Making a few cuts into the copper with a knife may be a better solution, I will try this in the short xmas vacation. <BR> <BR></FONT><FONT COLOR="#000000" SIZE=3 FAMILY="SANSSERIF" FACE="arial" LANG="0"></BLOCKQUOTE> <BR></FONT><FONT COLOR="#000000" SIZE=2 FAMILY="SANSSERIF" FACE="Arial" LANG="0"> <BR>Hi. If you want to save a lot of frustration, I had a local company make some boards based on Johan's design.
