Anyone have a place to by 6” scotch brite wheel for bench grinder? The one I purchased from McMaster did not last long.
A grinder is too fast for making the scotchbrite last IMHO. I chuck mine in a variable speed standing drill press and so far one has lasted me thru my entire build - year 5.5 now......I dont know what speed its on, but its probably no more than 500-700rpm - not super fast and for sure not even remotely as fast as my grinder......
Since the health issue was mentioned, I would like to ask about common practice around RV builders . Aluminum particles are getting more and more in the focus as possible health hazards. Also, conductive dust inside electric stuff inside the workshop worries me.
What do you do about it?
Unless, of course, you are painting with product that requires a positive pressure air source.
Note the MSDS data sheet on the paint you plan to use. Compare it to the respirator performance. There are common chemicals in a lot of the paints we use that ARE NOT filtered by a run of the mill respirator...
