I really believe wood is still the best choice for a vape body. The heat conductivity and capacity are much lower than metal. 120F metal burns you, 120F wood feels nice. Wood is also a lot lighter than metal, so I can do active things without it feeling like a have a brick swinging around in my pocket. Metal is probably cheaper if stamped but requires very large orders to become cost efficient. Machined metal is very expensive. Wood has challenges due to the grain causing problems during machining and also limiting the possible shapes, but is cheap and fast to machine compared to metal.
I suppose I could have made the lock switch from a more durable material. Partly I am trying to push the envelope of what people think wood is capable of doing in a consumer product, and partly because I am all set up for wood machining so it is easy to just make everything from wood. I am confident it will last for years and if not it is easily repairable.
I'll figure out what the lowest and highest temps than anybody will want are. Then there will be a bunch of steps, I'm not sure how many at this point but probably dozens spaced evenly from the lowest temp to the highest. The user gets 3 heat settings (2 clicks, 3 clicks, or 4 clicks) that will start as a default of low, medium, and high (I'll just pick an appropriate level for each). The user can change each setting to whatever heat level they want. So for example, if you using it in a group and afraid somebody will accidentally change the set level, you could set all 3 to the same heat level, that way it is always the same temp. Or maybe you want all 3 to be very hot but just slight variations on hot. It just gives a little more flexibility than the fw5 system. Battery is about the same as fw5, but each bowl can be bigger, so might be fewer bowls.
Yes!
Editing to answer a couple questions from previous page:
regarding smell - hard for me to say because smell varies so much person to person, but I could definitely no smell it if it was in another person's pocket. Maybe some people can?
Yes, the ceramic bowl can be easily removed for cleaning.
Tolerances for fw6 actually don't need to be as tight because of the spring loaded seal between the heater and bowl. All of the dimensions that are important are machined during a single fixturing and mostly with a single tool, so the tolerances aren't too hard to make.
