Basics on Sanding

[Yellowhouse Sam]

No one wants rounded corners where the buttplate interfaces, the wrist with the action or anywhere the wood & metal mate up.  Its easy to maintain this on a flat surface by using a wood block, but what do you fellas favor for backing on contoured or rounded surfaces?

[Delmonico]

One of those flexible blocks made for that, you can get them at any place that sells autobody supplies along with far better rigid blocks than a hunk of wood.
