    head tube problem

    Hi everyone, i just built my first frame. but after filleting down tube to the head tube, i noticed the the tubes were over cooked. so the tip of the head tube got deformed. then i reamed it but the edge is not equal. pics below.



    my worries is that the edge in front of the head tube. - original thickness- 1.17mm.
    what you guys think?

    1.2mm wall head tube for a first frame is a bad idea - you probably should have done it with some nice solid 1.5 or 1.6mm stuff, much harder to distort if your heat control isn't great yet.

    That said I think you can probably safely ride the frame. Stick a headset in it and go.

    Hey;

    If you really would feel more comfortable, you could likely silver a couple of rings over the top and bottom without too much extra heartache. It might not be strictly necessary, but the extra peace of mind might be worth it for you.

    head tube problem

    This happened to me too. I just keep an eye out on the thin walled sections, and after almost a year I am still riding the frame. Your headset may slip fit too without a press in which case get some Loctite 680 and you're golden.
