I finally setup my grinder with a CBN wheel. CBN wheel is larger and the original wheel guard no longer fits. I see a lot of pictures of people using them without guards. So, that is what I have been doing. However, there is quite a bit of metal dust coming out. I don't want to use my DC as I worry about sparks causing fire hazard. What are effective options to capture dust from grinding tool steel (plane blades, chisels, etc)?
