I can't change the blade on a B & D miter saw.
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? |

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.

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. Nonny "Dave - Parkville, MD" wrote in message ...

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. -- ______________________________ Keep the whole world singing . . . .

I can't change the blade on a B & D miter saw.
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.

In addition to the other good suggestions, slather the nut and shaft with nut-release juice. |

Once it's good and hot, try loosening it again. It should pop off. Not on my watch. A 1500 Watt heat gun, maybe, but not a propane torch. Lew |

Not so. All blades release by turning the nut the way the blade
turns. True for table saws, circular saws, miter saws, pavement saws. -- ______________________________ Keep the whole world singing . . . . DanG (remove the sevens) wrote in message ...

With the saw blade turning toward you to cut, the nut comes off the way the teeth point. Assuming the blade is installed correctly. :-) |

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. |

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 have a Black and Decker Firestorm and to the right, at the very end of the motor housing (the big bulky orange part where your handle and such are), you can insert an Allen wrench or hex key and while it technically does not lock, it provides counter resistance while you are trying to turn the nut at the blade side. |

I don't think I have ever seen so many stupid answers to a question in my life. The saw has left hand threads. Instead of turning it counter clock wise, turn it clockwise to loosen it. Jan the bland into a small scrap of wood.. use a box wrench and hit it with a hammer. A couple of good smacks will loosen it.

Jan the bland? 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. Jan the bland? Auto correct screwed up. Was supposed to say, "Jam the blade into a scrap of wood." LOL, you said exactly the same thing I did except I used the words clockwise and counter clockwise. The blade cuts in the clock 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. Never jam anything into the fan blades of the motor. |
