Happy Robot fan is still for sale.

Ebay is charging so much these days. If something doesn't sell, you still get stung pretty hard.

See it here . 


Cheers,
Bill

  Hey Bill , those are darlin' little fans. Looking at the way you made the blades , I'm wondering if you could reproduce the little 8" Emerson Trojan all brass fan blade if you had an original in your hand to go by ??  I've got enough parts in a box to put one of them together... all but  the blade.  Is that something you'd consider fabricating? Wish I could sport the pair of those up here in the Ozarks but I sit here recovering from a back operation while the overhead clock just keeps on ticking at my office.Sad state of affairs it is , Cheers/Blessings , Geoffrey D.

Geoff,
I think I could make that one. I've made several Westy all brass blades in the past. I had a steel one to use as a pattern.
Getting a pattern may be the difficulty. The best scenario would involve having, say, a damaged blade I could press flat to make a tracing from.

That may be too much to ask, though.

So, barring that, some dimensions and good photos would suffice to make a replica. It might not be an exact copy, but it would probably pass OK.

And get well soon. I know it would drive me absolutely nuts to be stuck in bed for more than a day.

Cheers,
Bill

I’m a pretty sharp draftsman and have 30 yrs experience as a CAD designer, I can draw that up and convert it to whatever file we need for CNC milling. Oh whatever process we need. Just as when Steve Austin was being built we have the technology

The process to make the blade will involve;
1 Sourcing the material
3. obtaining a sample or dimensions
4. Turning the hub on the lathe
5. Drilling and tapping for set screw
6. cutting out the sheet brass for the blade
7. rolling the radius in the wing
8. assembling and swadging the blade and hub together.(I usually solder them too, just for more security)
9. setting the pitch
10. balancing the whole assembly
11. polishing the assembly
12. cleaning the assembly thoroughly
13. Applying clear lacquer.
14. rechecking the balance, test running on a fan and correcting for fore and aft run-out.

It's actually simpler than it seems once you've done it a few times.

I'm perfectly happy to do this for the members here.

Cheers,
Bill

Geoff, Bill,

I don't have an all brass Trojan but I think Robbie Lawrence does. I'm sure he wouldn't mind tracing the blade and sending you a trace of it to help. I just texted him.

Jamie,
That may be the way to go. I wouldn't mind having a CAD file made up for it, but I'm afraid by the time you paid someone to water jet it or plasma cut them the price would be too high.

It would probably be the kind thing to do not to have Geoff fussing with things at the moment.

Cheers,
Bill
