I did not intend to tease, these are just plain facts and informations about the heating station.
I can`t make a video about it now as we are still waiting for the circuit boards to arrive, it shouldn`t take that long from now. We could show how the prototype works but I want to show the final product in order not to confuse things as interent never forgets. Before I accept any pre-orders, I want to hold that thing in my hands and be sure everything is ok. My word, you will get one

Thank you.
I am aware that the stainless steel filter erodes the center pin eventually as copper is softer than steel. This is nothing new, the only question is, how long will it take or how many times does it has to be used for this to happen. From my own experience I can say that it takes quite a bit to erode this pin to the extend shown on these pictures. Then again, I have to admit that I am not 100% sure if there are some filters with very sharp edges enhancing this process. With this question in my head I just placed some filters under the microscope (50 times magnification) to find out.
Beforehand I have to explain that all the filters get a vibratory finishing after the punching and bending process in order to eliminate sharp edges. Looking at it through the microscope, it is hard to imagine that pins get worn that badly in such a short time as I could not really find any sharp edges.
Of course I did only check a hand full of randomly picked filters, it does not prove anything.
What could we do to rule out this to happen? A steel pin in the center of the bowl would solve this problem but it would make vapman more expensive. As this is not really a big issue, I like to avoid anything making vapman more costly in the production. Switzerland is already a very expensive place making it hard for us to compete as by far the most vaporizers are made in China.
May be extending the vibratory finishing process on the steel filters helps. I think this is what we will try first as it doesn`t add much to the costs of production.
In the mean time I advice not to apply unnecessary force causing more friction when locking the upper part on to the bowl. Especially locking and unlocking vapman just for fun to hear the clicking sound (as I do sometimes
) should be avoided.
Again, even I now wrote a long post about this topic, the center pin is not a big issue on vapman, normally it takes many many years to wear down the pin.
I have to go now, I will do a post about lighters very soon as this is also a much talked about subject and very important for vapman.
Thank you,
