Opinions of dust collectors, please


#1

Hello, I went dust collector shopping today. I looked around on the
web, perused the usual tool catalogs, only to find that there
seemingly are only two options in a large table top model: The large
Handler 76, available from Gesswien, Frie & borel, etc., and Rio
Grande’s Super Collector. I’ll be using a Baldor 1/3 hp., 2 speed
polishing lathe. Do any of you have an opinion to share?

Thanks,
Ken Weston

Save a dollar…I bought a bathroom exast fan ( 65cfm ) from
the hardware store and some of the aircondition filter material
…exasusted out side…red rough. buffing compound and cotton
fiber gone…cleanest my shop has been for years. …Clyde…

Ken: You might try one of the dental suppliers. Darby Dental comes
to mind they also handle the Handler under the bench unit. I could
supply you with the Vanivac from Vaniman. Really great suction
system and it has a heavy solid waste separating tower to prolong the
life of the filter bags. Nice thing about the filter bags they filter
to about 5 micron or better which makes a nice neat package for your
refiner of scrap and bench sweeps. PS we also do the repair work on
these.

Hello Ken: I just purchased and installed the “Space saver dust
collector system” from Rio Grande, item number 336-400 $590.00.
Instead of buying a new motor and steel hoods, I modified my regular
polisher by making two boxes out of sheet metal and mounted them with
some weather strip gasket inside my polisher at each collection
opening. On the back of each box I cut a hole large enough to install
a plastic sink drain fitting with the middle cut out. From that I used
3 inch rubber couplings to tie it to 3 inch flexible PVC hose. I cut
holes in the back of my old polishing unit to run the hose through. I
used 3 inch PVC 90 degree elbows to turn the hose down through the
holes I cut in my counter top and straight down to the openings of
the collector. I disconnected the blower motor inside my old polishing
unit and installed a 110 volt outlet on those wires and plugged the
new collector into it. Now when I turn on my polishing motor the
collector comes on. I also put a fitting in the PVC so I can run a
vacuum hose and vacuum my shop floor and sweeps. The new collector has
a lever on the bottom that you bang a few times about once a week to
knock the filter bag free of stuck on stuff. I had to cut a hole and
install a 16 X 16 inch return air grill in a cabinet door so that the
air exhausted from the unit could escape well. This has greatly
reduced the amount of dust there is in the air and all over
everything. Let me know if this is something you might want more
info. on and I will get you some pictures. I must say most people
would not do it this way but my old polisher is still good and I
didn’t want to just get rid of it.

G’day; I have a simple suggestion for those who run dust collection
machines which use plastic ducting of any kind to convey the dust.
I see nothing wrong with that, but with fine dust there is always the
possibility of a violent explosion and fire which only needs a little
spark to set it off. That spark can easily be supplied by a build up
of static electrical charge on non conducting plastic ducting. The
remedy is very simple Just run a bare copper wire inside the plastic
tubing, and earth (ground) it at one end. Thus any electrical charge
in the duct will be safely conducted to earth before it can
potentially cause trouble (pun intended). – John Burgess;
