Neatness in floor laying....

Okay, at the edges (close to the wall), you can't use the nail gun because there's not enough clearance to swing the hammer. So you either screw in the floorboards very close to the edge or do it through the board and cover the screwholes with plus. This is how Todd did it.

These pics loaded in the wrong order, but here is the finished product...
An unfinished plugged hole (with a spare plug lying beside it.)
Todd hammering in a plug. He first puts glue on the edges, then hammers it in.
Tools of the trade. Todd had saved the ends of boards from the pieces that needed plugs. He took them to the shop and used a drill press to drill these slightly tapered plugs. They get chiseled out, hammered in and then sawed flush to the floor.
