Need plans with dimensions and photos to build an outdoor pig roaster
out of wood. NOT BBQ PIT OR METAL SPIT. I am looking for designs in
the style of a caja china, chinese pig roasting box or cajun
microwave.

I made one (a pig roaster) and it did not get hot enough and I'm
looking to fix it. I'm trying to find actual plans to see where I went
wrong? My design called for making a 2x2x2 wood box and to place a
metal ash pan on top. Fill with charcoal and cook a pig underneth.

I do not need links to retail sales of bbq grills. I would like links
to web sites or discussion groups or links to willing experts to
discuss my problem. I'd kiss you if you provided links to actual plans
I can print!

Make wood box approx 12inches tall by 5 feet long by 24 inches wide. 
Use straight cuts.  Cover the inside with flashing.  For the top cover
make a wood frame using 2x2, make sure that the longer pieces are
about 6 inches longer on each side to server as handle to lift the top
cover. Then cover the frame with a piece of zinc cut to size.  About 4
inches from each side add a 4 inch tall wall of zinc to hold the
charcoal in place. On one end of the box leave 6 inches (the width of
your shovel)without the wall so that you can remove the ashes form the
charcoal.  Additional tip, on one side of the long strip drill a small
hole to place a thermometer.  Make sure that you cover the area so no
heat comes out thru the hole.

Sorry but forgot to tell you to add four pieces of 2x4 for feets. 
Make sure the height is perfect.  You can also add handles and wheels.
