Not doing a 3d mock up of this one... too late and bout to pass out.. but here goes the base description. 

All this can be bought at Home Depot, Lowes, etc.
You'll need:
3 24"x24"x1/4" pieces of thick lexan, hard plastic sheets, or wood.
1 protractor
1 Dremel, or router, or a lot of patience because you're gonna be cutting slots and a box cutting tool might take a while.

Blah... going to tell the lazy way from here on out... really lazy.. but it wouldn't take much to beef this up...

You'll need some twine... and a bag of heavy duty rubber bands...
what we're basically doing is taking the protractor and drawing a circle in the middle of the hard plastic... take a pen and place a dot ever 10 degrees on the protractor.... take a ruler and start drawing lines from each degree to it's opposite degree. 

You should now have something that looks like a hard piece of plastic... with a circle in the middle and a bunch of lines coming out of the center...  yay.... sarcasm.... anyways... starting on the outside of your circle start routing the lines away from the circle.  Try to be as centered to the line as possible. 

Now we're going to take one of those other sheets of plastic and our ruler... trace the shape of the ruler.. cut it out... use it as a template for the others if you want.... and place 2 small notch marks at the 11" line.  Now cut out 36 of these.  Really getting sleepy now...  what we want to pull off is stand each of these up in the slots...do this by cutting rectangles (2"x6"x1/4") out of the extra plastic and screwing those on base of the 36 shapes you just cut. 

So now we have a board of some material with a circle... slots at every 10th degree... 36 "Fingers" with bases screwed on the bottoms of them.... Flip the main board over ..place a screw dead center of it... drop the "Fingers" so they're hanging from the base... add screws to the right and left side of the base... attach rubber bands from those screws to the one dead center of the board... this will be the anchor...  now when you flip it over you should have 36 fingers sticking straight up..... with notches cut out at the 11" mark..

What's it supposed to do?  Well.. since this is the extremely lazy way of making this contraption... you'll place your toroid at the 11" mark... since the board is slotted the fingers can expand and contract based on the size of the toroid... so as long as it's not too big or small for the device you can put whatever toroid you want and always have the 10th degrees ready for you...

Use the twine... tie your toroid to each finger using the notches...  if you built this secure enough you should be able to wrap your toroid at a MUCH faster rate of speed.  If you're not digging the twine idea then I'd suggest using finishing nails mounted to the "fingers" to bore into the toroid and secure it.


Either which way you'll have both hands free and if you use the idea I posted with the "Wire Handler" you can focus on making the perfect coil. 

Yes... I went lazy.... I know... I'm not sorry though... if you're one of the people who didn't have this idea then maybe you can build on it... make it better.
