Kapex dust

[WarnerConstCo.]

Ok.

I purchased the Kapex and the UG cart when the 10% sale was going on.  I should have known something was up for Festool to discount any of it's items.  Seemed odd to me but I took advantage of the savings.  Needless to say, I returned both items 2 weeks later.  Major disappointment in both products. 

This saw is sort of a joke IMO.  Dust collection is fair at best. However, dust collection on any SCMS isn't great. However, the design of the saw just doesn't promote dust going up that crazy, restricted chute.  Oh yea, buy yet another hose.  Forgot to tell you that will help a bit more.  If the Kapex gets 90% with the 36MM hose then my $500 Hitachi gets 85%.  And the new 10" Bosch glide gets 95%.  Sub-fence is mandatory for cutting small moldings or be prepared for flying objects.  Power of the saw was pathetic.  This saw ran like it was on a 14g cord strung across about 4 football fields.  And there wasn't anything wrong with my saw as I compared it to the display model.  Awkward as heck handle design.  Found myself hating the saw more and more each time I made a cut.  At the time I was building 16 recessed panel columns.  Each had 8 panels with a glazing bead.  Setting a stop on my Sawhelper made this simple but constantly getting my forearm/hand/wrist in that weird position was really annoying. 

In summary I absolutely love my Festool stuff and I really wanted to love this saw.  The portability, capacity, dust collection were strong selling points to me.  However, at nearly $2000 with cart I honestly felt like a sucker.  Thank goodness for the 30 day guarantee!  Since then have purchased the LR32 boring system.  This I can't say enough good things about!

Sorry to hear that your second experience ended up being much like your first experience which ended in selling your previous Kapex in the classified section here back in 2012. 

The return period does allow you to see if the saw is to your liking.

The dust created by Kapex is nothing different from other miter saws. It might be getting too technical, but here is something I drawn up to explain it.
...

In general ^that^ is a very good clear explanation. I like your work! [thumbs up]

However there may also be some windage effects like air stuck to the blade and vortex like things happening??
I suspect that a "scraper" around the blade with an air jet could largely remove the remaining swirl that would be mostly the fine dust as you pointed out.

It would either take some empirical work like a high speed movie, or some computational fluid dynamics to work it out.
It could be a great research project for an academic.

My solution to better miter saw dust collection.

I used a old or damaged MFT top for a few reasons. The biggest being a down draft table being installed bellow the saw along with the hose to the back of the saw.

Dont hand out to me for the fancy babied shop. As i spend 40hrs a week on a dirty dust ridden pile of a jobsight. At home i like things neat organized and clean as possible. It makes things feel less like work

What a great idea! [big grin]

It just happens that I have a Grizzly Downdraft table that I haven't used in ages. I was thinking about selling it because the Festool sanders hook directly up to a CT, and I do very little other sanding that would strongly benefit from the table.

[attachimg=1]

This table has a working height of 32", so only 22mm higher than the Festool Kapex MFT. Workable!  It's wide enough, and deep enough to fit the Kapex easily, and the sides fold down, so it would be easy to add extensions. Table width is 31 1/2" and depth is    28 1/2". The Kapex dimensions are 28" x 19 3/4" x 18 1/2".  No problem!

Powered by an impeller with 1300CFM, and then if I also attach the Kapex to my CT-Mini with 36mm hose, I should be able to eliminate virtually ALL the dust....at least I think! [smile]

Glad you thought of the idea, and made me think of a great use for an otherwise unused machine in my shop!!! [thumbs up]

Cheers,

Frank

  You suck Frank. although in a helpful way....... ;D ;D ;D
Jealous that you have that much room to be able to have that table in the first place. Show us your 'rigged' Kapex table when you get done.  Just don't go to great lengths and repaint that Grizzly Green to match the Festool colors.... [wink]

Dust aside, I'm surprised no one has mentioned kick back yet...

The Kapex is the only saw I've ever had that has kicked back on me during normal use. In reality this has actually worked in my favor as it's forced me to use all saws more safely, i.e. wait for the blade to stop and using fences where possible. This in itself has had a knock-on effect of improving dc as well.
