There's a certain element of risk buying auction guns you cannot inspect. This one bit me. It is a first pattern Aydt from Clark Ehler's collection and scratched an itch I've had for too long. Unfortunately, the auction description failed to disclose that the hammer spring was missing. Compound that by the fact that the spring required is different than those documented in Alte Scheibenwaffen books. My gunsmith had a go at it by adapting a Winchester High wall spring on a perch which is shown in the photo. It imparts too little force by the time the firing point reaches the primer. I'm looking for someone who can make a proper spring for me so I can shoot this rifle in our local competitions. Tom

We have been talking about it through PM’s because when he saw my post, thought the same as you.  Before I would attempt it, I would like to see what it was suppose to look like.  But, if it is straight, like the one there now, and it’s just formed correctly or not strong enough, it would not be hard to make.

I’m not sure what that spring did on Tim’s rifle, but thought it was for retaining the forearm.  Something like a sxs shotgun uses.  Maybe Tim will see this post and explain what it does.

The spring I made was a really stout one.  It would take a real man to cock a hammer if it fit.  As simple as that spring looks, it was a tough one to make.

In Bavaria where Aydt rifles are used often, all Aydt owners always have spare springs in their kit. Aydts are known to break springs. I've had two break. I've made several and while not difficult to make found them difficult to harden and temper. I do not recall ever seeing an Aydt with a spring attached with a screw.

Will post pictures of my Aydt breech block and spring. 

Bob, they have an internal hammer.

That spring isn’t any where near as substantial as a main spring in an American made rifle!

What does the springs loose end bear against?

Looks pretty simple!

Tom’s gunsmith must have drilled the hole for the spring he installed.

The pointy thing on the hammer is the hammer sear. As the breech block rises the intermediate sear catches the hammer sear very similar to a Winchester single shot and rolls the hammer back into the cocked position. 

The end of the mainspring bears against the pointy thing on the breech block at the pivot point. When the trigger is pulled the kickoff jumps up and hits the intermediate sear releasing the hammer.

Looks like a punch mark. 

Had to take the Aydt apart to make sure I was describing it correctly. Man did it need a cleaning. Relearned the assembly sequence. Goes together but one way. First the intermediate sear, then the breech block and then the lever.

A gun got cleaned.....
