Sitka EMC

[Farrell]

Good memory Dale. I believe the one he made up was 24 inches long. I simply figured the longer it was, the more movement would be observed for a given MC change, so I made it twice as long. I simply edge glued a bunch of scrap from an old soundboard and sanded all the finish off.
