David,

I was impessed by that machine when
I first saw it and have been wanting
to build a copy for a while.

One question though.  How does it fair
with lead free solder ?  Does the 
extra temp bother the roller ?

Also - How critical do you think the 
silicone (? i think ?) roller is to
the function?  Do you think that the
silicone roller could be replaced with
a sprung metal roller?
