I am getting ready to try to make my first set of slot/stitch rings. If I make my slot 1mm or something similar that is very small, what is the best way to get the wood consistently this thin to lay in the slots?

For many years, before I obtained a CNC that now does the task, I would mike the glued up veneer stack, then use a standard size end mill (.031, .062, .125 or such), but less than this width. I would make my initial pass to depth and then rotate my indexer a degree or two so as to make the width of the cut sufficient for the veneer stack. I had a Atlas lathe set up and only using a indexer and tail stock, but not the chuck, I could cut these pockets under power. I now just draw a program and use either a .0312 or .0625 end mill to cut the slot to perfect size. Technology is truly wonderful.

Where is it written that you have to use epoxy?
Nothing is cast in stone.
One important thing to remember with epoxy is that the more you mix in a cup, at once, the more heat it will generate from the curing process taking place. The more heat, the faster it will start to setup. I have found that the smaller the cup diameter, the more heat buildup. If you use a bigger cup, and still mix the same amount, it should last longer before starting to get thicker. Also important is that you measure the hardener to resin ratio as close as possible. It can mean the difference between curing too quickly, curing perfectly, or not at all.
I haven't used Titebond yet for rings so I have no input on that. If KJ suggests it, then I'd give it a try. I personally would only use it for wood to wood or wood to fiber stuff, not on metal or plastics.
Enjoy,
