OK so I missed something when I searched earlier :o according to this thread metal should not be a problem.
I do have a couple of questions about my setup in particular though. The DC that I have has a 100mm intake. My sandblaster takes a 100mm hose so I was hoping to keep that for simplicity's sake. Also, with the sandblaster moving a larger volume of air is more important than suction, so a bigger hose makes sense. For vacuuming chips off the lathe & mill I wanted to use a normal (about 50mm) hose. Also it's going to be much easier for me to run 50mm PVC compared to 100mm PVC. Considering household ducted vacuum systems use pipe about this size I figured I should be able to get away with it too.
Assuming 50mm ducting is going to work I just have to figure out some way to have 50mm duct and 100mm duct into my seperator. Any ideas?
