Void pic? I wouldn’t fill a void with epoxy to save weight. Aluminum butt plates are easyIt came off with a heat gun and a putty knife.
Now the problem is filling the void, it is foam filled and I need to keep the weight down, so I'm thinking epoxy and a very lite aluminum butt plate.
I'm going to try making a plate out of 1/8th aluminum and then either gluing or screwing it on.
Any suggestions or thoughts?
