Step 1: The principle drawings
Step 2: Preparing the pieces
Step 3: Assembling
The thickness of the lever has to be reduced just a little with sanding paper, so it will move smoothly. Then you attach some screws or otherwise carve two hooks to attach the rubber band to.
Drill a 6 mm hole in the turning center of the lever, then attach it to the stock/1-layer piece with a screw. You do it from the outside and the screw must be long enough to pass through the entire thickness of the rifle. (I actually sanded the screw down to mach the thickness)...
Step 4: Paint it
Just a layer of varnish and you are ready to make a little boy or girl the proud owner of a western rifle... Have fun.
