i own the ts 55 and ts 75, and they are used, worn but still just like
any tool in the workshop, working well.
wouldnt it be more interesting to see a worn out ts55 take apart and
then analyze the wear patterns instead of speculating on why a part
might (in an uninformed manner) fail or "appears" to be too cheap?
did he take apart a cheaper makita saw (they have a copy of the ts55)?
then do a side by side, but to nit pick at little details doesnt show me
anything.

Does anyone with a TS 55 EQ be willing to tear their saw down?
Would be interested to see that one torn down as a comparison to see what has changed.
In most industries, the first iteration is identifying problems, second iteration is the solving the issues, and third iteration and beyond is cost cutting. I would hope, given the ever rising prices, that Festool skipped the cost cutting part, but the proof is in the pudding.

Your link is blank, but because I've been looking forward to seeing part 2 of his video, I tracked it down. I've been curious about exactly how the oscilloscope image would look for the saw. There are different types of PWM controllers, and I could never be sure which type this was without the scope.
I'm surprised that he didn't notice this himself, but the scope image of an entire rip-cut was very interesting. When you (metaphorically) stand back and look at the real time power fluctuations, that is the cause of the "growling" sound. It's not from cutting off each individual sine wave pulse, but the longer duration feedback oscillation as the controller is trying to stabilize the motor speed from a change.
I see he finally noticed the thermistor on the ends of the red wires. Hmmm, I wonder if he's been reading my comments?

I'm a little disappointed. It appears that the forum Admin has placed the video ID string into an autocorrect entry to delete it from being displayed in any way. This was an educational video, and far better than the previous one.

I too am disappointed in these videos being deleted - there is some very good information and yes some over simplification but by and large I appreciated the opportunity to see detail of the inner workings. Some of the design I like and some not so much - using the vanes of the cooling fan to drive the blade locking pin into is not what I would have thought would have fit in product of this category. The possibility of damaging the vanes or even chipping them and having the debris float around seems high.
The reason we have been given via the moderators was that the owners of this forum had it removed - why they didn't have their employee remove it is curious and perhaps he just wasn't available.
Here is what we were told "I have been asked to remove the video by Festool USA due to possible product liability concerns. This has nothing to do with the discussions here or what has been shown in the video"
So if the product liability concerns have nothing to do with what has been shown in the video why delete the video? Is there some other reason?

Woodn't It Be Neat said:
The video presenter has a reasonable electrical knowledge, and that is the part of this new video that interested me. My original assessment still stands, however. Mechanically he is an idiot. (P.S., even electrically he is a little "iffy". The no-load powerfactor on a motor is supposed to be low. But seeing it go over 90% at load is very good for a universal motor.)
The Fast-Fix arbor lock does not engage the vanes of the cooling fan. It fits into 1 of 2 holes in the disk behind the cooling fan. Because this is upstream from a gear reduction, the force on that pin is very low.
What he is showing is nothing new to me (except the oscilloscope). For reasons I can't go into, I have timed myself on tearing down and reassembling the saw to the same level he shows. I can do it comfortably at 10 minutes. Oh, as [member=48572]Shane Holland[/member] cautioned, don't buy this saw if you see it come on the market. He damaged the magnetic pickup ring on the motor, and that is not a user-replaceable part.

To answer the question why a moderator was asked to do it was simply because an employee wasn't available at the time.

One thing that got my interest in the video was when he criticized the speed selector dial for having only 6 settings, saying it should have at least twelve.
Has anyone out there ever wished that they had more speed choices? Frankly, I can't remember ever taking mine off 6, but I just use it on wood and sheet goods.

That is how I took it
Interesting - when I find out that something has been deleted (like emails from a server) it just makes me want to see it even more. I have been very happy with my TS55, but I did find the video informative and some of the comments are hilarious - wife's with Festool Tramp Stamps. "This saw is something some skinny jeans wearing little prick buys so he can tell all his friends about it while they sit at a "cafe". "

I am glad to hear that, so far I think that is the one thing he has said that has concerned me. If I had stopped to think about it I would have realized he was wrong (he should have as well) because there are not that many blade lock positions available. I am not educated enough about the engineering, electrical or mechanical, to evaluate what he is saying other than to compare it to my use of my TS 75 and personal first-hand experience that it is a pretty remarkable machine. I trimmed about 55' of 1.75" lvl with my ts 75 a few months ago, which is a pretty good stress test in my opinion, the motor was hot but the saw handled it perfectly. I also don't understand why he would not have run some of the tests before he took the saw apart- at least get some baseline readings on power draw and whatever else is possible prior to modification.

The 11 joke is always a good one. I understand why it is the way is is but I wish it was synced to RPM instead.
It would be nice if he would do a Kapex. That way we can maybe see why there are strange failures on them at times that get reported on this group. I am sure I will get some rants about the Kapex comment. [big grin]

I'd love to see a digital display for RPM, temperature, load, etc ... some useful stuff that could tell you how your tool is operating. We've seen the display on the Conturo for stuff, so it's not a big leap for them. Go one further and tie them into IoT .. your tools could schedule their own service when you have an opportune window in your calendar [eek] [big grin]

The Conturo tells you how many metres of edgebanding you can apply with the amount of glue in the machine. Imagine if your tracksaw could tell you how many metres of 3/4" plywood your saw could cut before the blade got dull...

I realize he did not go in with the intention of modifying anything but he ended up doing so anyway. He had to pry some pieces out with screwdrivers. He was open about crushing the brush holder and I think someone else point out that he damaged something else at one point while taking it apart.
I don't think anyone can reassemble a factory made product back quite the same as it came from the factory and therefore I think it makes sense to test whatever can be tested prior to taking it apart. Maybe it had no effect but maybe it did.
