I purchased the Shelix Cutter head for my DW 735 planner. I had a Dewalt Service Center install it and just picked it up. I believe there were 2 things that should be noted. First, installing the new cutter head voids the warranty. Second, there is not a “stop” on the motor if something gets stuck. If you have to remove the top to get to anything, and I know this may sound silly, UNPLUG it from the outlet! If not, once a jam is removed the cutter head will start again automatically. The new cutter head does not have what appears a hex shape on one end that if a jam occurs an arm comes down and disengages everything and shuts off power to the machine.

That being said, I am looking forward to using it. Everyone at Dewalt was asking questions and said the finish was par excellent. I will let you know.

Once the top is removed from the DW735 a switch is activated that shut power off to the switch. You can’t start the machine with the yellow portion of the top without taking a screw driver or something to engage that switch. Replacing the cutterhead with a shelix does not remove or disable any safeties. That said if you are going to be working on any power tool disconnect all power. My DW 735 has no arm to drop if a jam occurs. If the cutterhead is stopped for any reason when power is on the cutterhead drive belt immediately melts and it’s $40 for a new drive belt. I don’t know if that is a designed safety feature but it is a very effective one. I now have a spare drive belt just in case.

John,

I am sure what you are saying is correct. I am just going by what I was told by the service center. Exactly how / why I don’t know. I’m not much on machinery hence the reason to have it done by professionals that know what they are doing. Me, I’d have parts left over :-)

I did have a short piece (with the original cutter) kick back on me once. Always plan a longer piece!

I put a shelix cutter in my DW735 and the only part that’s not used is the cutter lock which engages when the cutter inner cover is removed. All the lock is for is to hold the cutter in place so you can remove the blades. You push the lock down to rotate the cutter to get to each blade for removal. The safety switch that kills the power is engaged as soon as you take off the very top cover. There is no auto stop when a jam occurs other than you turning off the power.

They could have been referring to a piece getting trapped and causing the cutter to stop and someone trying to remove it without un plugging the unit. You seem to be more experienced with this than me. All I was trying to do mainly was to make sure anyone working on or trying to remove a jammed piece make sure the machine (actually) all machines are unplugged from the power source.

Does the new cutter perform as well as people are saying?

I’m very pleased so far with the shelix head, only had it about a month. It is quieter and so far I’m getting no snipe with it. It took me a long time to suck it up and spend the money but I’m happy I did. Also it was an easy install. The only unnerving part was taking a mallet to drive out the old cutter and drive in the new. I think it took me just about 1-1/2 hours to get it installed. I did get one slice in my thumb handling the shelix cutter while installing it and that was when I was wrapping the plastic around it.

Why me: I wasn’t comfortable installing myself. That is why I sent to a Dewalt Service Center. I figued they knew what they were doing and could do it better and in less time than I could. I hope it performs well. My old cutter head was chipping out some wood in spots. I was going to change or sharpen the knives but decided the Shelix was a better bargain as replacement knives can get expensive over time.

The shelix cutter in my opinion is well worth the money.

Either something is lost in translation or they don’t know what they’re talking about.

I like my setup.

WhyMe has it correct, the cutterhead lock is the only thing that is not used on a Shelix retrofit for the 735. It is still pretty easy to change the cutters with the supplied screwdriver.

I mostly plane figured white oak, and the Shelix has solved my tearout problem. Batch after batch, wood emerges from the planer smooth and flat, with nary a trace of tearout. I have been able to plane boards with irregular grain that would have been impossible with straight knives.

I had to modify my material removal gauge to get it reading accurately. The depth stop also needed adjustment once the new head was installed.

Best of luck with it.

A question: The depth stop on the side that keeps you from taking more off than the thickness you are trying to reach, 1/4 1/2 3/4, does it need to be readjusted?

Here’s the long answer…

Yes, you may need to adjust the rotating depth stop mechanism so that when you set the dial for 3/4” boards you actually get 3/4” boards. That adjustment is actually easy. It is just a bolt with lock nut under the mechanism. It reminds me of a depth stop turret on a plunge router.

The material removal gauge may also need to be adjusted. This is the gauge on the infeed side that indicates how much material will be removed… 1/32”, 1/16” etc. The gauge has slotted holes that may need to be elongated to read accurately. Ultimately you will know if the gauge is accurate by how far you crank the planer down. After a fresh pass through the planer, crank the handle down 180 degrees, and the gauge should read 1/32” on the next pass. If not, elongate the holes to make the gauge read 1/32”.

Basically each full revolution lowers the planer carriage 1/16”.

These adjustments are necessary because the Shelix head is slightly smaller in diameter that the stock Dewalt cutterhead. However, Shelix has also started manufacturing a full sized head for the 735 that doesn’t require these adjustments. The full sized head requires that the carbide cutters be removed prior to installation, whereas on the original Shelix it was optional. Unless you specify that you want the full sized version, Shelix likely shipped the standard undersized version.

It’s really not a big deal, just something to be aware of.
