Some time ago several AFCA members expressed interest in the possibility of me producing replacement plates for Emerson oscillating fans which used the earlier version ball-detent oscillating wheel.  Many of these style plates have broken over the years because they were made of casted zinc and by design were very weak in the bridge area.  I have since, after many hours of design, tooling procurement and preparation, been sucessful in producing small runs in both the large and smaller plates made in steel.  These plates were modeled from original Emerson cover plates and use the same screws, spring and ball-bearing, and, are very robust and durable.  I have also tested my plates for fit and function with good results. There are very many close tolerance machine operations involved in making these parts and my pricing for these is firm and will be $40.00 each plus $5.00 shipping. 
Words of caution!  In case you have never removed the cover screws and taken these original cam wheels apart or re-assembled them,  I would recommend doing this very carefully in an enclosed area as the spring and ball bearing easily will shoot out and be hard to find.  After several spring and ball bearing searches, I develped a successful way of doing it in a safer manner.  If you decide to purchase a plate, contact me if needed, and I will tell you how I did it.

Thanks, Jerry Bravi

Lucas,Thank you for the praise.  It makes me feel that the work is worth the effort when members respond with positive comments.  We have to keep these old fan going!

I need to check mine to make sure I have all the other parts and that this plate is all I need, how about the shoulder screw? I may be missing that as well. Great work, I have been wanting a working oscillator of this type for a long time.

Mike,When you say shoulder screw do you mean the 2 screws that fasten the plates that I made to the cam wheel?  If so, they have standard threads, 6-32 for the small and 8-32 for the large.  The only difference from being a standard screw is that the screw heads are slightly smaller. If you need 2 screws to go with the plate, I can reduce the heads of 2 screws for you to fit the plate.

Thanks, Jerry

No, to my knowledge those aren't shoulder screws, at least there is no reason they should be. I am referring to the screw that connects the oscillator arm to the wheel, that screw needs a specific size shoulder on it to accommodate the thickness of the arm.

So I was able to find the shoulder screw in my parts bin but I looked at my broken wheel and since It was broken before I received it the spring and ball are not present. Wouldn't this be the case for most people who have this issue? Whenever the plate breaks I don't see how the ball and spring can be retained. Do you have these available? I'm not certain but I would imagine that a person needing this part would also need the ball and spring. If you do not have them maybe we can source what is needed and group order it?

Mike,I do not have the balls or springs for these ball-detent cams.  The small ball and spring measure approximately .156" diameter and for the large size, the ball and spring measure around .219" diameter.  I'm thinking that these items could be obtained through McMaster-Carr.

So went ahead and ordered 5/32" &  7/32" balls and springs. Now I do not have them yet so I cannot be sure if the spring will have the correct tension and if everything will fit correctly but I will test out the larger size when I receive them and let you guys know. I do not currently have the smaller size wheel to test the ball and spring on but I did order them. If anyone wants a set, message and I will drop them in am envelope. I ordered the springs in the 1" length for the larger size wheel and 9/16" length for the smaller but I am sure you will have to trim them to length.

As usual the work looks great!  Thinking of all those broken assemblies that can now be repaired with these components.

Very nice work Jerry.  I will be ordering some soon.......need to check my inventory.  Also, I made a simple tool to retain the spring and ball during assembly, but I will have to find it before I can explain it.

Thank you Tom for your compliment and also thanks to Chad and Dan for their recent posts!  It makes it easier and more satisfying to make these type of replacement parts, knowing that their are people who understand and appreciate the amount of the work and effort it sometimes takes.  

Please just let me know when you decide on the ball-detent plates you need and I will get them out to you.  It sounds like you had to chase a few flying springs and ball bearings too.  Everyone will appreciate your simple loading solution when you put it out there.

Best regards, Jerry
