First we crawl, then we walk, etc, etc.... Sounds like you're a much happier camper. Not to point out the obvious, but... what about putting your oven toward the rear of the workbench right in front of you and building a little platform to hold the board while you populate it? The top of the platform should align with the top of the oven rack, touching it where the two meet. That way when you're done getting all those teensy-weensy-itsy-bitsy-tiny-nerve-wracking components placed you can just slide the board into the oven. At least it would keep you from tripping over the dog, dropping the whole schmear, or otherwise endangering the fruits of your labor. Just a thougt.

The second board turned out much better although I still had to work the 0.25mm pitch socket manually to get it acceptable. ...snip... After I did the solder past run, I removed the solder on the .25mm pitch 30 pin socket as it has "slumped" and covered several adjacent pins. Flux may have seen it draw onto the pins, but I think there was just too much and it would bridge again. So I removed the paste in that area before popping it in the oven. """
