Father/Daughter Project - Part 18
Thursday, February 13, 2020 | Chris Blandford
All right, let’s get this little frame off to paint. To finish up:
22. Make and braze-on headbadge
23. Fill pin-holes (if needed)
24. Drill BB vent hole
25. Final soak and clean up
I designed this headbadge, primarily, so that it’d be easy to make and braze on. I cut these out of regular, .058” tubing (the same used for the head tube rings). I print the logo onto sticker paper, cut it out, and stick it to the tube. Cutting wheel, then small files.
(Those first couple photos were from a previous project, but that's the idea.) Clean, flux, and (silver) braze. I’ve just lined these up by eye. No pins or special fixtures.
Next, I go over the frame and find any pin holes that need filling. I only started doing this recently, after I listened to an interview with Rudi from Black Magic Paint. The last person I want to think poorly of my bicycles is the person tasked with painting them.
I fill any pin holes larger than the head of my smallest drill bit. I drill them out, flush with isopropyl, flux, dollop on a bit of silver, and sand smooth. On this frame, I filled two holes--one on the dropout and one on the stem.
Finally, I give the frame, fork, and stem one last soak in my ultrasonic cleaner. Then I remove the pieces and go over each with red Scotchbrite. The metal turns rich and dark while soaking. Bringing it back to shiny forces me to look at each spot of the frame and make sure I’m not forgetting anything. I know this isn’t necessary, but I like handing off decently clean parts to the painter.
That’s it. Off to paint. I dropped this off at Black Magic last week.
Next: I'll share the paint scheme, get any needed parts ordered, and--finally--start in on the Father frame.
