If you have assembled blocks and they are square, how much do you trim them? Does it depend on the size of the block?
I recently made a set of 13" blocks and only trimmed those that were off by 1/8" or more. It saved a lot of time to not trim the ones that were only off a few threads but I don't know if it will lead to too much inaccuracy in the finished top, which is not assembled yet. My previous top had 3.5" blocks and those I trimmed every block and the top came out square/even.
