Hi AV8R,

no, the parts came from Horst Reinecker from Germany. He is a maker of replica luftwaffe aircraft parts.It is his former webshop:

Thank you for the pictures. But I think that I have already downloaded all the KG13 pics from the internet:)

There is one part of the stick what is still quite mysterious for me. To keep the trigger in firing position there is a plunger here:



Unfortunately I don't have information on the specs of this part. What is its shape, what are the dimensions of it?
If you could take some macro pictures and make some measurments for me about this part that would be fantastic.

cheers

This pointed part is one "pressure ball" (dont know correctly name), like:


Thanks to Inigohe from Escuadron69 for this picture.

When you flip trigger down, this ball lock in this recess point in "ready to fire" position.



When you need need put trigger in safety position, just push the trigger forward with your finger, the ball leave the recess point and the coil spring do the rest.

Hi Sokol,

thanks for sharing the info. I am afraid it is only partly true.
I inspected a bit my parts and consulted with Herr Reinecker, and I think I have the solution.

It is true that a sping plunger hold the trigger in a firing position.

First of all the recessed point you indicate is on the top when the trigger is locked in "armed" position (so it is useless), but there is no "recess" point needed on the trigger at all.
It would be sily solution, becouse it would also lock the movement of the trigger toward the firing button.
The engineers at Argus were very smart guys. They did it like this:

There is a ball pressed by a spring toward the trigger as you showed as well. But the ball is blocked from falling out only by the trigger itself.
They made a path for this ball around the shaft of the trigger.

You can see, that the ball runs freely around the trigger shaft but there is one slope with an edge to block it. When you "arm" the trigger you force the ball over this slope. The edge will hold it until you force it over back again. But you can move the trigger freely towards the fire button.

Clever, elegant and simple. German engineering:D

Nice.

My thought was based on observation of pictures from Web, since I never saw a real KG-13, and lost the opportunity to observe closely his Russian version on Mig-15 in local museum storage.

These pictures show this slope very well:

Thank you.

BTW - I dont find prices in Aeroart page, is need email asking?

Sokol1

Wow, I haven`t seen these pictures. I like the one with the special double button pushing trigger:)

You should mail for prices. I can tell you they are not cheap:P

The double button version is KG-14, used in He-129, early FW-190...
The lever in right side (front view) select Weapon1, Weapon2, All.

Hi Pit builders,

Happy New Year to All!

After a longer brake I worked a lot today on the steuerknüppel. Now it realy starts to look and feel like a KG13:)
Today I installed the trigger mechanism. It was the most scary part of the whole project, and i am very happy with the result. There was a lot of measuring, trying before every single hole drilling, but it was well spent time.
The mech. works as it should. The torsion spring holds the trigger in safe position, and the ball with the push spring keeps it in firing position. With a little push it jumps back to safe.

On the pictures the trigger shaft is not fully inserted and the spring is not trimmed. I will do it only at the final assembly.

I also mounted the junction box and the cable holder.

And the pics:

This is really comming together. Thanks for the update!

Cheers!

It's looking really, really nice. Great attention to detail.

What are your plans for the stick base?

Wow! What a great piece of engineering.

How did you manage to crosshatch the trigger padle ? Was it cast like that or, did you do it manually ?

Well done anyway.
