Thanks. It does. The number of poor videos out there on youtube is not to be
believed. I'm so tired of seeing someone include 30 seconds of their power
band saw cutting a piece of brass off the stock. Or the head mounted camera
that weaves and bobs all over the place.
One of my concerns, as was already mentioned, is atomized vapours in the air.
Once I finish the last little bits of my CNC conversion I can look at adding
fluid and vapour shielding. Don't think it will ever be enclosed like a HAAS
but enough to keep the overspray off a concrete floor that is already in bad
enough shape.
Then I could just switch to flood since the mill came with it. But already
chips are found a fair distance from the machine. Droplets go further and the
mill really needs a COVID-19 mask to keep it's droplets to itself.
John
