Well as promised here is the lyman tang sight "how to". I will try to keep this as logical and as easy to follow as possible.

First the picture of the tools used. A set of snap ring pliers (to remove the retaining screw), small screw driver (for popping off the lever and lever stops) and a 1/4" wrench (to remove the lock nut).

Now so you can follow me I will give you the terminology that I am using for each part. From left to right in the photo.

Retaining screw
Lever lock
Lever lock stops (damaged)
Dohickie
Cross bolt (notice the dohickie spring in the small hole on the left)
Stem assembly
Lock Nut
and underneath is the base

For the stems that are not properly align, you only have to loosen off the lock nut, adjust stem and retighten. The shoulder on right side and the lock nut on the left side sandwich the stem to hold it in the position to the lock.

Caution on removing the cross bolt (it will come out with the lock nut removed) is that the dohickie will come flying out.

A couple of important notes. On the ring on the left hand side of the base there is a notch on the bottom of the ring. This is what the dohickie locks into when the stem is raised to the shooting position.

The stem assembly has a slit in the stem. This slit must face forward on reassembly or the eye piece will be in backwards. Unlike the Marbles the Lyman stem will only fit into the assembly one way. If this is in backwards, so will the eye piece (I know this one from experience).

Here is a picture of the cross bolt removed with just the locking nut taken off. In this picture you can see the dohickie in place and a part of the spring.

The next group of pictures show the disassembly of the cross bolt. I have removed the stem to make it easier to photograph, but you might still have the locking nut in place and just working on cleaning up the locking lever. The removal of the locking nut will allow the cross bolt to come out, but the removal of the retaining screw just removes the locking lever and locking lever stops.

Here is it assembled.

Now with the retaining screw removed. You can see the dohickie in the notch on the bottom.

The next piece to remove is the locking lever. It goes on with the knob to the outside. You can see it length of travel as it is stopped by the dohickie in both directions.

The last piece is the lever lock stops. This fits firmly around the dohickie. The bumpy edges face the locking lever. This one has some damage to the stops on the left.

Here it is with everything removed from the lever side. You can see how the dohickie is in the bottom notch. The cross bolt only has to come out about 1/8" and the dohickie goes flying (know this from personal experience also).

Assembly is pretty straight forward. The cross bolt has to go in with the dohickie in place. You can preassemble the lever locking side without the cross bolt in place or you can do it in place it doesn't matter. As for alignment I just used one of my other sights to get the right angle and tightend it at that point.

Hopefully this fixes more sights than it breaks!
