    Re: What was it?

    Well, chlorine will harm the fish, and the bacteria don't kill algae.

    The balls just let the bacteria grow, and they do help to accellerate the decomposition of dead algae, fish waste, and other...

    Re: What was it?

    I think that was the show with the small, multi-faceted, ping pong ball sized plastic spheres that are used in pond filters as a growing surface for beneficial bacteria.

    They have a lot of little...

    Re: water heater bypassing

    That's exactly what happened with my system. The Pressure regulator for the whole house was malfunctioning, and letting the pressure creep up. The T/P valve on the water heater - set for 120 psi -...

    Re: sparking black and decker cordless drill

    The sparking is pretty much a normal thing. It's most likely coming from the motor's brushes as the commutator in the motor turns.

    Nearly all 'brush-type' or 'universal' motors do this.

    Re: ceiling fan noise

    Yeah, It's old enough to consider replacing it.

    You don't mention the quality level of the old fan, but the cheaper ones do tend to hum. My preference is for Casablanca, but there are any number...

    Re: Use of Power tools in South America?

    Most hand tools, like drills, routers, jigsaws, etc., use universal motors (with brushes in them). They will run on anything from direct current (DC) on up to 60~ or beyond. Their only critical...

    Re: Dead table saw?

    Potentially, yes... But it'd probably just turn VERY slowly - not run up to speed.

    To truly reverse an induction motor requires switching some wires in the motor's interior. Some motors -...

    Re: Dead table saw?

    Okay, it sounds like the start winding in the motor isn't 'kicking in.' Your induction motor has a centrifugal switch in it that works only on startup. Once the motor runs up to a certain RPM, the...

    Re: Glass Into Old Solid Cabinet Doors

    Sure, it can be done, but depending on your original doors, it can be a considerable task. You need to remove the original - wood, I presume - panel. Wood panels generally are free-floating - not...

    Re: Popped Ceilings

    Bad news and more bad news... There's a good chance that your older popcorn ceiling contains asbestos particles. If so, proper removal will be expensive, and quite a hassle. You'll have to get a...

    Re: Dead table saw?

    You mentioned a hum, then a click, in an earlier message. It was probably a reset switch (circuit breaker) popping after the capacitor caused the current to go over its limit. There ought to be a...

    Re: Dead table saw?

    Okay, your saw has an induction motor, and there are no brushes (or commutator). The likely culprit is the start capacitor. It's number 17 in the diagram, P/N STD376110, and the website shows it...

    Re: Dead table saw?

    You'll probably only be able to see the portion of the commutator that's directly under the brushes, but you'll be able to see arcing or burn marks in that area by rotating the motor while looking...

    Re: Dead table saw?

    [QUOTE=johnL;700]

    I'm assuming, from your response, that it is a direct drive saw. If so, then yes, the arcing, burning, and probably deep grooving of the commutator will be evident.

    As for...

    Re: Dead table saw?

    The problem depends on the type of saw it is.

    If it's a 'contractor' saw - with the motor hanging out the back - it's most likely the start capacitor. That's the sort of can-looking thing that's...
  17. Re: Where to find a key switch for an electical circuit?

    You could use a low voltage key switch - like an automotive switch - and a low voltage transformer to power a 20 or 30 amp relay. Run the 120v~ circuit through the relay's contacts. When the key...

    Re: Basement Ceiling what would you do?

    Consider using one of the newer versions of ceiling tiles. Some of the new designs are sculpted and/or embossed to minimize the 'tiled' look, and can really add nicely to the overall decor.
