Louis Luu Posted November 27, 2021 Author Share Posted November 27, 2021 (edited) The top piece was a pain in the butt to draw. I had to do a lot of adjustments to make sure the pulleys were aligned and there is enough clearance. I will need to round off the corners by hand and do some bondo/primer work. At least now the hard part is done with. Edited November 27, 2021 by Louis Luu Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 27, 2021 Author Share Posted November 27, 2021 8 hours just drawing that dang piece...constant adjustments. But it works now. The strings lined up with the pulley with no obstruction and sit beautifully. I will post some pictures tomorrow of how I did this tomorrow.

Louis Luu Posted November 27, 2021 Author Share Posted November 27, 2021 I need to clean up the drawing today for the top piece. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 27, 2021 Author Share Posted November 27, 2021 (edited) Really need a motor tag. Looks unfinished without one. Edited November 27, 2021 by Louis Luu Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 27, 2021 Author Share Posted November 27, 2021 Top mounting piece is done. I still need to round the corners by hand. I like the one with the logo. But here is the plain one. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 28, 2021 Author Share Posted November 28, 2021 I made room on the traction wheel so a rubber O-ring could fit over it. There will be option for 1 wing (without the top), 2 wing, 3 wing and a 4 wing. The "j" adjustment screw sits directly on the shaft to adjust the height of the rotating mechanism. Also, the pulley on the motor is a feather bar...locks it into place to allow rotation and drive the belt. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 28, 2021 Author Share Posted November 28, 2021 I just noticed I forgot the locking mechanism on the friction wheel. Also, need to put a deeper groove on the disc. Quote Link to comment Share on other sites More sharing options...
Bill Dunlap Posted November 28, 2021 Share Posted November 28, 2021 (edited) I'm super impressed. I just want to ask, what size is this device? Is this a tiny fan, or full sized? I also want to suggest using Viton "O" rings for the belt drive. I did a lot of research and experimentation with drive belts with my Coleman vane repros. Viton was the only material with a significant shelf life and it also has good memory properties, and is solvent proof. I can see this black Japanned with gold artwork.

Cheers, Bill My computer is bogging down with the final calculations...I will post in half an hour. The drawings are done! Printing will cost a fortune (close to 700 when all done). I better cast enough to make it worth while. I'll be keeping four for myself. Still calculating. Here is the rough size: Motor will be 125x61x100mm Base will be 78x62xx120mm Top disc mechanism will be 92x32mm Edited November 28, 2021 by Louis Luu Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 28, 2021 Author Share Posted November 28, 2021 (edited) Basically...whole motor will be no larger than the size of a my print paper as this is what I scaled it and used for measurements. Paper I'm using is 8.5x11 inch. Computer is still calculating/rendering image. O-ring will be used on the friction drive wheel for the fan blade mechanism. I put a groove to fit it.

Louis Luu Posted November 28, 2021 Author Share Posted November 28, 2021 Clearance for the pulley perpendicular to the disc plate. Clearance for the pulley perpendicular to the drive shaft pulley. And the rest. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 28, 2021 Author Share Posted November 28, 2021 And the base. And the motor tag plate. And I'm done for the day...back to work. Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted November 30, 2021 Author Share Posted November 30, 2021 I will send out the prototype for printing this weekend and buy a belt for it. I will attached my dremel to the motor shaft to ensure it works before making the mold. I figured how to cut the cost for the prototype...I will remove the bulk of the materials not needed for testing. Once I am happy with the angling and belt works good, I will spend the money on the real print and work on that...sanding, priming, smoothing and making the mold. I wish you can see it...it looks really nice in the CAD program...better when printed. Quote Link to comment Share on other sites More sharing options...
Louis Luu Posted November 30, 2021 Author Share Posted November 30, 2021 The size of the motor is more like a large toy motor but smaller than an 8 inch fan. I would say closer to a 6 to 7 inch. This to me is the ideal size. Similar to an Edison bipolar fan. Quote Link to comment Share on other sites More sharing options...

Louis Luu Posted December 1, 2021 Author Share Posted December 1, 2021 Next phase will be printing and test running it with the belt on and running the shaft with a dremel to test for alignment. Once done, I will make the mold. Quote Link to comment Share on other sites More sharing options...
