Here's a summary of the suggestions I got back from my off-list inquiry about graphite machining: --Cover the lathe rails and bed. Mount a thinshop vac extension head as close as possible to where the bit is throwing thecutoff, such that the tip of the vac head is following the bit. Add generalforced ventilation around the lathe and into open air to keep the dust levellow. -- Build a water trap. Run the vacuum source (small water-capable shop vac) into a 5-gal bucket w/ lid and fitting for hose which draws above the water line. Fill bucket half-full of water and a few drops of liquid soap. Run the working hose into the bucket but extend the fitting attached to lid BELOW the water line close to the bottom of the bucket. The graphite dust collects nicely this way w/o much of a mess. But, expect it to be noisy. -- Machining tip: Slower revs and deeper cuts will place more stress on the material (which can be flakey at the best of times), but produces larger chips that aren’t as dirty as the finer stuff. -- Also suggested: “squirt motor oil on it once per pass, and clean any residue afterward using isopropanol.” HTH!
