My DC Sucks
My DC was underpowered but ok when i got it, and had a single hose running to one machine, but when i ran some more hoses with blastgates to a couple of machines, the suction was terrible. I of course put this down to hoses, connections and blast gates adding up to a problem. Then the other day i was reading a posted review on a 2hp from timbecon, and someone mentioned removing the grille on the inlet, so i thought i would check it out. what i found was a big handful of shavings from the only time i had run it with the thicknesser. I removed them and turned it on without any machines on, but all blast gates open. to my suprise the bag half filled within a minute. now its like having a new DC, one that actually sucks. now a lot of you forumites are gonna be saying "well dah", but sometimes beginners overlook the simplest solution.
Thanks Kev.

Had the same problem with one of my DC's I use for the thicknesser and jointer. The grill was blocked. Sidecutters soon fixed that. I know the frill is there to stop large splinters from getting into the suction fan but because of the dedicated use I don't see that as a concern ( This comment was added for the safety Nazis)
If you can do it - Do it! If you can't do it - Try it!
Do both well!

Anyone know if there's any major differences between the impellers on CT's FM-300 DC and their CT- series?
Finally picked mine up after work today and, not having time for any serious woodwork but still wanting to see my money at work, hooked up the floor-sweep and promptly disposed of the last weeks floor-sweepings which were convenient to hand.
Sadly, I forgot about the inevitable dropped nuts, bolts & other oddments in the sweepings until I heard 'em impact the impeller. My first thought? "At least they didn't block the grille!" My second thought? "Maybe it would've been better if they had!" :eek:
Haven't been game to check for damage yet; thought it the better part of wisdom to leave the tools alone and come back tomorrow...

Check the outlet: mine had a grille there too. I've cut off both grilles from my DC, and it works fine. Haven't sucked up a spanner yet!
Those are my principles, and if you don't like them . . . well, I have others.

G'day fellas.
I have the FM300 and the CT001V. One thing to look for is the swirling action in the bottom plastic bag. You can test when closing the blast gates if you have them fitted. As soon as you open the gate, the swirling action begins. It also stops when the inlet is blocked. This usually happens when machining soft wood or when a rag gets into the system (yes this can happen!!). The removal of the grille could cause problems with the rags though. Don't laugh. It happened to me when my back was turned.
Regards
Les

Do you notice any change in the sound of the DC when it's blocked? I'm not tempted to try it with mine yet.
I've been considering building a cyclone for the DC, not being aware that the DC incorporated a pseudo-cyclone. Methinks I'll settle for a seperator, both to prevent larger pieces impacting the impeller/grille and to reduce the need to redo that #@%^$ clip holding the lower bag...

The DC seems to have incorporated a psuedo cyclone. The chips swirl at great speed in the bottom bag.
I think that a separator might be quite handy, but I am not sure of any reduction in sucking power. After all - we want it to SUCK !!

1. The motor is cooled separately from the dust impeller.
2. The maximum load on the motor (and therefore the highest amps) occurs when the motor is pumping maximium air volume. If it is clogged its thus pumping less air so there is less current being used.
