Miniature coil winder
« on: October 05, 2018, 02:34:46 AM »
Ok going to build (or attempt) to build miniature coils first need to build the winder. I'll post here if there is any interest in it if not no big deal we will see.
Anyway the first thing will be the gear package for it. It will be a version of the Side Winder miniature coil winder from Bob Shores book.  The book is a very good book if you want info on coils and windings  I recommend it.

Ok setting up machine to cut gears for the winder.

There are several gears needed all are 48dp  need one 16t three 32t one 72t and one 81t. Going to start with the 16t then the 32t after that probably the 72t as my indexer will index even degrees. For the 81t I may set up the machine to make my index strip for me first. Sure wish I would have gotten the A  axis when I got my machine. That would have mad things so simple oh well I always said I like a challenge. Haha


Anyway here is a video of setting up machine.

Ok cutting the first gear a 16t x 48dp  After this I will cut the 32t then the 72t and last will be the 81t. But before I cut the 81t I will set up the machine to create my index strip.

Here is #3

  Cool Doc I had started to build it years back just to do it but will watch your progress. Bobs book is a great book to read.  :ThumbsUp:

 Thanks Don wasn't real sure if anyone had any interest in this. I am more or less just building it to satisfy my wanting to see if I can do it or not. I have always been fascinated by electronics and electrical things (I know just enough about electronics to get into trouble). I sometimes think about taking some class's in it but never do.

Hi Doc,
 Following along, unlikely to make the winder, but interested in gear cutting & that sure went easy!

Cheers Kerrin
Get excited and make something!

Still not done with the gears have the larger ones to do yet. I think I'm going to make a spring loaded pen for my machine and let it create the index strip for me, The lager gear is 81 tooth. So I'll take my paper strip length is (5.04 the indexer dia x 3.1414 = circ) and let the machine put the pen marks on it for me. I took an old pen and put it into a tube that fits the 7/16 machine collet and JB weld. Then take the ink cartridge of the pen and make it spring loaded. It should work we shall see. The JB weld should be set up in the morning so I can move forward with the plan.

Preparing to cut final gear for build. Set up and let machine create the indexing strip.

Ok I setup machine and machined the last gear so the gears are completed. Next I'll start on the side plates and spacer block. The gears went pretty good. I'll have to remember to do my index strips like I did this one sure beats laying them out by hand. If I was still working I could have plotted them out on the plotter but the machine came through for me and did it correctly. Any way here is some clips of the last gear getting machined.

Tested the transmission gear train with a small 12v dc motor. And here are the results.

Cool Doc you made a lot of head way on it. Are those motors from a swivel sweeper because I have a few of those?  :ThumbsUp:
