I guess I do things a bit different. I have a buffet table with a soild mahagony door that is very flat and have been using the same side since 1992. When I am done building I rest my palm sander on it with 100 grit and very lightly sand in case there are any bumps from glue etc. I also have a long bench going down one side of my shop with solid doors and 1/4" mahagony on top of those, can you say flat, total of 24' of work bench when you can find it!!!![] I have been using pins since Moses was a Corporal in the Army and still do, work fine for me.
