Blasting media question

You are doing this the hard way. But yes there are sieves/wire meshes in specific sizes that are used to determine grit size. These are laboratory supplies. You are better off throwing away all your "grit" and buying the proper stuff, then you know what you have the proper grit that will do the job without damaging the work. I alternate between glass bead and aluminum oxide which are readily available from local suppliers.

Although I *did* get the answer I was looking for, it turns out it's less than practical. I didn't figure that a few screens would be very expensive, and they aren't TOO bad, but still, it's about the same cost as buying a bag of media.

That being said, crushed glass should be fine for things like bolt heads, hinge arms, et cetera, right?
