Jim Roadt Posted September 3, 2022 Share Posted September 3, 2022 Picked up this mechanical fan, possibly a DeRossi, Blade is coming crank is missing. The blade pictured is not mine and is paper thin and flexible The crank I did find is a tad large looking for one about half that size 1 Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted September 4, 2022 Share Posted September 4, 2022 (edited) Here you go Jim....I roughed it out. Will finalize measurement tomorrow along with the groove and hole for the rivet for handle. No charge for the CAD.

Jim Roadt Posted September 5, 2022 Author Share Posted September 5, 2022 Thanks looks great Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted September 5, 2022 Share Posted September 5, 2022 Done. I made the custom rivet as this is going to be hard to find....friction fit. I also added a piece to the back of the shaft to make it looked hammered and mushroomed out. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted September 5, 2022 Share Posted September 5, 2022 I've added the part to the virtual store. No markup on my end. I did enlarge by 2% to allow for shrinkage and polishing. Steel is magnetic and high strength. My virtual shop (Click to view) Quote Link to comment Share on other sites More sharing options...

They came in 3 flavors of black enamel, nickel, and copper. Four sizes starting at the largest being 10", 9", 8" and no mention of the fourth size. BTW....no mention of the DeRossi name. 🙂 Edited December 15, 2022 by Russ Huber Quote Link to comment Share on other sites More sharing options...
