@woodstove-
Funny, I've always found transfers to be trickier than the lifts. It's usually tough to get a really nice transfer without losing bits of the emulsion whereas with the lifts it always comes up in one nice piece- at least for me.
Here's how I do it: Expose your photo, pull through rollers, develop as usual. Then wait overnight. I have lifted right away, but I have much better results when waiting at least overnight or 24 hours. It just gives the emulsion a chance to really solidify. Then, hot water. Not boiling, just hot from the tap works nicely. Dunk the print, let it float for about 5 min to loosen the emulsion layer. While this is happening, get your receptor paper (or something else - glass is great for these) ready. After a few minutes of the print being in the water it should slide off the polaroid paper fairly easily. If not, give it a few more minutes- don't force it or it will tear (can still be nice!). Once you have the emulsion off the polaroid paper, leave it floating in the water and put your receptor paper in too. Slide the receptor under the floating layer of emulsion and work it around to position it where you want it. Then slowly lift the paper up so that the emulsion 'lands' on it. Before you pull it completely out of the water you can reposition it slightly to make ripples, smooth it out, or however you want it to look. Then take it out, make sure it's adhered well, and hang to dry.
