1. Getting Down Tube Length - Frame Layout

    With the bottom bracket / seat tube down I can pull the down tube length from the drawing. Carefully aligning the frame over the drawing with the help of a machinist square and v-blocks I can now scribe the lines where the down tube intersects the bottom bracket. Also note, only the lug is only attached to the head tube at this point.![]({static}/wp-content/uploads/blogger/headtubelug.jpg)
    With the frame aligned about the drawing I can scribe the lines where the bottom bracket and down tube intersect. Notch out the lines and the down tube length is done.![]({static}/wp-content/uploads/blogger/downtubescribe.jpg)

  2. Frame Building -ST/ BB Weld Done!

    The seat tube is brazed in the bottom bracket shell. I can start pulling off the rest of the dimensions from the drawing. I am using a reasonably flat surface from and old cast iron table saw.
    ![]({static}/wp-content/uploads/blogger/Downtubelength.jpg)The brazing is not cleaned up yet. Will work on that soon. Also, it is a pretty messy joint but seems to be solid which is what I am most worried about for now.

  3. Frame Drawing - Using the Paterek Method

    Drawing out the first frame. Pretty much completed the drawing so I can get my final tube lengths and cut the final miters.
    ![]({static}/wp-content/uploads/blogger/framedraw3.jpg)Head tube - small frame so lugs are pretty close to one another.
    ![]({static}/wp-content/uploads/blogger/framedraw2.jpg)Bottom bracket shell will dictate the angle of the down tube. I am struggling with final alignment of lugs/tubing but I think a lot of cold setting and lug prep will do the trick.

  4. Finish the Notch

    ![]({static}/wp-content/uploads/blogger/filenotch.jpg)File the finishing touches on the tube. This is the most tedious part of all but the snugger the fit the less chance of frame distortion.

  5. Rough Scribed Lug
