Not a lot going on in the frame building front. Working on getting an alignment table figured out before I can go much further. Will probably not get the frame complete by the time I go to the Handmade Bicycle Show in Feb.
My first brazed lug! I bit more brass than I probably needed so the cleanup was a bit much. I do think that the penetration of the joint was good though. I did some cold setting on it and it did not flinch. Overall I am pleased with the newbie attempt.
Going to find a source for “blemished” lugs so that I can practice a whole lot without breaking the bank.
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.
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.
Drawing out the first frame. Pretty much completed the drawing so I can get my final tube lengths and cut the final miters.
Head tube – small frame so lugs are pretty close to one another.
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.
Went old school and picked up a drafting table to hand draw my bicycle frames on!
Details and pics coming soon…
