Abstract : An in situ refurbishing system for viewing ports aboard pressure-tight hulls includes a guide shaped to cooperate with the viewing port and provide a datum axis centered thereon. An axle is rotatably supported by the guide and carries a lapping tool in polishing engagement with the port. Centering guides permit adjustment of the datum axis and pressure means exert a uniform engagement pressure with the lapping tool such that optical quality surfaces may be obtained without extensive dismantling and use of shipyard time.
