Check twice, then check again

[Earl of wood]

I was breaking down some plywood with my TS55.  The first cut I did using pencil marks. Made a good clean cut. Then I decided to use my new Parf Dogs to make a square cut. Set it up, checked it and started to saw. Near the end of the cut I felt a little resistance but I thought the motor housing was hitting the tall Parf Dog holding the rail. When I was done this is what I found.

The setup

OH my

The result

I had cut thru the stainless steel Parf Dog.  I checked the blade and found no chips or broken teeth. Festool is good.

So now I will check twice then check again.

Ouch!  I would actually avoid using the 4th small dog in this scenario.  Your taller parf dog on the front corner of that table is performing double duty.  It aligns the track and the work piece at the same time since it has both the wider profile matching the short dog and the skinnier profile of the taller dog.  I think that's the beauty of these.  And they keep your dogs out of harms way.

That sucks, I'll have to keep this in mind when I go to use the dogs I just got.

However it appears to be a nice clean cut.

And members worry about cutting aluminum with the Festool blades. Tells you how good the blades are.

Sorry to derail this, but do you happen to have a thread made on this MFT table? I assume you rolled your own, I'm undertaking a project like this and really like how you have it setup.

How did the blade not chip  [eek] [eek] [eek]

What blade was it?

 

[sancho57]

you could make a kewl I phone stand out of it

 

[gnlman]

Yeesh.....things could have always been worse.....thanks for posting this, good reminder...
On the postive side, I see almost no chipout on the dog.....lolol

Be glad it's only a Parf dog. I did this with a palisander dining chair.  [embarassed]

You're right about the blades, be it that it's even stainless steel and not aluminium.

That is exactly what I meant.

[wow]

wow. I'd contact the manufacturer of the parf dogs and see if they'd trade you for a new one so they could have that one for their 'museum'. If I was the manufacturer I certainly would!

 

[rmwarren]

Ouch! that is one tough blade.

Avoiding that situation was the prime reason for the clips that go with the rip dogs, they offset the guide rail so the kerf just misses the MFT hole/dog, as well as locking the rail to the tall dogs.

I did learn the hard way that when cutting with the TS tilted at 45 degrees the situation was a bit different... at least the dogs are only aluminum.

astonishing that the blade did not blow apart! i'm no blade expert but i would be inclined to have it inspected, while being re sharpened(!) by a sharpening service who can closely examine it, to avoid any future dangerous failure. Just a thought...

I used plans by Timtool called MFTC.  There are several threads on construction.

No, don't do that.  Keep using it as a reminder.

Sure, Peter Parfitt (FOG member) will be thrilled to hear that one of his dogs got riped to shreds.  [tongue]

As demonstrated, the truth is that good quality blades can take this easily on occasion. Only harm done will be some extra wear on the teeth.

I use lots of reclaimed lumber and have hit the occasional small, embedded steel nail when sizing material with my TS55.  It never looks like it hurt the blade and the blade still cuts solid wood just fine, but when you go to melamine or plywood, the cuts get a little raggedy.  I bought a new blade and that fixed raggedy cuts.  I'm saving the old blade for cuts on old lumber.
