Abstract
An apparatus for sanding a work piece is provided which includes a mounting surface for abrasive strips and has an axis of rotation. Several of these strips are oriented radially with relation to the axis and laterally to themselves and at least a portion of the strips are surfaced with an abrasive material. These strips are optionally attached to mounting sleeves having a first elastic sleeve adapted to be fitted over the mounting surface. The apparatus preferably includes at least one telescopic housing. Within the housing is a drive shaft including a flexible drive shaft portion and a telescopic drive shaft portion. A motor drive system is also provided. A pivot mechanism is also provided to pivot the drive shaft and the axis of rotation of the apparatus.
Claims55
An apparatus for sanding a work piece comprising:
- a cylindrical mounting surface having an axis of rotation and a plurality of strips disposed radially with relation to said axis and laterally to themselves, at least one of said strips having a front face comprising abrasive grit material such that sliding said front face over said work piece sands said work piece, and said strips being laterally and circumferentially spaced apart from each other,
- an annular cylinder assembly, to which said strips are attached, adapted to removably slide fit over said mounting surface.
An apparatus for sanding a work piece comprising:
- a mounting surface having an axis of rotation and a plurality of strips disposed radially with relation to the axis and laterally to themselves with at least a portion of said strips comprising abrasive material,
- a motor drive system,
- a drive shaft including a first flexible drive shaft portion and a second drive shaft portion,
- a third drive shaft portion and keying means associated with the second and third drive shaft portions,
- a first telescopic housing,
- a second telescopic housing,
- at least one bearing between at least one of the housings and at least one of the drive shaft portions,
- a lock for the telescopic housings.
