Barry,

I use the Cool Blocks on my Delta 14" and was curious if you "file" the back
of the blade as some have recommended especially when using the Cool Blocks.

I'm one of the "filers". G I use an old Arkansas stone or grinding wheel.

I don't put the blocks right up to the blade but rather set them about the
thickness of a piece of paper away from the blocks.

Why? Cool blocks are designed to be run close, the gap is typically
used with steel blocks.
