I'm guessing there will be some here who own and use the `nobex' mitre
I've owned one for several yrs, but don't use it all that often. When
I do though, it will likely be a fair bit of work. A fair bit as in
hobby usage .. not commercial.
But even after quite a few cuts with it, numbering by now well into
the hundreds, I've never found a way to use it smoothly.
Mine came with a variety of sizes of those new style flame hardened
blades that show the heat treating coloration and have very sharp and
long lasting teeth.
However those same teeth are absolutely terrible about hanging up.
Even in soft pine.
Even with serious concentration I'm able to only get a few strokes
before the blade will catch. By `catch' I mean just a momentary bite
or snag that throws off the smooth stroke. Easy enough to ram it on
through but not so easy to get a smooth stoke going with the constant
I almost never have this trouble with my frame saws or just plain old
long blade carpenter saws... even a 5 tooth rip I use (usually for
fast crosscutting) is many times smoother to stoke evenly.
If I use the mitre box extensively it really gets to be an
I'm guessing its that style of blade. The teeth are really small and
apparently not intended to be sharpened by the user. They appear to
have very little set, which I suspect is the cause of the problem.
Or am I just a seriously inept oaf, and no one else has any trouble
with those blades?
Looking online for replacement blades, all I see are similar to the
ones I already have. The new style flame hardened ones with tiny
The least number of teeth I see is 12, whereas I can cut smoothly with
a frame saw with 7 teeth per inch... and maintain its set and
sharpness myself. Not much set but is enough to virtually eliminate
But not so good for repeated angles.
I could probably adapt the frame saws' blades to work on the nobex but
it would take a fair bit of tinkering. You'd end up burning up a few
drill bits unless you softened the blade locally. And the nobex frame
has little nubs you'd have to either file off or drill even more holes
in the blade to accommodate.
I wondered if there is a source that has the old style blades that one
can hand sharpen and set to taste but that are designed for the nobex,
or will work on it with only minor tinkering.
