How to Build Skateboard Grinders

Skateboarding is a growing sport throughout small neighborhoods and big cities with new skate parks popping up every year. Save money and travel time to the skate parks by building your own skateboard grinders to keep at home. A steel, welded, square or round rail grinder will hold up to any abuse that an avid skater puts it through to learn and master new skating tricks like a 50/50 grind, rail slide or Smith grind.

Instructions

  1. Steel Square Grind Rail

    • 1

      Purchase steel tubing from a local vendor. Choose square steel tubes that are 2 inches by 2 inches square, with a 1/8-inch to 3/16-inch wall thickness, known as 2-inch square tubing in steel shops.

    • 2

      Cut two pieces of square tubing measuring 6 3/4 inches long for the legs and one piece measuring 6 feet long for the rail.

    • 3

      Cut two feet for the rail made from 3/16-inch-by-4-inch-by-1-foot plate steel.

    • 4

      Mark the center of the feet on the plate and weld on the legs perpendicular to the feet.

    • 5

      Place the 6-foot tube on top of the legs, with the legs 9 inches from each end of the tube. Level the tube and weld it on to the legs.

    Steel Round Grind Rail

    • 6

      Purchase steel tubing from a local vendor. Buy round steel pipe with a 2 3/8-inch outside diameter and a 1/4-inch wall thickness, known as 2-inch OD, Schedule 80, black steel pipe in steel shops.

    • 7

      Cut two pieces of round tubing measuring 10 1/2 inches long for the legs and one piece measuring 6 feet long for the rail. Grind a semicircle notch into the tops of the legs to make it easier to weld them together.

    • 8

      Cut two feet for the rail made from 3/16-inch-by-4-inch-by-1-foot plate steel.

    • 9

      Mark the center of the feet on the plate and weld on the legs perpendicular to the feet.
