Default cleaning old grinding grit

I rebuilt an old surface grinder once, and now I'm rebuilding a 16" chop saw.
Both emitted copious streams of grinding swarf, both machines had lots of
aluminum castings. I remember struggling mightily to get the surface grinder
clean, but this chop saw is much worse. I am sure it's the nature of the sparks,
they must be much larger, hotter and "stickier" coming off that 16" wheel at
3450 rpm. At any rate, they're built up in lots of places and I am wondering if
there's any sort of magical trick to getting off built-up grinding grit off of
aluminum castings.

Best I've found is a chipping hammer, or hammer and chisel.

Steel shot in the blast cabinet. Use with extra care.

Or simply knock off whats in the way with a hammer and chisel..and use
the damned thing.

Or are you pin striping it too?

Pin striping a chop saw? ROTFLMAO!! The goal isn't looks here, it's function.
This is a cutoff saw, meaning it has a fixed jaw for doing 90° cuts. It also has
the capability of removing the fixed jaw, moving the vise's movable jaw to a
different orientation, and using a different fixed jaw surface which is cast
into the machine base. There was so much grit packed between the removable fixed
jaw and the 45° cast-in feature, there is *no way* you can use it as is.

The main wheel guard is a large aluminum casting. It is *loaded* with grinding
grit, packed way up in there. It has to be holding about 20 pounds of the stuff,
and it makes lifting it much harder than it should be.

I think I'll look for an extra-long air chisel and use my el cheapo air hammer.
Gonna be tough on the old carpal tunnel, but that crap has to come out.

pin stripes .. you gotta be kidding! :-)

Air-powered Needle Scaler? Start out gently at first, you don't
want to wail on it at 90 PSI wide open and crack the casting.

Disclaimer: I've never done it, but it should work. Don't spend
money for a new one on my guess, but if you can borrow one I'd try.

How about dry ice ?

Thermal expansion (reverse) might pop off the junk. Use eye protection.
I see lots of possible solutions - had to pick one off the wall!
