I purchase this Makita 9403 belt sander in order to sand down a redwood deck that have be paint with latex that be now peel in many area . I soon notice that the dust collection bag be not collect very much dust . when I remove the cover on the sander for the dust passage I find the passage quarter very narrow and plug with sand debris . connect a powerful shop vacuum to the sander dust tube -lrb- bag remove -rrb- while sand also prove to be futile as the vacuum be not powerful enough to unplug the debris in the passageway . soon after I start sand I notice deposit build up on both roller . the deposit be under the sand belt and mainly on the front metal roller . the deposit form in tenacious clump as high as 3\/16 '' . I have to chisel they off the roller and use lacquer thinner to remove some of they . as the lump gather on the roller the belt would move laterally against the frame and disintegrate . to avoid belt disintegration one have to frequently stop the sander , remove the belt and chisel off the deposit . this get old very fast as it seem I be devote more time to sander maintenance than I be to sand . I finally put the Makita aside and dig out of the garage a Craftsman `` commercial grade '' 4x24 belt sander I purchase at least 20 year ago . it may or may not have be make for Sears by Porter Cable . the Sears sander be a dream compare to the Makita . I do not experience deposit buildup on the roller and do not have to replace belt frequently . I intend to put the Makita sander up for sale as I will not waste anymore time use it . I first attempt to purchase the tool from a Amazon subcontractor who claim to have one unit in stock . I call the subcontractor and ask they to make a warehouse check if a unit be actually in stock . I be tell the warehouse man have the tool in he hand . it turn out to be a brazen lie and waste a lot of my time . I find it amazing that Amazon leave I to deal with the subcontractor . the subcontractor be they agent not mine .
