US source of Panzerholtz?

Depending on how much you need and the size you might be able to use USPS flat rate shipping boxes.

Why not order to spec from BDR?

It is fairly miserable to CNC, as well. A bit eating monstrosity it is... with a very narrow range of functional feed and rpm ranges. Delrin is similarly miserable to CNC.

One of the worst combinations, it is: Your sharpest finest bits, with the highest level of bit wear, in the most difficult to achieve ’quality result’ cutting set up. Instantaneous flow of the moment.. feed rate and rpm, stepover, etc, all become critical in the given moment --and the range is small. So you have to change everything in the cutting program to reflect this. Mastering a quality CNC’d shape in panzerholz is an achievement.

Dear chakster, How can different name change the properties
of whatever material? Each language has different names for,
say, the same objects. That is why logician state that names 
have only referential function. Then there is the logical rule that
names miss predicative function. That is to say that names don't
say anything about is bearer. Sorry but I need  for 66 times , as
you pointed out, use as example Vienna. Whatever is true about
Vienna is also true about Wien, Wenen , Bec, etc.  names.
This is called ''substitution  salva veritate''. Each of those names 
refer to the same city. 

@nandric it's a German name for the material as far as i know, in Russia nobody use such name, but we have something similar under completely different name, unfortunately the difference is not like Vienna and Wien (i love that city BTW). It is similar to bakelite plywood ?
