Companionway Slide Runner Edges | Polishing

I can tell we are approaching the final stages of the build when I start to write posts about things which are really finishing activities - maybe even snagging.

Cleaning up the runners for the companionway slide is one such activity. I wanted to do this before refitting them to the slide, which is imminent.

The runners are made from a hard and slippery material called Star Board - honestly - and they work just fine but their outer edges show blade marks from when they were cut. Which I dislike.

So I set about removing the marks with the sander, using successive P180/220/280/320 and 400 grits.

Like this.


Then I wet sanded the edges with a P400 grit until they were a smooth, matt finish.

Like this.


They turned out really nice so I set them aside to await installation.
