Nice idea on the switch. But for my little bandsaw kept in the shop, a simple sign would help. Maybe attach it to a short wire so I can flip it away without losing track of it. I think you should suggest this to Laguna.
I went to Laguna's web site and submitted a message to customer service suggesting they add a stop switch on the blade tension lever. No reply.
“We should be careful to get out of an experience only the wisdom that is in it and stop there lest we be like the cat that sits down on a hot stove lid. She will never sit down on a hot stove lid again and that is well but also she will never sit down on a cold one anymore.” - Mark Twain
