Hey Bruce!
I also want to thank you for all your inputs – really helpful! 🙂
What you mean by filing the foot is to make the bottom side completely flat, right?
Did you do this by hand? Is it hard to do?
I also work with the Jingda-Iron and so far, I’m happy with my results (hadn’t much time to built yet though).
I checked the temperature with a thermometer and found that it’s always a little bit colder than it is supposed to be. When set to 225°C you actually get ~210°C which is a good temperature to weld in my opinion.
I’ll get my hands on the following iron soon and will review it here as well:

The display with the iron-temperature could be a nice feature…
