Great Idea, Marv.

Just about there.  I do my pasting and stuffing on a drafting table and then 
simply swivel on my stool to the left to pop the board in the oven.  So no 
dog to trip over (although we do have seven cats - they stay away when I 
heat up the iron).
For me the tedious time consuming part is placing the components - so the 
suggestion by Ernest and others to cut a parts stencil and just drop those 
little buggers through a hole is very temping.
