ABSTRACT:
An apparatus for abrading a surface is provided. The apparatus has a compact profile and includes a drive mechanism disposed in a housing. The drive mechanism includes a substantially vertical drive shaft rotatably mounted on a first plate and including a drive pulley mounted on the shaft. The drive pulley is rotatably connected to at least one coplanar pulley mounted on a substantially vertical shaft and disposed between the first plate and a second plate attached substantially parallel to the first plate. Thus, use of the apparatus in height-restricted spaces is facilitated.
