Greetings comrades! May your glass be always full of vodka and the fire of pride for the glorious motherland burn bright in your heart. I am working hard on restoring a RomyG to its former glory, the time when capitalists and bourgeoisie trembled in their expensive baby seal shoes at the barrel of a AK47 pointing at them from the East.
Barrel pins were put to retain barrels in the front trunnion and such a good job did the drunk bearded ladies of Romania, it’s easier to remove pipe from comrade’s Stalin’s mouth.
I shaped a piece of steel to support the ornate shape of the trunnion, while I remove the pin with a chisel and a hammer. That did not work good. In fact I heard the pin laugh at me. I used air hammer and it did not move. I begged, I yelled, I went down on my knees and wept. I told it all about it’s mother, it’s sisters, grandmother and it refused to listen to me.
I had to cover comrade’s Kalashnikov picture while I contemplated unthinkable … actually making right tools for the job! I have shaped a block of aluminum to mate with the trunnion perfectly like a Donkey Kong with Princess Peach. I have created a top plate so that I can guide a chisel completely drunk and can’t see where it suppose to go. Also, the top plate secures the contraption to the barrel, so when my hands are shaking with a hangover it'll line everything up.
Then I approached a 3 tonne press. It has a crevice in the ram which allows to hold steady a tool for the time’s when I can’t. I pressed and bent the cheap Chinese drill bit.
I decided to double the effort by going to a 6 tonne press. I drilled a ¼ hole in the ram to support a piece of ¼ drill bit as the punch. I pressed and bent the cheap Chinese drill bit.
For a long time, a number 3.333333… appeared in my head. I figured that I need to increase the effort 3.33333… times and use 20 tonne press instead.
... yeah, I bent the pin. This time it was 1/4 drill rod tool steel. It pancaked under pressure.
I was desperate. I have offered comrade Kalashnikov an entire bottle of vodka in exchange to the secret to remove barrel pins. I studied the knowledge of web. What made a lot of sense are two methods to remove barrel pins. One was to use a HF vise made by comrades in China, clamp the trunnion with a pin pressing on it, tighten it and hit the vise like a red headed enemy of the people. Then I heard comrade Flintoid speak of hitting the top of the arbor press and it all made sense. As you hit the chisel, it will resonate, slip and otherwise dissipate the energy of a perfectly good hammer blow. I figure that three things must happen:
1. You need a heavy anvil that will not bounce away easily under a strong blow.
2. You need to press the chisel to the pin hard, so that the energy of the hammer blow will transfer elastically straight to the pin.
3. You need to hold entire jig together while holding your glass.
so I have created this contraption. The thing that looks like comrad Stalin's sex toy is the anvil. Two 1/2 bolts secure the top plate which holds the punch that was ground down from the air-hammer.
I sprayed the threads with some WD-47 and tightened ... how you say it? ... the p*ss out of them.
now, I do not kid you. I took one swing with a 4# hammer, a child's toy, and the pin moved. I was so happy, I took the barrel out of the rig and tried to use regular punch. No luck. I got nowhere. Back in the rig, it took few swings of the hammer to drive the pin completely out.
There was something, I don't know what in the hole, it ripped the groove in the pin as it moved out. If you stare at these two images, you will see what I mean in 3D:
This shows you how a bottle opener and a hammer (... and comrad Stalin's sex toy) can hasten the triumph of world communism!
