Cut into a Parf Dog

[Svar]

Anodizing alters the dimensions of aluminium by a fraction.

Yes, that's why you machine the part to allow for anodizing.

The thickness of the anodizing can vary from one batch to another.

Yes, by 0.002 mm, so what?

Anodizing will wear in time as well.

Also true, it will only last 200 years of normal use for this application.

Don't get me wrong, stainless is awesome, but I don't see bench dogs as a heirloom or collectible. They are disposable things. There is no practical justification in this case for high end materials.

I like aluminum because it does the job just fine and when cutting on the table you don't risk damaging a blade. This Qwas dog was just under my guide rail for a few cuts then I set the saw for a 45 degree cut and did not notice it would be in the line of cut. If it was SS there is a pretty good chance I would have damaged the blade. As it was although a little worse for wear the dog is usable and the blade is fine.

Meh, so the blade isn't wobbling, it still cuts fine and the dog only has a nick in it?
I'd call that a result.
Ive hit enough nails with circular saws so I dont stress too much if I lose a tooth in the blade.
It happens, TS saws are about as well guarded as it's possible to get so even if a tooth does let go in the future its unlikely to hit you.

If its slightly off frop perfection its usually worth keeping for the times when you are cutting first fix timber and the cut edge is never seen.

Yup, I think the cut is still fine and the dog only suffered a small nick it.  I actually feel like that nick gives the dog some "character" - like it's been well used...

I was also thinking that the design of a tracksaw does make it seem unlikely that I would be hit by anything.  Although I image that if you were hit and depending on where you got hit, it could be quite serious.

Even if the cut now isn't 100% perfect, I'd say it's still the best cut I've ever gotten before, but I've only used "cheaper" tools in the past - Porter Cable 7 1/4" circular saw, Craftsman 10" miter saw, Craftsman table saw, Makita 18v circular saw, Grizzly jigsaw.

Machine shops often use carbide to cut stainless.
So I am not surprised the blade is ok. (And I would not have been too surprised if the blade ad gotten dull)
If it cuts like it did, then it seems like no real worry.
