I recently recieved my new custom built steel frame, but have a few issues that I need some advise or opinions on. I know that I should contact the builder and I will as soon as I feel better educated about the issues. As you can see from the photos, first the brown line that is at the seat tube bottom bracket intersection is a mystery to me. I can't wipe the brown line away with my finger or a rag. Not being a frame builder, my thought is that there is not enough silver brazing material in the socket or a pin hole which results in framesaver seeping through, hence the brown color. Another photo is of the downtube,headtube intersection. As you can plainly see there is a gap. In my opinion, this is not normal for a hancrafted lugged steel frame in which I paid about 2k for. The other photo shows the powdercoat finish, or lack thereof on the lugs. Could some experienced frame builders please give me some insight on these issues so I can better speak with the builder?
