How to Juice Your Baseball or Softball Bat

Shaving a Metal Bat

  1. Pop the end cap off the end of your metal bat. These caps are not designed to pop off so you need to use a pry tool such as a paint scraper or flat-head screwdriver.

  2. Shave the inside walls of the bat with a metal file or lathe. Do not scrape more than a millimeter out of the barrel. You are looking to increase the trampoline effect of the barrel, not make it brittle to break.

  3. Pop the cap back onto the top of the bat. You may need to use force or shave down the rim of the cap. Use crazy glue to seal the cap shut for added security.


  1. Heat your metal bat up. Leave it in the sun for the afternoon or leave it in a hot car.

  2. Place the bat on a surface that can withstand hammer hits such as collapsed cardboard boxes or pile of towels.

  3. Hit all sides of the barrel of the bat several times with a rubber mallet to thin the walls of the bat, much like shaving but with less chance of getting caught. This will age the bat prematurely, but it will have a juicing effect.


  1. Pop the top of the metal bat off as described in Section 1.

  2. Crazy glue several small metal weights to the inside of the barrel. You can use magnets to weight the end of the bat and the magnetism will help hold them in place. The closer to the end of the bat the better.

  3. Replace the top of the bat as described in Section 1.

  4. Swing the bat with extra force due to the added ounces at the end of the bat. This increases power and is referred to as "end loading."
