Finally got around to getting progress on the buildup. Had a stuck seat post that wouldn't budge. I had already soaked it in deruster with no luck, next was propane torch and atf fluid but that didn't work either. The whole problem was a small bend creating a lock right in the center of the frame and it was one super long seat post. Busted out the hole saw instead, after not having any luck. 2nd to the last option was Maacos frame machine. lol! Pulling any harder would have trashed the frame. Last option- Acetylene Brazing, Not having done this before I went ahead and tried it for the first time. First up,chopped it on top going past all the old brazing and its also my first time cutting an old frame too. Loll! Didn't want to mig weld it- that would be cheating, So, I hit the pawn shops and struck a deal on a mini torch setup and watched a bunch of YouTube vids on bicycle brazing techniques. The donor bike for the seat tube was a old girls flower bike Murray- for anyone wanting know. Well..Did it, Done it....Thats it for this week and we will see how the paint comes out this weekend. This is a sons and father project, my part is complete ha! They will paint and snap it together.
Using a tube cutter to make a nice and straight cut then filing it clean.
Drawing marker lines for the seat clamp notch.
Finished notch.
Used quick steel to fix any minor imperfections on frame.. bumps scratches etc. Then sanding down with a flat file and 240grit.
A little progress, sprayed strip clean to remove old paint. used files, Dremel, and wire brush to clean the brazing. All thats left is removing the fork and cups for spraying a nice coat of primer filler and wet sanding.
