How to add flints to your Skate Wheels
I am not a skater or skateboarder so I can neither confirm nor deny these instructions. Install at your own risk.
Drill bit size 5/64.
Only drill the holes no longer than the width of the flints which are roughly 1/4 inch. Creates holes in a zig-zag pattern
Use a point like a Phillips screwdriver to push the flints into the wheel. The harder the wheels, the easier they are and pushing in the flint.
Position the side where the flints are on to the side the skater uses to powerstop or T-stop on their skates. Now when you stop with your wheels, the sparks will happen
If you have additional suggestions or instructions please feel free to contact me!!!
