I got the above dust collector (Central Machinery # 31810) as a stopgap while I figure out where my tools will live and what sort of dust system I will ultimately put in. Today was the first day I ran it attached to a machine, and I am having problems.
I connected it via a 4” flexible hose to my G490X jointer. The collector didn’t have any instructions to speak of but it seemed pretty straightforward – put the bag on the port where the air blows out, and the hose on the port where the air sucks in. There’s a preinstalled plastic grate on the infeed port and they included a spare grate, I guess if the first one breaks. It appears to require opening up the whole collector to change the grate.
My jointer is set up to take about 1/16th off, I believe. I’ve got a spiral cutterhead. The small chips of wood that blow through the jointer look like the really thin shavings used with hamster cages, but they’re not “dust”. The problem I’m having is that these chips are not small enough to go through the grating on the dust collector infeed port.
Some chips have gotten pulled through and are in the bag, but within about ten seconds of cutting anything there is a buildup of chips on the infeed port. This drops the air pressure in the hose (though the bag stays inflated) and before I’ve finished passing the board through the jointer I’m getting clouds of chips spraying out of the jointer anywhere they can go. In the instant that the board clears the cutterhead and the guard has not yet popped back there’s a festive little shower of chips that bursts out of the cutterhead area.
Surely this is not normal. What am I doing wrong? Do I need to get a trash can and cyclone lid to let the chips drop down before reaching the dust collector? They’re so light I think the majority of them would go through anyway, and that will run me an extra $50…which starts to negate the purpose of getting the little one for now anyway. To make matters more annoying I am pretty sure I ditched the dust collector packaging already, after testing that the motor worked.
