Equipment

  • - Brad nails (2″)
  • - Drill/driver
  • - Kreg Jig (720 PRO recommended)
  • Miter Saw
  • Brad Nailer
  • Sander

Ingredients

  • - 9 – 2×4×8 boards
  • - 2 – 2×6×8 boards
  • - 2 sheets – ¾″ MDF 4′×8′ (top + bottom shelf)
  • - 4 – 5″ locking casters
  • - 2½″ pocket-hole screws
  • - 2½″ wood screws

Instructions

  • Build the bottom frame: After cutting your boards, drill 1½″ pocket holes into the short pieces. Attach them to the long pieces with 2½″ pocket-hole screws and wood glue to create the bottom frame.
  • Build the top frame: Repeat the same process to create the top frame. Drill 1½″ pocket holes in the short pieces and attach with 2½″ pocket-hole screws and glue.
  • Assemble the legs: Drill 1½″ pocket holes into the 2×6 leg boards. Attach them to the 2×4 leg boards with 2½″ pocket-hole screws and glue. Repeat for all four legs.
  • Attach legs to the bottom frame: Position each laminated leg at the outside corners of the bottom frame. From the inside of the frame, secure with 2½″ wood screws and glue. Make sure the bottoms are flush.
  • Add the top frame: Flip the bench over and slide the top frame onto the legs. Attach with 2½″ wood screws and glue, driving through the legs into the frame. Keep the tops flush.
  • Add feet: Attach 5″ 2×4 feet blocks to the bottom of the frame with 2½″ wood screws and glue. These give a solid base for the casters.
  • Install casters: Center and attach a locking caster on each foot using the hardware provided. This makes your workbench mobile and sturdy.
  • Add shelves and top: Apply wood glue to the frame edges, then lay the MDF panels on top and bottom. Secure with 2″ brad nails.

Notes

NOTES:
- Standard finished height is ~34–38″. Adjust leg length using this formula: desired height − caster height − top thickness.
- For extra strength on a 4×8 build, consider adding center stretchers to reduce sag.
