Dim a Sawzall
I am going to cannibalize a Sawzall to crack pecans. I need to slow it
down. If I use a dimmer, will that be adequate, and work? Or do I need to go with a larger rheostat? Steve |

I think a lot depends on how the existing speed control works on the Sawzall and how it reacts to a chopped sine wave like you'd get from a triac based light dimmer and how it reacts to reduced voltage like you'd get with a rheostat. |

Wait a minute he *what if the sawzall is powered by 18 volt battery? * OP never said what powered his saw.- Hide quoted text - - Show quoted text - Since he said the choices were a dimmer or a rheostat, I assume we're talking AC, because dimmer to me implies a typical dimmer for incandescent lights. Also, it would be considerably more involved to get either into a cordless. |

Steve A dedicated speed control will work better than a lamp dimmer because of the inductive component of the universal motor in a sawzall. A rheostat will be your least effective solution - a big Variac would work better - but remember, you will reduce the power of the motor by a whole lot more than you reduce the speed. What youreally want is a variable speed sawzall. |

If it doesn't work, look for a "router speed control" or similar that is specifically designed to work with the series-wound motors used in most hand-held power tools. -- When the game is over, the pawn and the king are returned to the same box.

My first thought would be to use a variac, but those aren't cheap. However they are handy to have around if you're the type of guy who likes to mess with stuff and/or plays with vintage electronics. nate -- replace "roosters" with "cox" to reply. http://members.cox.net/njnagel |

It says that somewhere, but not necessarily in that page. They do say 250 volts dc. ? I'm not sure, but a rectifier should reduce speed, but I would never try something without testing with variac or other series load control. Greg |

Forget about a rheostat because you'd need one rated for at least 1,000 watts, maybe 1,800W. Most light dimmers are also limited to about 600W, an exception being....the dimmer built into your Sawzall. Consider cannibalizing it by replacing its potentiometer (variable resistor) attached to the trigger with regular rotary potentiometer of the same ohms rating, taper (linear or logarithmic), and power rating at least as high (most chassis mount pots are just 1/2W - 1W, while wirewound ones are 5W). However any external potentiometer will have to be electrically isolated because it will be attached directly to a 120VAC source. You'll have to attaching it to something like plastic or wood and make sure its metal shaft can't be touched (plastic knob with NO set screw sticking out -- the set screw should be sunk deep in its hole and the top of the hole covered with plastic). Another possibility is control through something optically isolated. Here's something that explains it: http://www.fairchildsemi.com/an/AN/AN-3006.pdf |

When I look at the $15,000 models, my mind starts thinking, and I'm sure I could cobble together one for a few hundred bucks that would work just fine. And, there's nothing wrong with cracking pecans with your hands. It's just tiring with thousands of pounds of them. I remembered that there is a SawZall with a variable speed (IIRC, and it wasn't a dream), and that could be altered to work. I just need about 1/8"+ of contact with the ends of the nuts to crack them. Shelling and cleaning them will be the fun part to the project. That, and figuring out how to make them fall into a straight line, but I already got that solved. Steve Steve |

I bought this on eBay and initial response it doesn't work for my harbor freight sawzal, so I have to do more testing and verify that it works as stated. I will definitely let you know what I find out.
