From Popular Mechanics

For a fun, simple project during your leaf blower’s off-season,
build a hover disc. Just about any blower that pushes out at least
400 cfm will work, but we recommend using a cordless model.

What You Need

  • Leaf blower
  • Half sheet of ¾"-thick plywood, cut into a 4'-diameter circle
  • Heavy-duty shower curtain or poly tarp
  • Staple gun
  • Duct tape
  • Screws, #8 x 1"
  • 6"-diameter circle of plywood
  • Camp or plastic chair

STEP 1.

Cut a hole for the blower tube (it should fit snug) about 8" from the edge of the plywood, then lay the plywood on top of the shower curtain and cut a circle about 6" larger than the plywood, all the way around.

Fold the shower curtain loosely over the plywood and staple near the edge to hold it down. Use duct tape to cover the staples and seal the curtain to the plywood.

Flip the plywood over and place the 6" wood disc (a paint-can lid also works) in the center. Fasten it with six screws. Cut six holes, 2" in diameter, through the curtain, about 4" from the lid.

Flip over the plywood and then remove your blower’s extension tube. Push the short section that remains through the hole. You can use hot glue, duct tape, or small angle brackets to hold the tube in place. Screw your chair down to the plywood through its feet, but make sure the screws don’t go through the other side. Test out your hover disc on a smooth surface.
