I keep thinking it might be easier now (2023) to do a lugged frame than it was 10 years ago because… You can design the frame with a CAD program, design the lugs with the same program, and print the lugs using a 3-D printer. If you don’t print the steel lugs themselves, you can use the 3-D printer to print a wax lug, which you can then cast in steel. Suddenly, everything fits. The lug fits the geometry of the tubing. If you make a bigger or smaller frame, it won’t be “we only have lugs for a 55Cm, but this is a 60Cm”, because the printer can just print the correct lug.
Having spent 45 years working in aviation, I know that the skills required to weld/braze thin walled steel tubing are every bit as demanding as brazing on a lug. And the CAD tools today are outstanding. -- You received this message because you are subscribed to the Google Groups "RBW Owners Bunch" group.
