White Oak and other various hardwood 7x9" cut offs are about five bucks a truckload here because the mills are sawing out railroad ties. I've collected some up to 30" long. They're sold for firewood, but I've found the blocks handy for lots of other uses too.
If this thread stays in OTBF it will be lost forever when it falls to the end, not archived/searchable like all the other forum sections. Let's don't let that happen. I learned about post vises here-never quite understood them before.
