Kapex Dust Collection Modification
« on: January 12, 2015, 03:13 AM »
Hi Guys,

Just wanted to share a little modification I've been tinkering with. So far I'm very pleased with the results !!

Do you think there is a risk that the 'hair' can get caught by the blade and drag the whole dust shroud off?

Did you wait for your partner to be asleep before using the scissors  [wink]

Interesting same idea same as you get around a cnc cutter. Does it work as well as the original rubber one, obviously it must flex better

I certainly did wait peter !!! [big grin]

I made a few of these, playing with the length of the bristles, making multiple cuts at different bevels and angles, and I have no concerns with any interaction with the blade !

I feel it works much better than the original one. If you look closely, the attachment of the bristles is onto the factory shroud.

I felt I could improve upon the shroud, as the larger dust particles always made it underneath the rubber shroud.....this made a huge difference !

I have sacrificial facings on the left and right moveable fence and these extend into the centre to form a zero clearance splinter reducer. I find that the original dust shroud does catch on that and although is deforms itself to get by with no problem it does reduce its dust catcher capability whilst distorted.

I imagine that the bristles do not all distort at once which might improve the overall dust collection.

A nice idea and worth seeing again after a couple of months or regular use. Meanwhile you might like to see whether you can market the idea.

Nice idea.  Where did you find the bristles?

I like it!

If you're planning to sell them, how much? Do you need any beta testers? [wink]

If you aren't planning to sell them would you be willing provide more details, publicly or privately?

very ingenious.  This got posted over on BTP and I thought it was a GREAT idea!

I "upgraded" my axialglide to the kapex boot and it made a huge difference but I REALLY like this idea. 

What are you using for bristle material/holder??  It looks pre-made and then attached to the festool boot but just cut to length?

Nice idea and execution. I have the same issue that Peter  described with the zero clearance  on the fence. I think that this is the fix for my issue.

The bristles in this length and configuration  funnily enough are very hard to come by unless your order 15 miles of the stuff !!!!

We are fine tuning the design, but based upon the interest I'm seeing, we will get a batch of these made up   [smile]

I will get some video of it in action.

The brushes are frequently used in CNC dust shoes and they are available via McMaster-Car at http://www.mcmaster.com/#strip-brushes/=vlslfv.

I have used the same process on many of my tools also.  I have 4" brushes around my tablesaw shrouds and cut with virtually no dust. 
I also did something similar on my Makita sliding chopsaw.  I have been using NGP bust seals as we use them extensively in the commercial door work we do.  I am glad to see there is a source with PVC holders as all of NGP's are aluminum.  I use 1" brushes clipped to my 55 and 75 when I am cutting plastics as even Festools extraction does not capture that mess.

I believe this is closer to what he is using:

http://www.mcmaster.com/#strip-brush-holders/=vlxewl

Look about halfway down the page for "Easy-Cut Strip Brushes and Holders"

And it's cheap - $2.28 per foot for a 1" brush, and $3-$4 per foot for the holder, depending on style. You could easily make two of these (because you have to buy a minimum of a foot of material) for less than $10. That doesn't count your time, of course.

wow,

Thank you, that was a most helpful link.  As I have a need for a similar application on a non-Festool tool, I also did some research and found the material available in several places.  However, your link seems to be the best, both price wise and in ability to purchase in smaller amounts.

Hi guys,

I apologize for not responding more hastily. Yes, the 3 " bristles are readily available, and that's what I used for the first prototype that you see pictured. However, to reach the base of the saw, this had to be attached to the factory rubber boot, which still does not work with a zero clearance fence as well as it could.

The ones I'm putting together now completely replace the rubber boot by attaching the same way as the boot does. This way you have full length bristles, and no rubber boot. This way it can be used effectively with a zero clearance fence.

It was the longer bristles that were hard to source, as 1-3 inches seemed to be the standard.
