ABSTRACT:
The resurfacer includes an arbor attached to a grindstone. The arbor may be connected to a power tool to rotate the grindstone at a high rate of speed. A housing is disposed over the arbor and connected to a threaded adaptor. The size of the adaptor may be varied to conform to the valve being resurfaced. The adaptor threadedly engages the valve at which time the grindstone may be forced into engagement with the valve gasket seat. Also, small windows are incorporated in the adaptor walls in order to allow viewing of the grinding progress and venting of the grinding area to prevent pressure build-up.
