Black & Decker miter sale model 7715 type 3.
I bought this saw at a garage sale. the seller cut a board, said it
needs a blade. But, I can't remove the old blade. The armature of the
motor turns when I try to turn the blade nut. If I "jam" the blade so
it can't turn, the armature still turns. How do I lock the motor to
remove the blade?

Not on my watch.
A 1500 Watt heat gun, maybe, but not a propane torch.

I don't think I have ever seen so many stupid answers to a question in my l=

Not so. All blades release by turning the nut the way the blade
turns. True for table saws, circular saws, miter saws, pavement
saws.

Hello Tom,
My Craftsman hand saw started doing this same thing last year. I think
a brake went bad!? But I am able to change blades. I have a "nut" on
the rear of the blade that I have to hold while turning the front arbor
screw. This keeps the shaft from turning. I hope this is helpful.

If there is enough space between the nut and the end of the shaft
drill a small hole through the shaft end so you can get a awl or other
rod in place to hold the shaft still while loosing the nut.

I don't know if you have the manual or not, but it says to push the
blade into the table top to keep it from turning. Doesn't sound like
that will help you much if the arbor is still turning.

Jan the bland? Auto correct screwed up. Was supposed to say, "Jam the blad=

I used the words clockwise and counter clockwise. The blade cuts in the clo=
ck wise direction, the bolt loosens in the clockwise direction. I have the =
same exact saw. Left hand thread. Tapping the wrench with a hammer is just =
about the same as an impact hammer but with less damage. =20
Never jam anything into the fan blades of the motor.

Are you *absolutely* sure you're turning the arbor nut in the right
direction to loosen it?

FWIW not all saw fixing nuts or bolts loosen clockwise.
The fixing nut or bolt loosens in the direction that the blade spins
when cutting.
Refrain from using a hammer.

Always always with out exception you loosen a nut by turning it in the same
dirrection that it spins when running.
Have you checked for an armature lock button?
Tom, make sure you are turning it the proper way. All saw blades,
no matter what piece of equipment, need to have the nut the same
direction as the saw blade turns to remove. I assume your motor
is on the right, blade on the left and that it turns clockwise
when running. Turn the nut clockwise to remove.
As others have said, I'm fairly sure the saw has an armature lock
(the one that shows up on Amazon does). If you can't find one,
use a scrap piece of wood set just like you planned to cut it.
Cram the blade into the board. Turn the nut clockwise. If the
armature turns and the blade does not, there is a different
problem - the threads are hurt or the nut is rusted on.

In addition to the other good suggestions, slather the nut and shaft with
nut-release juice.
I'm not familiar with this particular saw, but many have a little
"button" near the point where the shaft protrudes from the housing
that fits into a keyway or kerf in the shaft. If there is none,
I'd consider jambing the blade as suggested, then using an air
impact wrench to loosen the bolt holding the blade to the shaft.
Also, be sure to look and see that the bolt is designed to turn
the way you're turning it. For a shaft protruding out the right
side of the motor, it's normally a ccw operation looking toward
the motor from the bolt. For a shaft on the other side, like on a
RAS or many chop saws, the bolt is typically the opposite thread,
as I recall.

Did they have auto-correct in a newsreader back in 2009?
I certainly hope he got his blade off by now.
Black and Decker? I thought they just made disposables. If the blade
is dull throw outthe saw and buy one with a fresh blade. ;^)
Actually, if it is slipping when you hold the balde then it isn't so
tight it shouldn't be able to break it loose. If there is no obvious
brake, which I assume there isn't I can think of two options.
1. See if there is any cooling opening in the moter wherby you can
gently JAM in a screwdriver or other implement to hold the motor while
you work the nut.
2. If you have a hammer\impact drill and can set it up with a socket,
that will surely breal it loose, as long as it is spinning the right
direction. Nothing works better than vibration. Along that same line,
holdingthe blade and doing some light tapping on an open end or box
wrench can have the same effect.
Also might try some wd40 or other penetrating rust\sieze killer but of
it gets between the blade and washer it will more easily slip so be
careful.

Try an impact driver--one of them spring-loaded, hit 'em w/ a hammer
thingies.
Sounds like perhaps original owner may have used it w/o having fully
tightened blade and the starting torque can really overtighten and
slightly stretch bolts. (DAMHIKT :( but I'll tell the story
anyway--got interrupted while changing blade on Dad's little contractor
saw while building the kitchen cabinets. Forgot where was when got back
and just automatically turned it on to go. Spun that sucker on so tight
was a _major_ pita when did need to change next time)
My DeWalt has an armature locking pin; don't know B&D well enough but
look carefully, it's a pretty small little rod that could be overlooked.
If have a buddy or know some service shop well, maybe could drop by and
borrow an impact wrench or get them to do it for you, maybe???

You'd think he'd be suspicious when after asking the guy how long he had
the saw, the guy help up three fingers and said, "four years."

If it doesn't come off any other way find a service station and tip a
mechanic to take it off with a big impact wrench. There should be enough
friction for the impact to trigger even if the blade is slipping on the
shaft.

With the saw blade turning toward you to cut, the nut comes off the
way the teeth point.
Vacuum and then blow all the sawdust out of the saw. Now get your
littlel propane torch out and put it right on the nut while spinning
the blade with your hand. Once it's good and hot, try loosening it
again. It should pop off.
If not, remove any side panel to get a straight shot at the arbor nut
with an impact gun set to tighten. Arbors are reverse threaded.
Did someone try to pull a "saw stop" thing with this one? "OK, turn
it on and I'll swing/jam a bat into the teeth at full speed. That
oughta stop 'er, JimmyBob!"

The easiest way to determine is that an arbor nut turns to tighten in
the same direction as the way the blade turns to cut wood.

Somehow I was thinking "table saw", not miter. If your miter has
plastic safety shields and other plastic bits, no to both.
Otherwise, I like the propane torch because it puts the heat -exactly-
where I point it rather than heating everything to that temp.
YMMV.
