CT 36 and Jet 12" JP - will they work together?

[HowardH]

I am getting to pull the trigger on a Jet JJP 12 JP and was planning to connect it to a CT36 with the Festool cyclone.  However, I have discovered the minimum recommended CFM for the Jet is 400 and the Festool is only 136.  Has anyone used this combination and has it worked satisfactorily? I don't want to buy a full sized DC if I can help it but if I have to, I'll do it.  That is, if I can find a spot for it.  Might be time to rearrange my garage.

I can't offer much in suggesting a suitable dust collector that will fit in your shop, but I can say this. In addition to the CFM's that the CT will be inadequate for, you have to remember that jointer/planers throw LOTS of chips out. Even the 50mm hose on a CT will likely clog. I'm sure others will chime in with more experience and technical knowledge, but my thoughts are the CT just won't cut it with a machine like this.

I won't comment on the specific jointer/planer you are talking about, but I can speak from personal experience on dust and chip collection.  I have a Ridgid lunchbox planer and first used a homemade Thien baffle rig on a 55 gallon drum hooked up to a shop vac.  I will say that it worked OK at best, would get clogged up often.  I then ended up getting a proper 240VAC Shopfox cyclone DC and the difference is absolutely no comparison.  The sheer volume of chips produced by even a smallish planer is astonishing.  The cyclone nameplate said it had 1165 CFM of suction, but I think that is overly optimistic.  Still, around 10X that of the Festool.  They simply are not in the same ballpark.  For a planer and open-air dust collection like from a miter saw, you need lots of airflow and I don't believe the Festool is meant for such a task.  I have the CT36 and it is marvelous for SANDING, but I would not think it useful for a planer or jointer.

I have since moved across the country and sold most of my power tools including the dust collector.  But I plan to get another DC soon as I feel it is simply a necessary tool for proper dust and chip collection, at least for my needs.  I personally have grown tired of everything in the shop being covered in sanding dust and am willing to invest in proper dust collection.

I had a feeling you were going to say that...  Geez.  Better start measuring and figuring out where I can move stuff around...

What [member=64379]ChiknNutz[/member] said, you will need a dust collector.

When I didn't have a DC, I tried using the new version of CT26 with a 6" jointer and 50mm hose and it worked very poorly, I had to fight clogs all the time. A paper bag taped to the dust collection opening worked better than CT26.

You need to move large volumes of air to get all of the fine dust collected at the source and a Festool CT simply doesn't provide that for bigger machines. It works great for sanders and routers, but is not sufficient for even a 4" jointer.

Also, please keep in mind that the vast majority of manufacturers (including Festool) give you misleading specs on dust collectors.
Festool rates their CTs without any hose or filter installed at 137 CFM. You'll be lucky to get 50 CFM at the end of a 10' long 50mm hose. I measured at the end of a 32/27 mm hose that comes with CT26 with an empty bag and got less than 30 CFM.

I had a Jet JJP12 combo machine.  It needs a LOT of flow and my CT36 is nowhere near enough.  I had mine connected to a 3hp Oneida cyclone with 4" ducting and chip collection was excellent but I wouldn't even think about a shop vac type extractor for that machine.

I have since down sized now to a DeWalt 734 portable planer and have used my CT36 with a 50mm hose through a dust deputy and it is only partially effective at chip collection, I still have to do a lot of sweeping afterward.
