Woodshop Tip #291: Always make sure that the collection bag is securely attached to the dust collector before you turn it on. Possible downsides include:
1. Every surface of your woodshop being covered in a fine layer of sawdust.
2. A slow moving cloud of failure drifting towards you with no mercy.
3. Leaving sawdust footprints on every floor you walk on for the next half hour which makes everyone super pleased with you.
