I ORDERED THIS ON 11 28 AND IT WAS TO BE DELIVERED ON 12 13 TO 12 15. BUT I HAVE IT IN SERVICE ON 12 1  14 DAYS EARLY THAT IS AWESOME . I TO MOUNTED A CYCLONE TO IT. THE DRUM IS VERY WELL MADE VERY STRONG IT WILL OUT LIVE MOST OF US. THE ONLY SMALL PIECE OF POOR PLANING ON THE MOLD DESIGN IS THE HANDEL HAS NO INDENT FOR YOU FINGERS TO GRIP. VERY FLAT BUT YOU DON'T CARY YOUR DUST COLLECTOR EVERY DAY . WHEN I MOUNTED THE ORNIDA LARGE  VORTEX I CUT 2  I/2'' PLYWOOD RINGS OUT TO MATCH THE BASE AND BOLT PATTERN SO THE SLITE CURVE OF THE DOME DOES NOT BOTHER ANYTHING, AND YOU HAVE A FLAT MOUNTING SURFACE FOR THE CYCLONE. AND THE RINGS SANDWICHED THE LID. THIS MADE THE UNIT VERY STRONG AND AIR TIGHT. I SURE WISH I HAD THIS SYSTEM 5 YEARS AGO . MY HOME MADE VERSION WORKED WELL WITH 650 CFM BUT IT DID NOT STOP THE MICRO DUST WITH MY 1300 CFM UNIT I USE NOW.  I ALL MOST FORGOT IF YOU ARE USING 4'' LINES AND NOT THE 5 & 6'' IT IS MADE FOR YOU CAN PUT THE 6 TO 4 ADAPTER ON TOP & 5 TO 4 ON THE SIDE . YOU USE A HEAT GUN TOO SOFTEN THE PLASTIC AND THEY WILL TAP RIGHT IN AND LOOK TOTALLY FACTORY YOU CAN'T SEE THE ADAPTER AT ALL . THE BUCKET & CYCLONE MAKES A GREAT TOOL FOR YOUR SHOP WITH OUT SPENDING  1300 TO 2000 $ FOR A CYCLONE COLLECTOR FOR A HOBBY OR SMALL SHOP.
