With the first stamping completed on the Gerat 05 receiver it is now time to complete the second stamping. As you could see in the photos there were a couple of items that needed to be corrected.
With the second set of dies we press in the correct angle for the magazine housing, both in the front and back of the receiver.
The angle is not great but it make a very large difference to proper magazine placement.
This what it not looks like with the magazine installed.
You can see in this picture that the magazine has proper contact through out the entire receiver.
The rest of the second stamping also bent the bottom of the receiver.
Here is a look at the second set of stamping dies.
This close up shows the new angle for the front of the dies.
So today I am back out finishing the second pressing for the second stamping op. More to come.
I hope folks who look at your photographs understand how much hard work and time went into those stampings. They are looking very good. Harry
Thanks Harry. And no people have no clue.
One of my closest friends and my mentor, John, in weapons design and building always has this to say. “It is just stampings.” What he is saying is that people have no idea what it takes to make stampings. The hours of work and the number of bad pressings are enormous.
I may have missed if it was stated earlier, but what material and thickness are you using for the receiver pressings? Pete in St. Louis
On the 05 and 06 rifles we are using 16 gauge for the receivers.
Chuck, I’m loving the updates. Keep them coming. Very interesting project. I’m adventuresome in some of my building/designing projects but I wouldn’t tackle this in my little gun shop.
Fantastic project, very nice to see people producing things like that
How much tons are required to press things like that ? What is the thickness of the metal plates ?
The bigger press that I have is rated for just under a 100 tons. WE are using 16 gauge for the receivers.
Don’t worry about the size of your press. When I saw that Machine Gun Mike Brown was fabricating an UZI entire receiver on a 20 ton press I nearly crapped in my pants! As a GE tool and diemaker I wouldn’t have tried that feat with anything less then a 150 ton press!
