Tantal Build Tutorial Part 1

[John@JCDLESales]

The Polish Tantal has to be one of the easiest builds there is. The barrel is best Pushed Out and not

All Thread Removed form my experience. I have to break this Tutorial into parts as there are just too

many Pics.

Although the Tantal can be assembled on any AK Receiver do yourself a favor and get a Dedicated

NoDakSpud Tantal receiver.

Early And Late HG Take Down Nut And Lever.




Acetone Soak your parts Kit for 24 hours. Look for Cosmoline Hiding in the Trunnion and under the

Rear Sight base. Also in the Ft. Sight . And everywhere else you can think of.




Demill The Trunnion Rivets and punch for a true centering of your drill. I use a Centering Drill Bit and the drill never walks.

Make sure you have the rivets flat before punching and switching to the longer drill bit. Drill Slow with alot of oil.

Demilling The Fire Control Group For Use With A NoDakSpud Dedicated Tantal Receiver. Scribe a line level with the top box fold over and seperate with a small cut off wheel and take off the sharp edges.

*Note the 8th Pic down shows the demilling of the Hammer Ratchet. The metal here is very thin so watch how much pressure you apply while holding it in your vise. Also you just have to just lightly touch with a file or Dremel to take off the Rivet Flange before Tapping It Out with a small punch.










*Note It Is The Pin Half Way Down The Selector Shaft You Want To Remove. NOT The One Closest To The Switch Itself.

[John@JCDLESales]

Clean out the Drilled out holes of both trunnions with an Acetone Soaked Q-Tip. Also Clean your Long Rear Rivets with Acetone also before inserting them for your Squish.


* Note Rivet Bucking Plate Made Just For The Larger Tantal Rear Rivets I Use.







Do The Folder Assembly The Goes Into The Receiver In Gray Park. As well as the HG Spring



Do The Rear Sight In Gray Also White Lettering is Optional



Make Sure Everything is Really Clean Before Riveting *Then Clean It Again


Let The Parkerizing MATURE for 72 Hours before trying to handle or Assemble and keep WET with WD-40 for that 72 Hr. Period. That is you will have to Hit it again every 18 Hrs. with WD-40 or so when it looks like it is drying out or should I say drying off.


Matching Up Part Numbers Is A Must.


Use Never Seize When Pushing The Barrel Back In. Will Save you lots of Headaches.


Pay Attention To Safety Fit.


Bingo Go Test Fire And Sight In.

I couldn't tell from the pictures. Did you parkerize all the parts then rivet or did you rivet then parkerize?

[carrolte]

oh, by the way, looks great.

[John@JCDLESales]

Acetone Soak,Blast,Soak Again,Rivet,Blast Any Assembly/Machining Marks,Soak Again Then Park.

All right, the tutorial.

Great info there John. I like it a lot.

What size grit and what media are you blasting with. Silica?

[Ding]

yeah john,I oughta wait a couple days for the excitement to die down but seems good so far.not much work as copes or whom ever made it easy.No receiver leftovers on it,real clean.I'm using an end mill in the drill press to chop the rivet stubs down,dimpleing them and pounding them out.so far so good.next is the long trunion rivets.dimple them and hope bits stay true..just somethin to do tomorrow..

[Ding]

well,it sure ain't like the galil builds or the krinks,that's for sure..

[Ding]

Ding Underfolder is for another Polish AKMS No I don't use any heat and I have found that supporting the barrel and Pushing the Receiver the best way to to get the barrel back in. You have alot more control lining up the Barrel Retaining Hole With The U-Groove in the barrel itself. Go really slow here as it is fairly easy to overshoot the U-Groove. The Never Seize is your BEST Friend Here and apply very little to both the inside of the Ft. Trunnion and the Barrel before inserting.

*Make sure you are Square and verify several times before the Press In. You can do this by holding the the Receiver/Ft. Trunnion with the barrel just started with a light tap into the trunnion and compare the Hole With The U-Groove. Also compare the side clearance of the Rear Sight Base with the Ears on your Trunnion.

Polish your Barrel Pin in a small drill press with 600-800 Grit and Q-Tip Coat with Never Seize as well as the Pin Holes. *GO Light on the Never Seize as it is a Real Bear to get off of your finished Receiver.

Push Slow and use a bright Flashlight to confirm you are lined up perfectly. When Pushing in the Barrel Pin make sure the Receiver Will Not Roll.

[John@JCDLESales]

For you guys that do several builds or work on other Guneapons here's a Good Tip.

But A Ton Of Hockey Pucks To Use As Supports That Don't Mar

Most big Sporting Chain Stores sell them for .99 Ea. If you have Labs buy twice as many cause when one falls to the floor it is theirs.

[Ding]

I know they are john,but I'm the odd ball of the outfit.I have UFD,kinda like OCD,only worse when it comes to UF's.if I could I would have one on all them..your tutorial is awsome.love the pix..

Val I use 36 Grit Aluminum Oxide for the Blast Cabinet. You can alter the finish by using Blast Gun distance to object being blasted along with regulating air pressure to the gun.

Initial Blast is close and fast to remove old finish. And the 36 Grit is the only way to go on the Polish Steel Mags due to the thick paint used at the factory.

[Ding]

I cannot get the barrel pin out,am goin from left to right.am soaking in wd-40 for now.almost ready for tha parts blast,polished carrier,cleaning rod etc.got a dime holding up a dollar here

[John@JCDLESales]

Ding you might have to start it out with a Nipple Pusher Pin. Just get a pusher pin slightly under 7mm and turn a nipple to fit into a hole your probably going to have to drill into the Stuck Pin say3/16".

Best way to start the hole in the pin is with a Centering Drill Stub so your second drill bit won't walk.




Centering Drill


Another thing Ding if you have to put Big Ass Tonnage on the Pin Pusher make sure it won't Roll. I made a Tantal Jig just for this reason and back it up at the Rear Sight Tower with a step block.

*You should have the Leaf Sight removed here I don't but the Pic is just to show you where to back it up.

[Ding]

I got it flush with the trunion,then went with about a 6mm/3/8'?(been too long to remember) hardened rod to push it but it won't budge.I sure don't want to drill it out.the rod is only 6" long so no bend and it's in a collet so it is tight.I'll get it out,just stuck it in freezer for overnight and will hit the trunion,not pin with some heat real quick to see if that will do it..everything is out but the four rivets and the barel pin,so close..thanx for the info and pics.love the jig..had to order a new drill press,got a milling vise this time too so I can do more stuff...like jigs!!!! and a 249 piecerotory bit set and a new pin punch set from HF..thanx john for the help

[Ding]

finally got the pin out..beer 30 now!!!with a tequilla chaser.

[John@JCDLESales]

Get Another Case To Push It Back In And a Bottle of Patrone and a Big Lime

[Ding]

[John@JCDLESales]

Ding Sure thing for the MB.

Had a slight mishap here this afternoon and set a Chemical Grade Pair of Rubber Gloves on fire with my metal cutoff saw. Like a true idiot grabbed the gloves which then flung flaming rubber onto my Rt. Hand. Nice burns and Joni is pissed I won't go to Emg. Rm. Anywho I'll get them back to you in about a week.

Also do you want them Blasted? No Charge for this.

[Ding]

[Ding]

[John@JCDLESales]

Nice Job Buddy. No actually feels alot better. Took 16 Ibuprofrens yesterday and today only 6. Will be fine in a few. As soon as I get your parts I'll do them and get them straight back to you.

[Ding]

[John@JCDLESales]

Hand is doing fine and just trying to keep it clean where there is no skin. I'll get the parts back to you ASAP No Problem. Haven't been to the blast cabinet since I flamed on but have been doing a Yugo M92 build Tutorial until I scab over.

[jwc0506]

John-great write up! i liked ur sequence with demill..... and the acetone clean up sounds like a good game plan. also -phosphating is something i have to try! i take it that it might even hide slight imperfections a bit more? i would also think it might make for a more durable finish. i used a good moly resin paint but i think if i used the undercoating it would be a bit more durable i would hope? well i got a romie-g i want to do up here soon and i'll have to try out some of this stuff! nice rivet work! t.c. Jim

[Col Sanders]

John, I like the grey park, just wondering what it cost for 1 gun? Don't think it would be very cost effective to try myself. Is it expensive?
