Yes, the top covers are almost always cut there, might even call it a design flaw. Don't think it will bother me though , or the side cover missing.
Table appears to be aluminum plate maybe glued down. Haven't decided if I'm going to try removing it or not, don't ever remember using a miter gauge on my old one but do remember having to clean the slot plenty.
I have a 2x48 Rockwell belt grinder that may have to go but I hate to part with it. Need a bigger shop since I definitely have to sell the Hardinge BB4 for space to put this sander.
