We just got back from the show and there was a lot of cool things. Nice summary up top. One of my favorite was by IQ Power Tools. They have a tile saw that doesn't require any water and creates no dust, well it's 99% dust free.
Welcome to the forum and the crew. That sucks about Craftsman. After I get burned by a product or company, it's very hard to go back. I don;t have much experience with harbor Freight but I know some guys on here have talked about those hand tools.
Does the motor turn off also? If the motor is still on, then check your blade and arbor. The blade might not be set properly in the arbor or the blade might have a different arbor setting. Some art diamond shape and others are round.
