Several years back, Fine Woodworking had a cool, cheap little trick for veneering. It was right after they'd done an article of vacuum bag veneering... which works great but has a big cash outlay up front. The trick was to apply glue to both the substrate and the veneer and allow it to dry, then use a steam iron to bond them together. IIRC, they used yellow glue (titebond) applied with a roller. For the veneer, they misted the unglued side with water, to keep it from curling from the moisture in the glue. It appeared to work pretty well. They had to play with the iron settings to keep it from scorching the veneer, but, hot enough to melt the dried glue.
