i wrapped a teenager around a foam block once. ;-]
seriously? Pam Wedd had a real good series of articles on sanding, varnishing, painting. they were in the Journal although I can't recall the nos.
One of the hints related to sandpapaer itself---- fasten a hacksaw blade to something solid, like the door frame. You can slide the sandpaper under and tear it off just like waxed paper. Then get it to where you can fold it in thirds. Thirds keeps the sandpaper grit from touching itself and stays sharp when folded that way. then go cross grain eek. but with fine 220 320 400 whatever you can live with. then "heavenly" varnish.
I think she sanded the planking with somthing more fine than was used on the ribs. If memory serves.
