BP are casualtys of reacent updates, so they be back soon ya just go scraping, and for blower it realy depends on the size of your pot and how big the stuff you are forgeing, i personaly only do small stuff right now, like no bigger than one inch so i can use an industrial hairdryer and blow it into a dryer exaust tube then into some gas pipe from plumbing in home depot, and that get my stock to a nice light straw color. but realy anything that blows air will work, i think there is also a BP on making bellows...
