Well I redesigned my dust collector gantry after I figured out that my original designed limited my ability to do tile work. So I bought the suck-it system hoping for a masterpiece of engineering and being let down with what I received. I love their dust boot but for me the arm is a waist of time. S3XXL + HDZ + 2.2kw spindle = no bueno. I ended up custom making a new one out of steel angle iron and a heavy duty caster. I put the suck-it one on the gantry for a size comparison. Any one care to buy my new unused suck-it arm?
