Make your own foam grips for drop handlebars

Step 3 A bit more detail on cutting

Here you can see how I used small blocks of plywood on each side of the noodle sections to raise the hot wire above the bed surface so the right amount of noodle would be shaved off of the core.

Cut the noodle into sections with a serrated bread knife. Make each section about 11 inches long.

Roll the noodle section on the bed surface as the hot wire cuts the foam. Go at a slow speed that does not force the wire. Keep the center of the noodle directly over the wire.
