A machine is provided for grinding the top surface of an annular body. The achine includes a block which is receivable within the annulus of the body. The top of the block has a central hole. A plurality of rods slidably extend transversely through the block with a first end of each rod extendable into the hole and a second end of each rod extendable from a side of the block opposite the inside curved surface of the annular body. A plurality of arcuate pads are provided wherein each pad has an arc which conforms to the curve of the inside of the annular body. Each pad is connected to a respective second end of each rod. A bolt is threaded into the central hole of the block, the bolt having a bottom tapered portion for engaging the first ends of the rods so that when the bolt is threaded into the block the rods will be forced outwardly to engage the arcuate pads with the inside curved surface of the annular body. A turntable is slidably mounted on the top of the block. A grinding device is mounted on the turntable and has a downwardly facing grinding surface for engaging the top surface of the annular body.

A machine is provided for in-situ grinding of tapered lugs on a hatch, such s a hatch aboard a submarine. A base is provided and a device is attached to alternate lugs of the hatch for mounting the base across the hatch opening. An elongated plate is mounted at its center to the base for pivotal movement thereon. The pivotal plate has opposite ends wherein each end is extendable between a pair of alternate lugs, one of the lugs between one of the pair of lugs being a lug to be ground. A device is mounted on the base for oscillating the pivotal plate back and forth between the lugs of each pair of alternate lugs. A grinder is provided, and a device is utilized for mounting the grinder at one end of the pivotal plate for selectively engaging the grinder with or backing the grinder away from the lug to be ground. With this arrangement a lug can be ground by oscillating the pivotal plate and engaging the grinding means with the lug.
