Just covered, but appreciate you double checking as well.

You guys know the blades well. (Chris & Mike) They are crazy big and steeply pitched.

The photos reminded me of how much time it took to clean and polish them!:P

They have a nice look to them also. Perhaps Chris may know what they cost. I thought he had unearthed some info on them.:wondering:

I'll see if I can find that old literature. I had taken some screenshots.

Thanks Guys for looking, appreciate it.:D

To save you possible time Chris, I mentioned the (2) page magazine review did not have its price, but did have the Homarts. Having seen both, I could easily see the Viking commanding a little higher price.

Sorry I do not have a video handy, but Chris Hovey uploaded a good one, very well done at: https://www.youtube.com/watch?v=3w_D0K8WeBg&feature=g-crec-u (His other videos are interesting too, you may want to check them out while there.) (There is more than one on Vikings.)

I'm not sure of the actual blade speeds on Low and High, but the motor tag shows 1150 RPM and 1750 RPM. I have never measured them or read them anywhere, but someone may know and post later.

it's basically the same motor as what is in the Sears Homart but without the Craftsman nameplate.

Hi Chris! I never had a Homart motor apart and do believe you. I had posted the motor tag in reference to a speed question from Lawrence and just for general archival information. Any measurements or ideas on the blades speed?

Measure the diameter of the pulleys and I can tell you.

That actually went through my mind as I wrote, but was hoping someone else already had the info so I didn't have to unwrap it.:P

Stephen, here are a couple of speed scenarios. I still have the first generation Viking that I could measure, and will soon, but if I remember correctly, the driven pulley is around 5 inches in diameter and the motor pulley is probably around 1.75" in diameter. On high speed that would be 612.5 RPM for the fan shaft and 1750 for the motor shaft. On low speed it would be 402.5 RPM for the fan shaft and 1150 for the motor shaft.

Thanks Chris for the follow through. Without measuring, I'd say your diameter estimates used for speed calculations are close. The resulting speeds given, probably also close. It will be interesting to see actual measurements at some point or OEM's specs.

There sure is not much information available for these fans. When I bought it, I pressed and then followed up a time or two on the original receipt and user manual, but they were unable to locate either. The original teaser was they "thought" they had them. For a time, I allowed myself to get a little hopeful and excited.

Thanks again (Mike too) for the introduction and inspiration for this Viking!:D

I've got both the early single speed hammered silver with the 3-wing blade and the deluxe later olive green model with timer and 4-wing blade. My only criticism of these fans is the design of the arbor and that you can't easily replace the bronze bushing should they be worn because of the stamped and spot welded metal that is crimped around the bearing. I need to find a good arbor for my olive green model. The 4-wing blade is really heavy for these bearings. The 3-wing blade is really light.

On the Viking, it's a 1 and 15/16th inch diameter pulley. With it being so small you may want to try a cogged belt as they tend to flex more easily and run more smoothly around small diameter pulleys. My Belco Hurricane uses this as its variable diameter motor pulley closes down to an inch and the smaller the diameter and surface angle of a belt, the more tension you need to transmit torque. I have to wonder about the ultimate longevity of these Belco fan bushings because of the tight belt tension on low speed.Bill Fanum wrote: I just got one and I need to know what the motor pulley diameter should be, thanks.

Way to go Chris with the multiple Viking ads!!! Love them!:thumbup THANKS a bunch, they are appreciated and already downloaded to my Viking Archive!:P

I see the ads that have prices seem to be of the earlier versions (Pre 1954) and do seem higher than what I have seen of competing Homarts from the same period. (Not sure exactly how much though?)

I did review your (2) page Popular Science Magazine Window Fan Review and noted the top (3) Sears Window Fans (Not identified as Homarts though, but imagine that's what they are.) range from $57.50 to $67.50 (2) 20" versions and 24". I still believe Vikings sold a little higher, since Sears most likely dealt in much higher volume. Obvious evidence of the greater number of Homarts that survived and remain MUCH easier to find than a Viking.

Thanks again for taking time to post all of the ads. There can never be too much information. Someday I'd like to find or see an actual users or owners manual. Like everything, it exists... "somewhere"? :P

My pleasure! I could spend hours looking at old literature! Yes Homarts were sold in much higher volume. I'd love to know yearly production figures, including suppliers used, but good luck getting any old information out of Sears now. I can't help with the original literature. Would be great to have though.
