delta bandsaw blues
I need a little advice.
The open stand Delta 14" bandsaw that belonged to my father has a bad motor on it. Not sure what happened in storage but it overheats in a hurry. It sounds horrible too. Run it for about 30 seconds and you can smell the motor insulation cooking. In that short period of time the motor case get uncomfortably warm too. This occurs with the belt off and yes it spins freely. The motor nameplate says: "HP - 1/2B" (????) Since this is a 1/2 horse motor maybe it is time to upgrade to a 1 horse. I see some Delta band saws come with 1.5 hp motors. Should I go all out and get a 1.5 hp motor or is that overkill? I need new tires for the saw. Are the Delta tires the ones to get? My father put a household light switch on the saw which really looks hokey. Any recommendations for an suitable on-off switch? Should I order a new one from Delta or is there something else that I can get that is better. I see that there is a release lever version of that same 14" saw. Should I get the parts to upgrade the beast? That spring loaded tensioner is a bear to adjust everytime I go to change a blade. |

A household light switch does not have a very high amp rating IIRC. That could be causing the over heating. |

Delta is quite proud of their motors so I am going to go hunting for a cheaper alternative. Any recommendations? Baldor? GE? Maybe I should just throw a 1/2 hp motor at it, sell it and get the enclosed base version and be done with it.

My Rockwell 14" BS has a 1/2HP motor and it resaws 6" hardwoods
without problems. Haven't resawn with a larger motor so can't compare. I bought tires from Suffolk Machinery were my blades come from. Presoaked in hot water 15 minutes then stretched them on the wheels. On Mon, 12 Jun 2006 06:53:41 GMT, "R. Pierce Butler" wrote: I need a little advice.

By the time I get done adding the good stuff to it, I probably could have just bought the better saw. You HAVE a better saw. Not going to find its equal in the current crop of 14's. Although there are a host of things that could be wrong in the way of motor/pulley/belt alignment that could do what you've described, it's also easily possible that a motor stored for a long time could have had the shellac spring from its windings. You know it's a NEMA 56, but you also want to consider something else when motor shopping. I got a 1 horse Baldor for mine, and the capacitor/switch box was on the wrong side of the motor casing, preventing me from opening the lower door fully. Had to swap ends on the motor. Your choice as to motor quantity. 1.5 is at the upper limit, or perhaps past it for single V-belt operation, and then there's the slip in the band and tires. Wouldn't spend a lot of extra to go over 1HP. Tires from the same source as the motor, most are the same item, based on description. Link belt is a real nice option, since you'll need a new belt anyway. Detensioner is something like that extra half horsepower. Don't need it if you work the saw a lot, can manually detension if using it irregularly. You can spend all kinds of money chasing perfection in guides, blades and dust collection too. Use the saw and find out which you need and which you can do without. Oh yes, motor-rated contacts are put into standard-looking wall switch packages. They're six-eight bucks versus 89 cents, but you just need something to make/break, so unless you're offended by the aesthetics, a switch is a switch. |

Should I order a new one from Delta or is there something else that I can get that is better. Toggle switches were used for years. Held up well. Low cost. Doesn't have that big off button that you can slap from afar if you get in a bind, but functional. I see that there is a release lever version of that same 14" saw. Should I get the parts to upgrade the beast? That spring loaded tensioner is a bear to adjust everytime I go to change a blade. Requires some fairly close tolereance machining on the overarm casting to retrofit the quick release/preset blade tensioning system. You can get the better spring, and a crank handle to make tensioning an easier task. Be sure you get the right RPM motor, particularly if you go to the 1.5. When Delta changed to the 1.5 hp motor there were corresponding pulley and guard changes because the output rpm changed. So if you buy a 1.5 that would be for a recent model Delta, it would not work without those changes. No matter the hp you want a 1725 output rpm. Frank |

Anyone have any comments on WEG motors? Delta switched from Marathon to WEG motors on the "domestic" units. That is what comes on a Unisaw these days. While it is my opinion that they are not as good as Marathon or Baldor, they test fairly well. Frank |

It could be just a stuck centrifugal start switch. If it stays in start mode
it'll both make a weird noise and overheat quickly. It doesn't take much surface rust on the shaft or gummed up grease to keep the switch from moving. It's inside one end of the motor, so you have to open the case, but it's a simple fix to free it up and get it working correctly again. Then, if you haven't over cooked the winding you will have a good motor again. A bad start capacitor can cause similar problems. They can go bad in storage. If it has one, take it to the motor shop and buy a replacement. They usually cost $3-8, so it's worth the gamble. -- Charley "Peter Huebner" wrote in message t... In article , says...

You can take it to the rewinders and have them check it out for a small fee, usually. Not worth rewinding a small-ish motor I was told a couple of months back, due to the price of copper[wire]. Unlike Leon I don't believe your switch has anything at all to do with it. A scorched switch would not make your motor overheat rapidly like that. Rewinders often also sell 2nd hand motors that are in good nick; I got one for the lathe while I was there. -P. -- ========================================= firstname dot lastname at gmail fullstop com |

I will take it apart and check anyway. There is no cap that I can see. |
