Caster Board for Scrubbing and Floorwork
A board for use in work that requires tedious kneeling, as in scrubbing, repairing of sidewalk lights, and similar work, may be made as follows: Procure a board, ⁷⁄₈ by 10 by 14 in., and pad it with a section of carpet. Place three casters under it, two being set at the rear and one at the front edge. If desired, small strips may be nailed at the sides to prevent the knees from slipping off. Such a device enables the user to move along the floor easily without injuring the knees.—R. S. Matzen, Fort Collins, Colo.
