Domino 500 at burn level temps

[Rick Christopherson]

Well that was entertaining.

I didn't make the posting without doing some checking first. Just stick a direct-read thermometer into the exhaust port of the CT vac and you'll see that it won't be up at the 130 degree range.

Care to wager?  Put your money where your mouth is.  Remember, ambient temp was about 95 degrees that day.  Also, care to address the body temperature fact?  Body temps vary, but since we all know that std. body temp is 98.6 degrees, I'm wondering where in the world you're coming up with your calculations.  Plus, did you consider, perhaps, that if the Domino is emitting 140 degree air (or thereabouts), the vac will be sucking in 140 degree air, thus increasing the exhausted air?

I mean, these things aren't difficult.

This is nearly as good as watching paint dry [popcorn] [popcorn] [popcorn]

You may or may not have a problem . You done the right thing rang Festool and exchanged the machine.

Dont think its a reason to declare the end of humanity .

Lets not try to blow single issues into disasters. Lets get a grip folks

Hope the new one is more to your liking, but please let it run in first .

I am glad Festool has resolved your immediate issue . [smile]

My proposal that self-interested people ought to be prohibited from making false statements that benefit them

What? How would Rick saying that your FLIR is not calibrated (right or wrong) benefit him in any way..?

Because I'm saying the Domino (at least mine) was of poor quality and/or dangerous to the end user.  And if fewer people Dominos because they are either poorly made or dangerous (or if Festool is forced to recall them because they exceed allowable standards), then Mr. Christopherson sells fewer of his gadgets.  Pretty simple.

There are a few Festool's that I don't believe make the grade and that is well documented, the D500 isn't one of them. Some Festool's do run hot, my RO90 and my D500 are almost uncomfortable to the touch after extended periods, but nothing I would consider painful or dangerous.

Maybe you got a bad one, or maybe your FLIR is inaccurate and the false data is amplifying your perception of just how hot it is. Those iPhone version are indicative and for relative comparison, not an absolute measure of temperature. You've only got to see how expensive their serious pro ones are to realise the iPhone versions are more of a toy/cool gadget.

Please just that darn tool back if you are under the thirty day window and forget about the value of your time.

It's easy to fact check assumptions via Google.

Internal body temperature is typically 98.6* F but skin temperature is less.

Different parts of the body are at different temps but ambient temperature does have a significant effect.

At ~95* F hands are typically just under 97* according to this chart.

If the Domino is unsatisfactory return it.

But if one is moving around, then the body temp goes up (go take a jog, or sit in a sauna for a test).  Basic physical biology, man.  But stay tuned... Part 2 of the video is on the way (and, though I can't blame you for not tracking through all of the posts, but arrangements for the domino to be returned have been made).  Highland Woodworking is awesome.

I own an iPhone FLIR and it's pretty cool and handy, however if I had to place my life on the line because of its accuracy, I'd go grab my Fluke gear instead. The FLIRs are cute, clever and convenient but there's a reason FLIR still promotes and sells their $6000 IR cameras.

The whole thing with IR detection, is detection of emmisivity, if the emmisivity levels are incorrect, the temps could be off by 20-30 degrees.

Let's please stick with technical facts. I'm extremely apprehensive to even post this, and at the first sign of conflict I am going to come back and remove my participation from the thread.

There was an issue I had noticed from the beginning, but I withheld comment until such time that the discussion became less heated. I hope that time has now come.

In the original and subsequent videos, I had noticed the outline of the plastic body of the motor housing (A) in the composite visible/IR images. (The FLIR system composites both visible video and IR video to make the final output video.)

To confirm this, I replicated the viewing angle of the Domino machine utilizing key features (A&B) to ensure I was accurately representing what the non-IR version of the camera was seeing. Then I replicated the location of the IR crosshair (C).

As you can see, the crosshair is actually pointed over the top of the plastic motor housing. This location is not of any mechanical component. It is actually the main exhaust port of the motor's cooling fan. You can confirm this on your own Domino machine by (carefully) placing your finger forward of this plastic housing and feeling the air flow exiting the motor housing.

Having an elevated air temperature at this location is not abnormal. It actually means that the motor's cooling fan is doing what it is designed to do.

In the event that the original poster has an elevated motor temperature, it is a sign that he has a problematic motor, and worthy of a warranty replacement. It does not, however, point to a design flaw with the machine.

Edited for grammar and prose.

P.S. Thank you Seth.

This is a duplicate post. I just wanted it to appear on the second page of the topic as well as the first page.

P.S. In all fairness, I am seeing that the FLIR-One camera is not properly aligning the visible and IR video components. Regardless what that may imply as to the quality of the FLIR system, it doesn't change the conclusion that the original IR portion was detecting the output of the motor cooling exhaust, and not a mechanical component.

A masterclass in deduction and reasoning!

To take the flipside of the same outcome / I'm an ordinary user of a Domino 500, sometimes I'm probably a little slow with it, linger before or between cuts. But it's never unbearably hot in any of the locations I'm likely to touch.

Perhaps it's an erroneous sample of one, perhaps my CT26 pulls more air than anyone else's or maybe there just isn't a problem and it's one of the most unique and beautifully revolutionary portable woodworking machines ever made?

In any event I'm not giving mine back

I'm not going to go over the above, because I do not want there to be any suggestion of "conflict."  I will note, however, that the entire explanation above (valid or invalid, no matter) is a 100% different line of reasoning than the previously-alleged failure to calibrate the FLIR.

At this point, I don't care, though.  I have a new Domino.  And, I think I've made my point that Festool tool quality and/or design (coming from someone who has probably close to $15,000 invested) is subpar.  When one has to order two of [Insert Tool Here] in order to get one good one (as I have with four MFTs, Two TS55 Req Track Saws, and Two Dominos), it is prima facie evidence of either a poorly-run company, poorly designed, or poorly-manufactured tools.

The fact that apparently dozens and dozens (or more?) of folks are having their Kapex's fail (mine has not . . . yet) is further evidence. 

You might say that I drank the Kool-Aid, but these experiences have been my "wake-up" call to get me into AA.  Sobriety is a good thing. 

 

[Holmz]

Well the tale of "not able to hold it my hand", seems independent of FLIR calibration.

Pretty much every Kapex that smokes has 10+ people claiming that theirs is great and defending the brand.
However the pitchforks do not result in the failed tools coming to life.
It is with a religious fervour that people defend facts.

Basically the domino is a great tool conceptually and on average. But any individual tool can be a POS, and then in its case it is useless.

I'm glad you're sober.  Good luck with your new 500.  I love my 700XL.
