Re: [RBW] Re: "A Steamy Lug Affair" by Grant Petersen

Two observations from reading the article. 1. The lugged bike renaissance happened and is ongoing. 2. Neither of my two Rivendell’s are lugged. Well, the Clem has the seat cluster… Sent from my iPhone On Oct 5, 2023, at 5:05 PM, Ted W <ted.l.w...@gmail.com> wrote:  Funny you should mention this I have a couple different 3D printers, one that prints in resin which is perfect for making positive molds for stuff like this because the end product has very fine layer lines, and i was thinking about how I would design my own lugs… I think you just gave me some ideas!

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.
