Heh, consider yoursel kinda lucky, cos' here still aint no commercial made wblocks available. Not a single one. Recently I saw the site, some guys making and selling the drilled blocks similar to mine first, and that's about it.
Lucky me, Morphling is very close.
Still, yeah, the fun part is large. Not so expensive for now. I payed for 80 x 400 mm copper chunk somewhat 6 euro on scrapyard. Cutting and making flat woul cost me further 10 - 15 euro, but I'll end up with 7 good bases for wblocks. Dremel cutting wheels, 6 pcs 2 euro. Two good drill bits, 10 euro.
For now...
