A lot of the photos I come across of someone showing their conversion process is usually inside their home. Jamie Gossard does it inside his greenhouse and he does alomost 800 at a time. One thing I learned about conversions is that the Tet conversion most of the time will have a shorter scape than the Dip. I thought I had read somewhere that the scapes were usually taller, but I could be wrong. There are various conversion processes and people mix their chemicals differently. Someone told me about a person who does conversions but they inject the chemical into the crown instead of the way the photos show. Not sure exactly how that is done though.
