VERY slow-going build in process.

Framebuilders Thinking about a custom frame? Lugged vs Fillet Brazed. Different Frame materials? Newvex or Pacenti Lugs? why get a custom Road, Mountain, or Track Frame? Got a question about framebuilding? Lets discuss framebuilding at it's finest.

VERY slow-going build in process.

VERY slow-going build in process.

Hey everyone!

I've been hanging out in this forum for a while now and have been reading up on a lot of frame building tips and techniques. A few months ago I got all the supplies I needed to make my first frame and made a very rough jig with my dad. I attend school in Santa Barbara and my family (and frame building tools) resides down in Orange County. Between work and class-work, I haven't many opportunities to get frame stuff done , BUT on my last visit I got the front triangle done!

Details: the frame is roughly based off of my dad's Colnago Master Art Decor lugged frame. Aiming for the same size (53cm) and geometry because his bike fits me pretty well. Future paint is undecided but its pretty early for that anyways. Lugs and tubes are from Framebuilder Supply I'll get the exact item names ASAP. Brazing was done with silver rod and flux from Henry James.

Jig: The jig was made out of a piece of plywood, threaded bolts, nuts, washers, and a 180* horizontally adjusting welding table (which probably has a more technically correct name) Since its my first build and my dad and I are the same size, the jig does only create one size of frame. The roughness of the jig has already been noted, but the exactness with which it holds the frame is laughably exceptional - we remeasured everything over and over again and it never shifted between mock-ups, flux application, etc.

Brazing: oxygen acetylene

Pictures: Took tons more than these but they're on a memory card in OC! Soon...

Summer is coming and I'll be back working on it soon!

I've been thinking about building a frame for a very long time. I hope you don't mind if I borrow your frame jig design whenever I finally build mine.

I hate to be a negative troll, but plywood is commonly warped, I hope there were 2x4s screwed to the back to keep it somewhat flat. You should have anchored the head tube in two places. I would be surprised if the head tube ends up really parallel to the seat tube. When you go to ride it it is likely to pull to one side, with the crocked head tube. I would have recommended the threaded extenders be much shorter, so you could verify the angles.

Are we thinking that a jig does any more the maintain the geometric alignment? No jig will hold the tubes in planar alignment when heat is poorly applied. Yes, the jig should be as flat as possible to reduce planar miss alignment but depending on the jig to hold this is a fools chase. Andy.
