the logs are smooth, they've been stored for a number of years, we're gonna rebuild it soon and I'm just knocking the finish (Varnish; Shellac) off the outside and years of dust and dirt on the inside. The first pad caught a splinter and threw the paper off and the pad hooks made a couple revs on the surface and smoothed out about a forth of the pad. Even a new disk wouldn't stick so I put on a new one and now its getting like the other one except I haven't made any contact with the bare hooks to log.
