So I just got a male/female 14/18mm domeless nail from my lhs for $70. Only thing is I don't know the manufacturer. Neither did the kid working at the shop hahaha. I threw it on my piece and took a low temp dab. I noticed it turned blue/rainbow as it cooled. Does this mean it's real titanium or of a higher grade titanium? My previous nail was a highly educated flux, but I gave it to a friend. I will post some pics in a bit. The second thing is I'm looking to invest in a nice oil rig. The smaller the better. Looking to spend 200-350 max. Was looking at Toro macros and some Hamm stuff. Anyone want to weigh in and suggest a piece?
