I finally finished it! 














It turned out pretty good, happy with it except for the motor tag. Not much I could do with it the lettering was worn or polished all most flush. The paint looked ok when I got it but there was a place right above the switch that was bad. When I tried to fix it I discover that someone had drilled a 1/2" hole in base( probably for a toggle switch) it was repaired with what looked like Bondo with not enough hardener. So I just started over. It didn't have a blade so I got Nick Loos make one for me. That's when I discovered the ammeter shaft was sub standard ( to me anyway .280 in) so Nick made the hub to fit. Darryl Hudson put new bearings,made new oil cups, bearing set screws, and brushes and caps. The switch was home made so I bought a reproduction one from Chad Baker.The cage was a mess, at some point the eight S wires where replaced with nine S wires. New holes drilled in the back ring to accommodate the nine S wires and the old holes where filled with 50/50 solder. So I cleaned them out and silver soldered them.  I installed a DC rectifier in the base. It run great, a little fast for me on 120V, so I am running it on my Variac at 90 V ( just right!) I received a lot of information from members that was very much help and really appreciate it. I have been wanting a Ornate Base Diehl sense I first saw one.

Stunningly beautiful. Tell me about the paint job. It's flawless. Gorgeous and elegant, Bobby! What a pleasure to behold, truly!

That's a beautiful fan. I've also been wanting one for a long time.

So good looking now Bobby.  In fact, WHY does it look so good?  I guess because you did it right and good attention to details.  Had you posted a before photo of the fan?     A lot of work done on that fan but well worth it for a nice ornate Diehl.

I use the Kim Frank method of painting with Rustolem Appliance Paint. I fill with red paddy and Duplicolor filler primer. I forgot about the struts, I made them. Pretty good ! Right

Steve, I sometimes get excited about the restoration I forget to take before pictures. I really need to!

Your restorations are very nice. Did you find parts to put the fan together? If I am not mistaken that base is for a 16" model.

Looks to me like a Coleman motor tag is worth the money for a fan like this. Anybody have an idea what a fan like this would sell for? Or a rough version missing parts?
I would like to see one running, too, if you've got the time.
Cheers,
Bill

I am amazed and humbled when I see the talent in this group. I only dream to ever produce work like this.

This is a beautiful restoration on an incredible fan.  One of my favorites.  Outstanding work, Bobby.

Not the best video, but here it is. I am running it on a variac at 90V with a rectifier installed in the base, 120 V wall power was crazy.

How about the video work! The bearing are new and the brushes need to seat, I think it will be run even smoother.

Cool fan. And good work toning down the voltage with the Variac. Many folks don't realize that rectified 120VAC is closer to 140VDC and could damage your fan if it's not designed to run on that.
I've seen commutators explode. It's not pretty.
Cheers,
Bill

Bill, I did a test using my Fluke meter and reading the voltage at one AC socket on this power strip and on the socket covered with red tape which has a bridge rectifier right under the socket.   The power strip is plugged into a Kill-A-Watt meter which is plugged into the Power Stat.   Did I do this test correctly?
AC reads 120.2 volts
DC reads 115.6 volts

BillActually the voltage does not increase unless you use a filter capacitor to smooth out the pulsed DC. 120VAC actually peaks at around 170V. But...the RMS value is 120V. This RMS value provides the same "heating average" as a DC current. The RMS (average) value still holds true with the pulsed DC from a bridge. If you use a filter capacitor, it charges up to the peak value and holds it between pulses. This raises the average & you will see a substantial increase in measured (average) voltage.

Running our fans on 120VAC actually subjects them to peaks of about 170V!

The voltage in my house varies considerably from 110 all the way to 135 volts.
I think that you might see the pulsed DC smoothed out a bit with the induction of the stator coils and armature coils. Someone with more experience here will surely chime it. (hint Johm McComas) That will fill in the peaks and valleys of the pulsed DC and probably increase the voltage.
In any case, what you usually find is that your motor will run faster on rectified DC that it does on AC and I think the reason is that you are pumping more voltage to the motor.
Maybe I'm just a bit more jumpy about this since I seem to smoke more motors than the average collector.
As far as measuring pulsed DC...good luck getting an accurate reading with your basic DVM. I don't have a setting for that on my meters. Just AC or DC. Perhaps an analogue meter would work better here.
Cheers,
Bill
