hmmm... try it from www.hot.ee/sonnich/lego/ for IE you can use the back
button on the menubar (the little down arrow to the right of the button) and
select where you want to go back to.
Anyway, I will look into a more reasonable solution to this.

I have never boiled lego, but it should be more than 100 degree celcius
AFAIK. And bismuth as I use has a melting point lower than that, som 80-90
degrees (depending on the type).
But just putting in into a lego brick cools it down quickly, it you don't
get it right the first tine you can start over.
Luckily a soldering iron can melt it and you can get it easily.
The bricks do get hot, my expirence is that putting a brick under it right
away is a good idea, otherwise it might widen a little.

I only have access to that a few times over the year and the process is
timeconsuming. So, no, sorry, I have no plans for selling these.
Next time I have a possilility to do this is in the end of July, I might
look into somethig then. My hope is for tommorow to get 8 3x2 blue bricks
prepared for this. If that succeeds I might be able to make more.
Also no to forget, Adrian Egli suggested to use plates under the tracks to
make the curve turn.
