Nice! Look forward to seeing your LR3 vacuum table setup. Learned a bunch from your topic, had no idea that MDF could be used as an air filter.
Your MPCNC’s Vacuum table topic, and my want to utilize space inspired me to keep the front open. Open front leaves me with options for storage (see pic), or drop table scenarios or partial vacuum in the future. The middle to rear half is solidly closed, glued and screwed like you’d expect for a torsion box. The front half is different though… Although the ribs in-between the plastic storage containers are also glued and screwed, there’s no front rail. Bottom ply skin is not glued yet, so this setup isn’t a proper torsion box imo, am keeping an eye on deflection will tweak as needed.
