Hey Group,

I have and old Wingmaster that I want to hack aroound with and modify for use with 3" shells. My understanding is that the ejector is the only thing that need replacement.

So, I have the ejector and rivets and a "Menck" staking tool. I would appreciate if someone whi has done this could walk me through the process.

Do I only need to remove the front rivet to replace the ejector and stake the rivet in a two stage operation? (ejector housing and then the ejector)

I'm not certain that the "Menck" staking tool provided is correct for staking the ejector rivet(s). Any information foound on this tool says that it's for the shell latch rivet. Can someone please confirm if I can use this tool and if so, a rough idea as to how to employ it.

Thanks in advance!

FWIW, I had Casey at TacOrd do mine. Having seen the front two stage rivit, I don't think it's a job for the timid, as you only get one chance to do it right.

I don't think the tool you show is the right one for the job. I beleive the front rivit needs a hollow rivit punch to protect the ejector spring portion.

I don't think that tool is used for the ejector... is the "point" of it really not a point but actually has a width to it? It looks like the tool used to stake the shell latches in each side at the bottom of the action. They do not use rivets.. the action actually gets smacked and holds the latch in place. Look at your present latches and you can see how they are staked in.

The rivet staking tool is more like a hollow tipped punch. The rivet protrudes out the side of the action considerably and that is held on a hard flat while you rivet the other end of it from inside the action using the hollow tipped punch which helps hold the assembly as well as forms a nice rounded head on the rivet. After it is all installed you have to remove excess material on the protruding end on the outside of the action and then usually refinish and blue the action.

You need to remove the old ejector spring and then the ejector (U shaped channel that the spring sits in).
Both need to be 3 inch type parts.
New rivets must be used in the process. They will protrude slightly on the outside of the receiver as they are blended in during the polishing process before the finish is done to the receiver.
The ejector is rivetted in first using the plain rivet at the rear and the stepped rivet in the front. Once the step on the front rivet is installed, the ejector spring is put in and the tip of the front rivet is peined over to hold the spring in.
You should have the proper tools as indicated in the above posts.
The tool you have is NOT the tool to use for this.
Good luck!
