Yeah it's called a "reflowster". Check out their kickstarter. It controls a toaster oven. Pretty nice.
Cool, I shall check it out. I'm currently using a hot air soldering method, but when I do board batches I think I may need to try something else.
That reflowster looks great. I am using a electric skillet as a "reflow skillet" and I get superb results recently. I love the stencil you made. You can shrink the stencil outline in a graphics program or if you have diptrace there is a solder paste shrink option.
I just received some Kapton which I am going to try and laser cut my own stencils for the next SMD project. The soda can method also looks awesome (as you did). This is inspiring!
