Shop Layout - Would love feedback

[Alan m]

unfortunitly shop layout is very hard to nail down. it evolves with new machinery and with the jobs your doing.. I have changed my layout several times

+1 more vote for vertical plywood storage. The only shops I've ever been in that had horizontal sheet storage that made any sense used a forklift to move units. Or had a auto sheet loader for their cnc.
Have you considered exhausting your dust collection directly outside? If it's an area where the loose dust wouldn't cause a problem, it'll almost double the efficiency of your collector because you don't have to exaust through a filter.
It looks like you're showing a 4" duct to the table saw, which won't allow enough airflow to pull air through the cabinet. Use 6", if possible. It's also nice if you can allow a 4" tee for a retractable saw hood, since some of the dust will leave from the top.
