that won't cycle the action is only slightly hotter than a 30-30. The 308 comes alive at much higher velocity. Might a Winchester 94 have been a less expensive venture?
CK I am calling you a liar in Public on this website for all to see
you are the troll here and a new member here at that
you owe me a apology troll
again for others if you want pictures e-mail me. at Captainjack692@aol.com, if someone would be kind enough and technically able to upload them for me that would be appriecated
I finally pinned in the ejector block and mag release today, the mags needed for these 70% receivers is the inch not metric receiver. I am off to the range using 36grs of 3031 with 147 gr gi pulled fmj, once the gas system works flawlessly I will tap the bolt carrier and modify the top cover
Thanks one million. I have a few more showing the ejector pins and mag release screw. I fired 5 rounds last week they were 40gr of 3031 relatively wealk rounds. next I will use military rounds for gas function
these are the same pictures found on the roderus site(you must be a member and log in to see the forum) also on weaponeer under FAL
I have removed the JB weld I used to help the feeding ramp, now that the mag locks into place rounds feed out of the mag into the chamber without any problems
to the nay sayers and non believers I say get a life.
Sprat, I think it shows a huge amount of skill and patience to pull that build off. Good job. My comment was only to say it's time to get that bad boy heat treated. I did not mean for my comment to sound like a naysayer towards you.
Sprat - Nice build, right out of a 3Rd world country - lol - we might be closer to that than most can imagine, gas food & everything else. I got an Imble Tapco fal receiver years ago.
I'll have to dig it up and take a closer look at it. I helped a friend build one with a 100% receiver. Gun plumber made it easy. The only hard part was the locking pin if I remember
right. We had to use dry ice & heat to get it in. You should see the Thompson 28 build at Beltfed - Others said it could not be done, but see who got the last laugh
.:cheers:
P.S. There was a place selling raw AR 15 receivers and had info on heat treating
in SG news at there web sight. PSS. ( Don't let the want-to- bee's bother you )
Need more Pic's Xfrog
I'm actually kind of surprised your rifle is holding head space with no heat treat on it. (..is it maintaining head space? are you checking to see if it's growing with a complete set of gauges?) I've fired less than a mag on a raw receiver and had the head space grow considerably (not something I would recommend) You don't have to heat treat the entire receiver like DSA... I think the Austrians just spot treated their receivers. The area that takes the beating is around the locking shoulder. The shoulder itself won't deform (because it's heat treated) but the receiver in that area won't hold up.
I'm not here to preach or anything, either way it's nothing to me personally... just throwing out some info I've gained. Also, I've had an FAL fly apart on me due to bad ammo... and I can say definitively that it's not a recommended experience.
Someone said something about a receiver stub... I have some pics if that helps.
The original Aussie receivers have some issues with stretching after many rounds. This is because the receivers are only hardened in certain spots for wear but left soft for most of the receiver body to prevent cracks. The Aussie and Canadian receivers are "flame cut" instead of forged. I think this method is similar to machined billet. I'm not sure how the British receivers are formed. The Belgian receivers were originally forged from a steel similar to 1060 steel. The last Belgian receivers were cast from a steel similar to 4140 steel. The original design wouldn't allow full hardening without being prone to cracks. The newer cast receivers are made of a steel that is less prone to cracking. FN said they were able to afford upgrading the steel for the cast steel receivers because they could recycle the bad ones on site and just cast the steel again. FN was trying to compete with the stamped and welded H&K rifles in price. Early in the FAL development they made a lot of upgrades but near the end of production they cut costs of a lot of things. FN even contracted Argentina to make rifles and parts but marked FN for Belgian sales. Brazil decided to go a different route and develop their own cost cutting and compete with FN and Argentina for sales.
I & several friends are building Chilean kits on the last of the ORF receivers to be sold, but they are 100% FFL items & not a finish it your self deal. A person who can finish a 70% receiver that is not heatreated, to completion, with no machine tools is a dedicated person IMHO!
thanks for the compliments. I did cause no one had done it before with hand tools others had done it with milling machines or welding part together. I don't own a bridgeport so i did it the old fashion way
like my ar-15 0% dsa reciever I did it with a drill press and sears hand drill
I posted this build on FN FAL files some clown named radio shot me down and berated me so I said F*ck him and posted on WG and here and roderus
in addition C J had said so falsehoods about me and my skills ( J/O) check CJ 's post he is not a builder or major contributor but a jealous member I can out build him and 90% for the members here and on weaponsguild
i will also note several folks built up functioning rifles with these on CNC and one guy welded the front stub to the cast before i did my hand build
sorry for the poor quality pic's they are all i have left
also i only used military full load ammo once with this build i always used 32 acp caliber adapter and weak 308 reloads
I never heat treated the build, I was approched for the build materials and kit I only retain the receiver, great paper weight
