I heat treated most of my smaller tubes in the oven. I had mostly pre-cut these to be Chainstays and Seatstays. The bigger tubes for the main triangle I cured with the hand torch. After the heat curing I put all the bamboo in my bamboo drying house for 4 months or so (my sons tree house). So as for a strength test comparison of torch to oven, it would be an apples to oranges test. They all seem WAY stronger than the green fresh cut stuff. I just built my table jig this weekend and glued my seat post steel insert into the top of my seat tube.
