SCMS Improved dust collection

So, can’t afford a Kapex.  And frankly, my Bosch 4410 has done everything I need it to do with aplomb.  The only negative I can give it is the dust collection is not great.  I always use it with a CT hooked up via 36mm hose.  The hose is a nice snug fit.
It’s pretty good, if I’m cutting wide boards, and I plunge all the way, then push it forward (this is correct cutting technique anyways), as it throws the chips and dust *up* and into the throat of the saw’s collection port.

But I’m not always cutting wide boards.  The Bosch doesn’t come with a shroud or anything, so the major problem is that dust can’t find its way up to the throat.   I had an epiphany about retro-fitting the lovely Kapex shroud onto my saw.

The “apron” is listed on EKat as part # 471316 and lists for about $5.

I just sort of ‘hand-fit’ the apron and used a Sharpie to mark the location of the apron’s holes.  I was aiming for maximum exposure, without getting hung up on the fence when the head was down.
I then drilled holes in the aluminum housing of my saw’s throat and then tapped those holes with M6 threads.
Finally, just put the bolts in with a washer, which holds the apron in place just fine.  I think I used a split lock washer.

Dust collection has improved noticeably.  The apron is made out of a very flexible material, but which keeps its molded shape.  It will squish down onto a board for cutting, but doesn’t leave any marks as it drags across.    

I am a happy (and less dusty) camper.   [big grin]

Here you can see the bolts on the inside of the throat.  I only had some 3/4” M6 bolts on hand.  They don’t cause any problems right now, but I plan to replace them with 1/2” lengths.

great job. improving the dc on a scms is the bain of my life. i have tried every thing and no luck. this adaption looks like it will work great on your saw.
 
Looks great wood junkie.  My Makita LS1013FL has a similar chute on the back of it.  Problem is, when hooked to my Fein Turbo I it gets sucked shut.  The part you have listed looks more rigid than the one on my Mak.  I'll have to give it a try.  Thanks for the post.

Hello, just what i'm looking for for my new Bosh 4310. I would really like to get that 'apron' but what is EKat?
 
Welcome to the FOG! Jacobean

EKAT is an online parts listing with diagrams. This is the Festool part # 471316. Which a dealer can get for you.

Ditto.
I will take a look at my Hitachi. I have seen collection cones set up behind the sliding arms, but i don't have room for same.  I have had moderate success with attaching 36mm hose (and also 27mm) to back of the saw, but they keep slipping off.  I like what it shows in the pics and will try that.  With the 8-1/2 Hitachi, there might not be enough clearance over the fence, but a great idea any how.

The only thing in my shop that creates more dust in my shop is my WoodRat. A CMS has just about solved  that problem.

Thank you Seth, looked up online catalogue Festool Canada and USA. No luck in catalogue, but will try with my retailer.
Sure would be handy with new Bosch.

Try the Bosch "VAC 004" attachment - I put this on my Bosch 4410 and Dewalt 745- allowing me to securely plug 27mm and 36mm hoses into these saws from Festool DC
