I got all excited to make one of these, and did some research.... First just buy one, bit spendy for quality. Second the concept, Apparently temp control is a big deal in controlling heat, (and different suck tips for different projects, and maintenance seems to be a constant battle beings the solder has to go someplace,....On a budget the arrow seems to have some good reviews at around a buck and a half. Jennifer for now will probably just stick with her solder tape as it has served me well ,.... Thanks for the plans though Pbj, it is a fun idea.
