Build Steps

One card at a time — your progress is saved.

01Step 1 of 6

Remove the caster wheel

Unbolt and take the wheel out of the swivel caster's fork. You'll reuse the fork and its axle to hold the PVC pipe — the wheel itself isn't needed.

TipKeep the axle bolt; it becomes the pivot pin for the pipe.

02Step 2 of 6

Cut the PVC sleeve

Cut the 2" PVC pipe to 12" with a miter saw or hacksaw. Deburr the inside of the top edge so the barbell slides in and out cleanly.

03Step 3 of 6

Drill the pivot hole

Near the bottom of the PVC, drill straight through both walls with a 1/2" bit (size it to your caster's axle bolt) so the pipe seats in the fork where the wheel was.

04Step 4 of 6

Assemble the pivot

Set the PVC into the caster fork, line up the holes, and run the axle bolt (or a lag screw) through the fork and the PVC, secured with washers. The pipe should tilt up and down on the axle and rotate on the swivel plate.

TipSnug, not over-tightened — you want free movement in every direction.

05Step 5 of 6

Mount the base

Screw the caster's top plate to a ~12"×12" scrap plywood board with the lag screws and washers (set the board in a corner and weight it down — no drilling needed), or bolt the plate straight to the floor.

WarningIf you bolt into a concrete slab, check for radiant-heat lines or electrical conduit first.

06Step 6 of 6

Load a barbell and test range of motion

Place the unit 18–24 inches from two walls for clearance. Slide one barbell end into the PVC and run a few unloaded reps in each pattern (press, row, rotation) before adding weight.

TipSet it in a corner so the swivel can't kick the base out from under load.

4" swivel caster wheelThe pivot. Pick one with a wheel at least 2" wide so the PVC seats in the fork — the swivel plate gives 360° rotation and the axle gives the up-and-down press/row motion.
