Brazilian Rosewood: 305f
Cocobolo: 310f
Koa: 300f
Paduk: 310f
Walnut: 300f

That list looks a lot to me like 300f +/- how long has this thing been heating up?

Most of the woods on that list start to give a long way before 300f, more like once steam starts to form if you've used some minor amount of wetting. I don't know that I've ever gotten anything on that list to anywhere near that temperature (except Padauk). Walnut starts to bend at close to room temperature if you just tell it to. (well, sort of ... :lol: )

Now Padauk, on the other hand ... How hot will this thing go?

The degrees shown are not the temp I start bending but rather the max temp I let them sit for a minute or so. I start bending around ~230

It only takes it about 1 minute or so to get to ~230 (probably less)

All of this is explained in the article should you care to read it. The numbers were based off ones I learned while working for Dana Bourgeois. I altered them slightly, although it probably doesn't matter too much.

Sorry if I caused confusion. The article explains John's process in detail and I should have been more explicit in directing people to it.
