Re: More Pix of Temp ControlEarl, I did this mod two years ago. It was not perfect but sorta works. I had to drill out the orifice on the end of the temperature controller in order to get enough heat. Same symptoms that you are having. I can now get enough heat but the control is soft and not precise. It works though better than without the controller.
Just get a good drill index and find a drill bit larger than the opening that is now in the tip and drill it out. Go slow, go one size drill at a time until you get enough heat. Unfortunately, the bit I used was not marked and I do not have a micrometer. I probably doubled the hole size though. If you goof and go too large, you can always JB Weld it and try again.
