That is a 1954 saw, and it looks like a 1hp single phase motor made by Marathon for Delta – unless I’m seeing things. Cheers, -- Brad in FL - In Dog I trust... everything else is questionable |

Thanks Brad, |

You were just the guy I was hoping would reply. Will I see a significant power advantage wiring it for 220? None. Also, how did you determine it’s a 28-350? In 1954, they only offered two band saws – and a 28-350 isn’t one of them :) Perhaps you meant catalog number 28-305? Wood/Metal 14” model on an enclosed cast iron stand (28-307 is the same but on an open flared leg stand). Saw itself is a model 880.

I just assumed it was a 28-350. Mainly from pictures, I was in the hospital during the auction (new baby) plus I’ve had limited time to research this saw anymore (new baby) |

I just assumed it was a 28-350. Mainly from pictures, I was in the hospital during the auction (new baby) plus I’ve had limited time to research this saw anymore (new baby) The 28-350 is a 20” wood cutting bandsaw and was not sold in 1954, although it did appear in the 1955 catalog, so maybe yours was a very, very early model – it looks like this (catalog picture): In 1954, all they offered was the 14” cast iron models, either wood only or wood/metal. Cheers, PS: Regarding the new baby – from experience, if you don’t sell them before they turn 4, you will never get rid of them <grin> -- Brad in FL - In Dog I trust... everything else is questionable |

I agree about selling them before 4. It’s so hard to get rid of something when it’s in its prime. So, what saw did I just buy??? |

Yup, it’s a 20 incher! Serial number places it as 1954 but they didn’t show up in the catalogs until 1955 – so you apparently got one of the first ones out of the factory. Nice score for what you paid! Cheers, -- Brad in FL - In Dog I trust... everything else is questionable |

Whoa! Is that the least efficient motor of all time or what is going on? 115/230 V -- Rick M, http://thewoodknack.blogspot.com/ |

That’s good news, and thank you for the reply. I read a lot of your responses and have learned a fair share. Your knowledge and willingness to share is appreciated. |

Whoa! Is that the least efficient motor of all time or what is going on? LOL – I have a 1/2hp R/I motor that has an FLA of 8A :) Actually 14A is pretty typical. Here is the “Rule of Thumb” from the Engineering Toolbox:

I have never seen a 1hp motor rated at 14+ amps on the badge. It’s one thing to see it on a chart but another to see it on the label. They were probably just being more honest than most. -- Rick M, http://thewoodknack.blogspot.com/ |

Haha, back when this motor was built, efficient meant it would still be working at 64 Years old. The cost of electricity where I’m at is unreal. I have been lucky to acquire a decent collection of old machines. Two pm 66’s from 1985. A pm 60 from 1984. A Delta unisaw from 1955 and this latest find. If I’m wondering where all my time has gone, the electricity bill reminds me. |

Old motors may have been less efficient but I have a pile of motors, most older than me, the amp ratings are all pretty typical for the HP rating. And if you use the HP calculator at brads link it doesn’t jive with the chart. Same website so what’s the difference? -- Rick M, http://thewoodknack.blogspot.com/ |
