( I use a vacuum > chamber to dry filament - even PLA - makes a lot of difference). I have an evacuation pump, but not a ready chamber big enough or strong enough to put a spool in. I'll investigate some big pvc pipe. Maybe that would work if 8" will take a spool. If I can find caps I can o-ring seal. I dried a soggy hunk of maple that way for a gunstock 13 years ago, but had to glue the caps on keeping it better than 27" hg below atmosphere for about a year. Most stable piece of wood I ever carved, plain straight grained stuff with cherry trim. Thumbhole style holding up a cheap TC 50 cal BP rifle, gets the ooohs and ahhs at the range when I drag it out. Also does 1.25" 5 shot groups at 50 yards too. Pretty good for a $200 gun 25 years ago, with my mods of course. :) And a 16GB stick of ddr4 ram was just found on a chair beside the front door, so I guess I shut down and find out if it works alongside the one in it.
