Hmm,

This is worth trying as an experiment, just to see if it will work, if it does then we would have some moden material that others could use too.


But make a stubblefield coil out of the cotton covered wire first so you have something to benchmark it against.

Stubblefield said his coils could operate in the ground for years with no problems.  I don't think the cotton will rot as there is no air to get to it but, an experiment is always good, then we will know.

@ all,

Just a reminder, lets keep this thread just on the Stubblefield Cotton Winding Machine and the mechanical components it will be built from.

I don't want to take away from the LocalJoe Stubblefield thread anything related to it here. ;)

Got my Thread - Cats like Thread.
Weighting on my pulleys.
I have found some likely pipe for the shaft but then I need to have the pulleys so I can get the bearings etc etc
No pulley pairs at scrap dealer yet so I wait.

Got my Pullys.
I am seriously thinking of cutting them (Or one of them) in half.
I would then have a thiner setup overall like you suggested Jim.
I will run in to town tomorrow to check the availability of Bering sizes.
I'll stop by the machine shop to check cost of cutting a belt notch.
May be able to do this myself but if they can - all the better.

You are doing well there FrozenWaterLab.
I'm looking forward to your results, take it slowly, saves mistakes.




I got myself a very old lathe last week, got it home and it was so heavy I had to pull it apart, (my small home made jib crane came in handy) to get it where I wanted to use it.
Unfortunatly there is no cross feed screw or gearbox, well the price was about 1/4 of a lathe with all the bits attatched.
Now I can make some special parts I will need for a stubblefield winding machine.

Hay that's great Jim.
I'm seriously Jellious.
I was looking at the Tools at Alaska Industral Hardware last week.
Lets see now I could sell the truck and the house haha
Havent been to the machinest yet. But I have dug holes in the back yard for some EB Experaments. I'll be posting a blurp on NSEB in the next couple days.
I'm way behind youall Page 118 but readin as much as I can. Want to get these basic battery tests done and move up to NS Bat.
Next tuesday I'm hopping to go to the Berring Engerearing Store in Anchorage and see if I can get what I need or order them. (Outer rings are there need roller sets)

Today I got back to making some more parts to add to the Cotton Winding Machine.

I needed a support bracket and central shaft to take the weight of a roll of bare copper wire. I bought a 6mm dia gal bolt from Mitre10, welded a 6 inch bolt, head to head and when the bracket was made, I welded it to the sub sliding frame.

The idea is, I undo the long bolt, remove it, put a new roll of copper wire in the bracket area, thread the long bolt through and tighten.
The weak compression springs and big mudguard washers keep the roll of wire central to the main axle feed hole.

Below is the photo of the support bracket assembly.

What is a mudguard? (ausie speak), keeps the mud from the tyres splatterring all over the shiny car, you yanks call it a "fender", but why? ;D

Here is a photo of my range of cotton threads to be used on my cotton winding machine, I have a few more somewhere but have misslaid them.

So what are gentlemen doing mucking around with cotton rolls? making energy, eeeeeha.
For those who want the GIANT rolls, the label tells the tale.
