I was told there is a need for this pot metal knuckle part.  Does anyone know how to remove the sleeve bearing?  Is there a set screw?  Need to remove so I can measure to make mold to cast.

Also, is this part pot metal?  Is it often broken?

 I think the bearing is just sitting in there probably stuck from 90+ years of greaseglue. Have U tried soaking it in kerosene overnight ? pretty sure that the pot metal necks worked that way. If that is a rare cast iron neck ,I may be wrong.. Lots of Dayton fans could run again with that neck replaced. I measured for George the rough sizes of different sized fans last nite. Looks like the 12 & 16" fans use the same knuckle. The 10inch fan uses a slightly smaller knuckle & there is a crying need for that piece as well. Great project Louis !!

Yes, I got it from George. Let me ask George if I can soak it...might remove the paint just to get a better view. Hey George...can I soak the piece and remove the paint. The metal will not be damage.

Hi Doc!

I believe it is cast iron neck... I hope it is the same as the pot metal necks... I have 3 shattered necks and this one...

This would be great! The Daytons of this era are a really nice looking fan but so many of them (most?) are needing new knuckles. I know I've passed on at least three that I really wanted to get and would have loved to have added to my modest collection but for that issue.

Dave...if you post a picture of the fan, that would be great as I have no clue what the fan even looks like.

I never have pulled the trigger and gotten one because of the knuckle issue. Here's a string discussing the weakness of this fan with a couple pictures.
http://www.afcaforum.com/view_topic.php?id=59617&forum_id=1&highlight=Dayton+pot+metal

I know when I last looked there had been some folks that had made fabrications. Aluminum, etc. I think Alex Rushing took a Westinghouse knuckle and machined it to work in a Dayton. But I'm not aware of anyone doing any fabrications for some time or I probably would have gone forward. 

I think the Dayton 367 is of this sort although I don't know for sure. 

Here's another thread with another picture of a Dayton, a larger one but also having a pot metal neck.

Finished drawing.  Next step will be to print 2% larger and make the mold.

Buy stock in Daytons. 😆. Seriously though. They’re a beautify fan whose beauty is only matched in measure by the downfall of the pot metal knuckle.

This one was easy to draw up. The opening on top will accommodate modern bearings which is available through Amazon.

Thank you David. I did the calculation for shrinkage base on volume and ordered the print. As soon as I get the print, I will make the mold. Cost for both parts will be around 60-70 shipped.

Hi Louis!
Will the bearing be with the parts or will you have the part number we will need to order?

I'll look up the part on Amazon and post here when the part is ready. The bearing is a standard size. 23mm outer diameter; 11mm inner diameter; 8;mm width.

George, when you get a chance, post a picture of the motor stem...the part where the stem goes into the knuckle.  I could not remove the bearing to study.  A picture may help me figure out what type of bearing is used.

Louis you’re a hero if (when) you pull this off! I’ll be close to first in line for a few knuckles! :-)
