I started to create a number of circuit boards with surface mounted components. Though I had a CSI 825A SMD rework station, soldering micro-miniature components was starting to take up too much time. So, I researched solder reflow ovens and found one by www.whizoo.com that looked like it would work and cost me about $200-$250 with my modifications. The following is a photo montage of the end of the build. WARNING: If you try this at home wear leather gloves when disassembling or handling the disassembled oven or there WILL BE BLOOD!!!...and yes there was!!!!!
