I have a couple of questions.

First I'd like to get a blast cabinet. Are the better ones with included
vacuum systems such as from eastwood safe to use indoors. How much leakage
is there. Can the risk be minimized by using different media. I have two
young kids and would not want to take a risk.

Number two. I've read that carbide router bits can be used on aluminum
(6061 in this case). Is this true. Also do I need to use a speed control
on the router to slow it down or can it run full speed.

Thanks In advance
