suggestions needed to put in simple drop leaf breakfast bar?

I need to install a small drop leaf breakfast bar, I only have basic hand tools and electric drills, sanders etc. I am hoping to find a simple plan I can use (or adapt a plan from a bench/table). Not fussed about fancy routed joints.
I was going to drill a wooden strip into the wall with some nice stainless brackets and then attach the drop leaf to that. Then varnish to match the kitchen benchtop.
Anyone know of anywhere I could find a free plan/DIY guide to doing this?
Also are there some special drop leaf hinges that i can use on the underside that would save making special joints etc? I think I have seen something on a caravan hardware website that may be useful but don't know where to find these retail. I am in Melbourne Australia so local knowledge most appreciated. Cheers, Cal.

Answers:
I don't know about a DIY plan, but IKEA sells tabletops that are made for drop leaf designs - and they are really cheap. I mean, $60, all finished cheap. They look really nice too.
