Yes...the stock Dewalt just screams at you. Hard to describe but it’s just a nasty, edgy, sound.

It’s very loud while also emanating a high pitched nasty scream...the Shelix is a welcome change.

As an aside, I’ve never worn hearing protection when shooting guns or operating machine tools. That’s probably the reason I’m half deaf.  [eek]  Well, that was just part of living life 50-60 years ago. So consequently, nothing has really been a motivating force for me to use hearing protection because I’m just used to loud equipment (think fuel dragsters) until I purchased the DW 735. That forced me to purchase muffs because it was actually painful to listen to.

So bottom line is...purchase the Shelix for better machine performance and purchase the Shelix for reduced machine noise.

Wow! That's a compelling argument, I haven't running any wood through it yet (no dust collection yet) but I did switch it on – and right back off. It's an awful noise, hate it even with a pair of earmuffs on. Nothing at all like the sound of a big old Powermatic, really wish I had the space for one of those.

Thanks for sharing your experience and insights.

Ya it’s a noise that even permeates ear muffs. Hard to describe but very easy to hate. [smile]
Maybe it’s the harmonics that are generated by it that are annoying?  Think Powermatic, lots of steel & cast iron vs Dewalt and lots of plastic & sheet metal. Just glad I’ve put that annoyance behind me.  [big grin]

I’m actually looking forward to thicknessing some 10” wide walnut tomorrow with the Shelix.

A significant contributor to the DW735 noise signature is the integrated blower for chip exhaust, it howls like a shop vac.  So even when running at idle where there is no noise from cutting action it is fairly loud.  I have confirmed the noise reduction when I did the switch on my DeWalt...it averaged 12 dBA quieter while taking a 1/64" (0.4mm) cut from a 12" wide maple board.

The blower noise makes sense, never thought of that signature.  [smile]

Ya, I did the same measurement with an inexpensive dB app I have on my phone. There was an approximate 9-10 dB reduction in noise level after the Shelix conversion while planing lumber.  [big grin]

I have my DW735 hooked up to a 5hp Clear Vue cyclone dust collection system, and that seems to make the internal blower redundant. So is it possible to disconnect the blower, or is it integral with the motor or planer shaft? Or is it still necessary?

Thanks, Dick

I just run my 735 into a Jet Vortex WITHOUT turning the Jet on. The Dewalt will inflate the Jet bag and deposits the chips inside. Try it once.  [smile]

Wear good quality hearing protection. Really!!! It makes a big difference and it is a BIG deal.

You will appreciate it later in life. The tinnitus is real.

I think the blower drive may be a cogged belt that can be removed without affecting other planer functions...not positive but that's what I recall when I did the head swap.

Thanks Kevin, I'll have to try that.

The blower is mounted to the motor shaft.  One side of the fan cools the motor, the other side blows the chips.  Some guys simply remove the fan all together and see a sizable noise reduction.   I wouldn't do that though because it offers an access point for chips into the motor if you ever forget to turn on the dust collector. 

Instead what I did was purchase a replacement fan and had a machinist friend remove the blower side fins.  The motor is protected and cooled but the blower no longer functions.  You absolutely have to use dust collection though because it will clog without it.

I ended up selling my DW735 shortly after I had the fan made.  I used it on the machine maybe 2 weeks before I purchased a 1960's Powermatic 100 12" and sold the Dewalt.

If someone is interested in the fan I'll sell it for what I paid.  I take no responsibility for whatever happens to your machine by installing it though.  It is for sure a warranty voider.  That said, it worked very well for me.    $20+shipping (~$3-5). PM Me if you're interested.

I have always believed that the reason my cyclone did such an efficient job of dust/chip collection with the 735 is the blower. I used the same cyclone with a Delta table top planer before I owned the 735 and the collection was not as good. Because of this, I don't believe the blower is redundant. Plus, why mess with a good thing. Just wear hearing protection. That's a great idea regardless of whether it would reduce the sound level or not.

A few reasons:

  • For the cat and dog - they like to hang out in the shop with me and I like their company. For some reason they don't leave when I turn the machines on. Don't ever try to put earmuffs on a cat. Trust me on that one.
  • For the neighbors, I hate their leaf blowers, don't imagine they will be to fond of my planer.
  • For me, even with earmuffs the noise is unpleasant.
