Just a few recent pics of the planking job, in progress. Again, this is the 5/16" thickness Home Depot pine "V-groove" planking, I believe the brand is "Pine Ridge" (Netherlands), though I can't find much info about it on the web.
Again, I would have preferred a thicker planking, but the roof system is already nearly overloaded at this point, so we wanted to use the lightest stuff possible. We will be covering the collar ties also with the planking and adding assorted pine trim moldings. Lower walls will be covered in bead-board type plywood which will be painted. Then the first 32" from the floor will have thick pine planking with a little shelf above. Will post more pics as things shape up.
