i use a ct-22 and ct-33 with a 36mm for dust extraction with a leigh d4r and leigh fmt and other festool goodies.
does anyone have experience with the 50mm hose and the ct-22/33.
i have had a few small blockages where i had to stop what i was doing and clear the blockage, a minor inconvenience, not a big problem.
i am curious to know if anyone recommends the 50mm hose, or is the airflow restricted because of the larger hose?

 
I find that on occasion the 27mm hose might get some blockages at the nozzle when using the OF2200 and large bits producing large chips. This is caused by the nozzle being inside the OF2200 dust port, rather than going over it like the 36mm hose nozzle. So having 36mm ID all the way from source to extractor helps in these situations. But never that I can recall did the 36mm set get blockages that I felt the need to go ever larger. In fact, larger would reduce air pressure in place of air volume. This is my experience with hand held tools.

For some stationary tools in the workshop (thicknessers and table saws), I use 50mm ID. For the bench top thicknesser I use 50 from tool to vac. For table saws, I add 50mm extensions from the 36mm Y-piece hose set used with the CS50/70 and CMS.

Justin - just check to see if the hose ID is the issue or nozzle blockages.
 
Anthony,

You hook your CT up to a table saw?  Why kinha of table saw? Contractor size?
 
Justin I think the problem you'll run into with the larger 50 mm hose is attaching it to your hand held power tools. It might be more trouble than it's worth.

Dave, I have hooked both my contractor and jobsite table saws to my CT22. I've also used the CT with cyclone on my jointer and planer. While it works well enough to get the job done it's the not right tool for large/stationary tools.
 
With regard to the FMT, the smaller opening in the FMT itself is going to be a limiting factor.  You will only get so much through that hole and it looks like Leigh is trying to create a vortex effect to get more collection through it also.  That said the front side of the unit will have less successful collection than the rear where the chips are being directed more toward the hole.

Perhaps one thing to look at would be to use a shorter length of hose to connect to the Leigh jigs.  A shorter hose should increase flow and decrease any material dropping out from friction in the hose itself.

Best,
Todd
 
I use the 50mm non-static hose connected to a CT22 with a Bosch 4100 table and a Dewalt bench planer.  Works great.  However, I do switch the hose when using hand tools.

 
thanks everybody for the replies, you are correct anthony, the blockage is in the nozzle, not the inside diameter of the hose itself.
i am relieved that i dont have to upgrade to 50mm hose, i am very happy using the 36mm, especially as i got it for half the retail price on fleabay!

todd, i will try using a shorter length, i was thinking the same thing myself, and as i have 7 metres to play with, i can cut it up for the kapex and the leigh jigs.

brice and thinkingdog, i never thought of using 50mm hose for the table saw and thicknesser, i normally use 100mm flexible hose and a 1hp dust extractor for these 2 machines, but it would do the job in an emergency. (inside a clients house)

regards, justin.

Festool ones of course. The Festool PRECISIO CS50 and PRECISIO CS70. NAINA sorry.

I also use a small Protool VCP 170 to collect dust from our Hammer N4400 18" bandsaw. Works quite well.
 
Anthony, sorry to be off-topic here; but what is the value of the "CS" saw systems? They appear completely out of price range for the function or quality of tooling. In the States, a good product is the Bosch 4100 portable saw. A great tool at a reasonable price with all the functions of those particular Festools. Are the Bosch saws not offered abroad?

OT but good question - The CS saws are a site saw, but with features not many other site saws bother with, which makes them better than most site saws, and excellent workshop saws. Obviously being a Festool product, the CS are part of a system, therefore there are many interchangeable components with other Festool products. Plus many add-ons to make it more functional and efficient.

Additionally, they have the following features:

Variable speed.
MMC electronics.
Electronic blade brake.
Plenty of power.
Can operate at ground level or at 900mm when legs folded down.
FastFix blade change (CS50).
Blade change above the table due to easily removable top panel.
Motor air-intake pleated filter (CS70).
Lightweight extruded and cast aluminium.
Very nice Festool blade as standard.
Nice blade tilt and height controls.
Pull-saw function.
Three lockable blade positions (distance from operator).
Excellent dust extraction.
Riving knife that can be quickly locked down when needing to trench work piece.
Side extension table (CS50 table can be used with CMS).
Rear extension table (CS50 table can be used with CMS).
Sliding tables (CS50 table can be used with CMS).
Nice rip fence with micro adjust (CS50 rip fence can be used with CMS, CS70 rip fence can be used with MFT3).
Sufficient precision that many users don't use them as site saws but as workshop saws for fine craftsmanship.
