 Hi folks , been bummin around the ozarks cause I wasn't at Ackley & bluer still since Lake Houston ain't in the cards either this year , thought I'd update an ongoing project we'll be working on in November.

  Last year I showed these pic's and asked if anyone could ID the remains (forensic fanology is great fun)

 Then , conferring with Jerry Henry , Randy Rohr and old Emerson literature , we determined it to be an early 820. The blade remains went to Paul Graves. The fractured base went out to Silverton Foundary then once duplicated was used as a donor base to repair the original. That brought us to this point by late spring of this year.

That's amazing Geoff. It's nice to have friends with powerful lasers. Please keep the photos coming as you get the fan further along. If I remember right this is the only 16" Emerson with bullwinkle blades?

  Mr. Graves copped a switch for it at the barn sale in Rockwall. He will shrink a 16" cage to fit this 15" 133 cycle motor. As soon as I get the wire size to Bill Fanum , we'll order the necessary magnet wire and if , lots o' ifs , Sparky makes it down and takes the 133 cycle converter out of his trunk this year , we might see this old fan run.

Footnote , This project is one that Dan Havner , former AFCA photographer had intended to complete but never had all the resources gathered to do it prior to his untimely death in a house fire in KCMO 5+ years ago. This one will indeed be a tribute to him.

Ahh, I was curious on why that motor had 8-poles but now I see it is a 133 cycle. Nice work so far though! :up:

Geoff that fan will be something to behold when finished. I love the lengths you are going to to restore it

Switch is not correct.

However, good to see you've finally cleaned up the shop.

I'm certainly planning on coming, and will bring the multi-cycle magic box!

Rod, will your magic box output 30 cycles? How does it work? I need 30 cycles for a Century skeletal which runs great on 60 cycles but very slow and fairly hot after a half hour or so.

Geoff,

I have two 133Hz Emerson's of this vintage and they both run great on 60Hz. (no heating either), at around 750 rpm. I had to do a little tweeking of the start switch though.

I use a signal generator and a big power amp for my VFD. At 133Hz these beauties turn up to nearly 1775 rpm- too fast for my slow paced life.

I applaud your commitment to original restoration. Perhaps I'll get there someday.

Regards,

Randy Rohr

Well Doc Geoff you have truly outdone yourself on this one and in fact when you called me back some time ago and we discussed this being a big 810 which I had and understood, I wasn't truly sure we pegged it correct until I visited you in April for an up close & personal look & touch exam. I truly admire your efforts on this one as its somewhere between a Rehabilitation & Reincarnation. In fact I would have bet half my Stimulus Check that the old timer would never blow again!

Guess I'll just have to see you in November as I feel a Fan Fever coming on..  BRAVO MY FRIEND, Jerry Emerson

Yes, it will do 30 cycles. It's an electronic motor drive for small machining equipment to control the speed of the cutters. Think of it as an AC powered inverter with programable frequency & voltage.
