Kapex to Dust Collector Hose

I am sure it would fit but would you not get better use from the 36mm hose ?  I use mine on the Kapex, OF1400 & the 850 planer.  The 50mm would be to cumbersome on the portable tools.

kdi,

I also think that you would have to rig up an adaptor to fit the kapex.  The standard 27 mm hose fits into the fitting, the.recommended 36 mm hose fits over the fitting.  Therefore the interior end diameter of the 50 mm hose would have to be reduced.

Karl,

I have the D36 hose hooked to my Kapex.  I see an improvement in dust collection over the D27.  That said...

I also see a bit more drag when I slide the Kapex head.  I use a longer D36 attached to my Boom Arm, so the friction is minimized.  Even then, I could feel the increased friction when moving from D27 to D36. 

If you use a D50, you'll see much more drag.  Given the weight and size of the D50, it may be difficult (impossible?) to attach to a Boom Arm.  Unless you rigged some sort of support, the D50 would be dragging the floor and increasing the downward force and overall drag on the Kapex head.

IMO, using a D36 with your Kapex is good choice while a D50 would be a very bad choice.

Regards,

Dan. 
 
Karl,

It seems to me that the purpose of your post and potential purchase of the larger hose is that you are not satisfied with your Kapex's dust collection.  Don't get me wrong, I would not get rid of Kapex for anything.  I absolutely love this saw.

I initially used my 27mm hose with it and my ct22.  I did not seem to get the great dust collection everyone talked about so I went with the 36mm hose.  While there was an improvement, there is still a lot of additional dust on and around the tool.

I used to have a DeWalt 705 with a dust bag that seemed to do a better job of dust collection than the Kapex.  The difference may be that the Kapex is a slider while the Dewalt was not.  I am not experienced enough to know if that makes a difference.

Neill,

The difference in dust collection between a fixed & a sliding saw is HUGE. This is because a large portion of dust collection for either of these saws begins right at the blade and has little to do with a vacuum.

With a slider, you can effect the 'ejection angle' of the debris depending on where the blade is relative to the stock when you begin your cut.

Shouldn't matter much with the Kapex given the way that the shroud is manufactured. NO saw/CD combination is 'dust free' although in my limited use of the Kapex (with DC) I found the amount of dust not collected to be not really significant. 

This however is in comparison to my 12" Bosch slider. The amount of dust that my saw actually catches is insignificant :(

Harry,

Thanks for the info.  I thought there would be a difference and that's why I brought it up.  Glad you were able to compare slider to slider.

The Kapex is my first real SCMS.  I also have a Makita cordless miter saw that is a slider.  It uses a 7 1/2" blade and is rather light duty.  It is great for what it does.  It only weighs 23 pounds so it is quite portable.  Great for moldings, etc. on-site.

Thanks all for the advice.

My Kapek is permanently mounted in a recess on a line of base cabinets in my garage.  The ct 22 sits underneath.  In essence this gives me a large/long area  for cross cutting.

I was thinking about the shorter 50mm hose because I would just leave one end connected to the saw, disconnect the other end from vac and roll the vac out when I'm sanding or using the domino w/ the 27mm hose.

Brice, I like the idea of the less expensive Rigid or shop vac hose.

Peter, thanks for explaining that the 36mm hose slips over the fitting.  I was unclear on that.

Again, thanks all.  I'll look for the cheaper approach.  If that fails, 36mm it will be.

I have surveyed the hose comments and am confused, largely I admit because I am not yet metric-ized. Want a larger throughput to improve collection off Kapex only. No hand tools involved. Prior comment points out #452897 reducer will convert 36mm to 27mm. Using Non antistatic hose.

Kapex dust port is 36mm I.D., O.D 40mm. as I measure them I currently use the standard tool dust hose which fits INside the Kapex port and other end is 58mm (aka 2" shop vac hose). Please tell me what hose fitting would fit over OUTside of Kapex, and what size connecter and/or hose  is available at vac end. Part numbers would be appreciated.

TIA

As noted above, the tool end of a D36 hose will fit over the Kapex port.  As Forrest describes in this post, you can connect a shortened length of D36 hose to your Kapex, and then use a short length of D50 between the D36 hose and the vacuum.  So, you would want:


You can disassemble the fittings on these hoses, cut to the desired lengths and then reassemble the fittings.

Maybe one of the dealers here can offer the shortened hoses you would need.   [scratch chin]
 
Many thanks to all and the preceding comments discussing reasonable expectations of collection efficiency by virtue of being an SCM.

I need to take a picture after I do some trim work inside a finished house some time.
Allthe dust that is not sucked up by the vac, falls on the saw and right around the saw on my mft.

There is barely any dust that falls on the floor or goes anywhere else in the room.

I make more of a mess drilling a few holes then I do installing a couple rooms of crown.
 
On other FOG threads qualified experts have discussed the differences in dust collection with the CT's and conventional shop DC systems.

In my own shop most of the fixed equipment is designed to connect to the main over-head DC system, using 100mm or larger hoses. This main DC system is low velocity, high volume. Like the classic portable Festools, the Kapex is designed for use with the CT-like vacs, which are high velocity, moderate volume.

Before I had the new shop I bought one of the first Kapex sold in Los Angeles. While waiting for the day Kapex went on sale, I had followed the posts from FOG members, who recommended using the 36mm hose instead of the 27mm which is standard with CT. I already owned a CT22, so with my Kapex I purchased a 36mm x 3.5m AS hose. Compared to every other sliding miter saw, the Kapex with CT22 was outstanding. Of course the Kapex creates far more dust than does a TS55, meaning it can fill standard disposable CT22 bags very fast.

When I did move into my new shop I had provided a 100mm hose to connect a Kapex to the main DC system, using a reducer. Frankly the low velocity of the DC system was less than ideal for the Kapex. My second plan was to buy the Re-usable bag for a CT22 which would be parked under the extension of the Kapex, using the 36mm AS hose. The Kapex plugs directly into a 120v/20a dedicated grounded outlet. The CT22 is plugs into a dedicated and switched 120v/20a outlet. While I still use the Kapex with the CT22, to catch dust missed by the Kapex, I have installed an common radial saw collection hood behind it. The fixed Kapex also sits on a down-draft table. When the re-usable bag starts to fill, it is emptied into the same kind of plastic bag as used my the main DC system, and picked up by the sawdust hauling contractor.

In the field my Kapex on a portable stand is used with another CT22, with disposable bags. That same CT22 is used with my other portable field Festools.
 
I have a CT mini that I use for my router table and small (10") bandsaw.  I use 50mm hose to a dust deputy and then 50mm hose to a 4" adapter.  Without the dust deputy the bags fill too fast for the setup to be usable.  Given the stiffness of the 50mm hose I doubt that it would be practical if you wanted to attach to a hand tool (like a domino).  But with the dust deputy the setup should work fine with any CT series and any fixed tool like the Kapex.

In my shop I have a high performance Dust Extractor with 100mm hose and that works better.
