Hi guys

I have ordered a dewalt 733 thicknesser this week

Any advice on extraction I have a ct33 and a midi not sure if either are suitable have looked into it a bit

I don't really have room for a big stand alone extractor is this going to be a problem ?
Also any pics of a mobile cart type thing with extension tables would be appreciated
(Another workshop project
.I seem to spend more time making things to make things)

Thanks in advance Mick

I have that planer. I don't use it much in the shop . I have a full planer thicknesser  for that. I mostly use it on site
the ct22 fill up too quickly to use that . so I use n old separator. its a pain but worth it
if your in a shop I think you really need a high volume low pressure dc .
its amazing the amount of shavings it generates

The DW735 has three knives and two speeds and also has it's own built-in
chip ejector fan so you can get away without anything external to the planer
except for the bag to collect the chips in. I don't know if the DW734 has this
feature.

I've had my DW735 for over 10 years and use it with my shop dust collection
system but I think the chip ejector fan in the tool helps greatly with pushing
the chips to the dust collector which is30+ feet away as the pipe runs. I never
get any build up of chips on the table or spilling out on to the floor.

I like having the two speeds and the lower profile of the machine compared to
the DW734.

The DW735 has repeatedly been rated one of the better lunchbox planers in
review after review. I don't know what the difference in price is today but I
looked at both DeWalt models back when I bought mine as well as a couple
others and chose the DW735. Only thing I would change (and plan to) is to
install a Shelix cutter head and ditch the straight blades.

Actually I think the current model is the DW734 which has a three knife head
but is the same basic design as the DW733.

I wonder if the 735 cutter head and the 733 head are interchangeable? That
would give 733 owners a way to increase the number of cuts per inch by 50%
(same RPM but one more blade).

I worked with the 734 for years, then over the summer converted to the 735, and have been very happy I did.  The chip ejection feature is indeed impressive.  One time I  forgot to turn on the grizzly DC, and the planer still managed to shoot all the chips through the 25 ft. flexible hose into the SDD without clogging!

I don't think the heads are interchangeable b/w the 733 and the 735, since the 733 only has a 12" capacity, whereas the 735 is 13".  There is now a Shelix head for the 733 however: https://shelixheads.com/SHELIX_for_dewalt_12_inch_Planer_(DW-733)

Installing a Shelix will help with the occasional clogging you might experience due to the lack of a strong ejector fan on the 733 (I used to get clogging from time to time when I was just working with a shop vac on my 734).  The series of individual cutters on the Shelix produces tiny chips as compared to the long braided strands you get from the single knives of the stock cutterhead. 

The Shelix is expensive -- more than what you paid for the planer in fact -- but it turned my 735 into a completely different machine.  The planer is an incredibly loud tool, and that noise only gets worse as the knives dull -- and they can dull quite rapidly depending upon the material you're working with.  I found I could still get a lot of mileage out of my dull knives on the 734, but I had to add an extra step of sanding down all the plane tracks.  The Shelix brings down the noise level to that of your other power tools.  And the finish they give to the wood is superb, requiring at most a finish sand after assembly of whatever you happen to be building.  And if you ever get a nick in one of the knives, you can just replace that individual cutter, as opposed to having to install an entirely new blade.  The cutters also last a lot longer, and can be rotated 3 more times, prolonging their lifespan by orders of magnitude over the standard cutterhead.

An intermediate solution that was mentioned above would be to swap out the stock knives for carbide ones.

FWIW...I just noticed that Holbren is now selling the Byrd Shelix for only $375 including shipping.

Not bad.  I paid 398 plus tax (free shipping) for mine.

Thanks for the heads up Cheese. I ordered the Shelix for my DW735 should see it in a few days. Might be a while before I get to install as I am busy at work for the next month or so and also I wouldn't want to make a change such as this in a tooling setup in the middle of a project.

I ordered mine from Holbren and it should hit my front door today.   

@Bob D. I found this video to be pretty helpful for doing the install.  He's one of the few to get the odd metric sizing on the shaft nut correct:
