If one joint failed, the rest may be ready.


Also, the replacement teeth are guaranteed to be differently -
shaped than the worn teeth, making sharpening a much more
time-consuming process than it needs to be.


I suppose size/weight could have some implications here, too. Put a
single different sized tooth on and throw the blade out of dynamic
balance.


I wouldn't be too concerned there.


On my dry saw, I've discovered that I'd been cutting steel using
a blade missing a couple teeth. *Performance was down.
but it still worked without discernible vibration.


Doesn't your dry saw run at a considerably slower RPM?


About 1300 RPM no load vs 3200 RPM for a typical miter saw.

My nit is that they never showed any additional silver solder being
applied. *Is there enough after removing the teeth? *I'd be wary of
that.


He *implies* that he put fresh silver solder in the joint
between shots. *(Must look up silver solder *paste*!)


Powdered silver solder in white flux, just what we need. *


Substitute black flux and you've got a deal!


(What?)


How cool would that be? *Pre-fluxed silver solder paste!
That was before I discovered it costs 50 smackers for
an ounce. *Oh Well!



FIFTY BUCKS AN OUNCE?! *Nevermind.


Fifty bucks an ouch?


Yup!

You'd get a lot more joints out of that ounce of flux and filler than
out of a similar quantity of filler rod and a jar of flux by the time
you clean up the joint. The stuff is really meant for furnace
brazing, though, where you have your parts rolling through on a belt
instead of guy with a torch doing onesies. I've used it for gun work
for putting sights and ramps on, good stuff. Just a mite spendy in
today's metal market.
