So, I'm trying something out, I did a light wipe of shellac before machining. I'm still messing with infilling, one thing I've found is that the haze really stains the matte black paint on the dotcom panels very easily. Then I did another one with just wd-40 that worked pretty well. I was mostly able to clean it up with a tooth brush and mineral spirits though, kind of a pain. I tried a few different types of lubrication, wax didn't really work well, the very fine black chips from the paint got stuck in the engraving. I added 2 deg ramps and a finishing pass, much much cleaner results. I think the results are much better, and the job seemed to go smoother overall.
I ran a some cuts yesterday and tonight implementing a few things I've learned as far as setting up tool paths. Second I bought this "home made" dumb bell from a welding/metal supply shop, it does a great job of holding down and flattening the panels while the glue sets up. I've made some upgrades to my rig, not the sexy stuff but serious improvements.įirst a welder buddy gave me this machine table, it is WAY more stable than the work bench I built out of 2x3's (which isn't a piece of junk by any means)
