Take a thick ziplock bag, and fill a corner with kief. Heat a butter knife (one you'd use for knifehits, because it will be discoloured) with a lighter, but not enough to melt the bag, and press it down as hard as you can on the corner, on a firm level surface. And rock the knife around to really press it all. You now have a little hash chunk.
I forgot to say, with the rotary coffee grinder trick: Just like with any kief catch on a hand grinder, remember that it's always cool to let people use your grinder, but not cool to dip into the kief of others, even if it's not a conventional type of catch. People often like dumping their weed in when they come over, because even though it's not the world's greatest grind, it's fast, easy, can grind a lot, can grind it to whatever courseness you want, etc. So let them do it, but make sure they know scraping the top is a no-no..... and watch the hash flow into your stash
What I said all basically. Nothing I know about "ice hash". Just grind up your bud a few times and leave it in there with a dime. Put it in the freezer for 15 or so and when you take it out shake it up and hit it downward on a surface. Then you're done. Not sure where to find a good grinder online.
Whoever doesn't use a grinder, is a noob. I've been using some sort of grinder with a kief catch ever since I started smoking. There's no real excuse not to. I got my space case with 2-stage kief catch (1 normal catch, then a finer screen for 'top kief') and a pollen press for only $20 shipped off ebay, so its not that expensive. And besides, with most kind bud you get baked as fuck anyways, so you don't need the kief right then. Its NICE going completely dry and still having kief and vape waste to pack a bowl with. And its nice because it smokes like hash and gets you retarded all on its own, without having to buy more weed.
