I have always wanted some brass knuckles but didn't have the resources. I finally decided to make a wooden pair.
Step 1: Measuring.
First I measured my wood to the desired length.
Step 2: Cutting.
When I had measured my wood I cut it. (Apparently I didn't cut it very straight.)
Step 3: Sanding.
After I cut the wood, I sanded it.
Step 4: Shape.
Next I drew the shape of the knuckle.
Step 5: Shaping.
I used a jig saw to cut out the shape as well as the holes.
Step 6: Sanding 2
Once the knuckle was done sanded and shaped it with a grinder. (I don't have a belt sander.)
Step 7: Staining
Finally I stained it with, Golden Pecan 245. Here is the finished knuckle.
