Thanks - I have to say that shaping those caps and getting them properly oriented to one another wasn't simple or quick.

I agree. Can't wait to see what magic JB works on this....

Those lugs are spectacular. One day I'm gonna have to get me a Kirk.

Clear coat looks amazing!

I strongly believe that one can really judge the quality of work by looking at its edges. Making the great open spaces look good is simple - making the edges look good is where the time and effort is spent and shows the real skill of the craftsman. Lug lines are my edges and having them end up square and clean is the goal. This is even more important when the work is stainless and will not be covered in paint. This stainless Onesto needs its rear triangle added and will then get its final buffing.

Fillet brazing is one of those activities that demands real concentration while at the same time using muscle memory and letting it happen. Rather zen-like I know as those two things sound at odds...but while it’s happening it makes perfect sense. Picture the shape of the fillet in your mind and then let it happen. I’ve built thousands of fillet bikes over the last 30 years and the joy of standing back when the torch is turned off and seeing what happened is still very much there.

Beautiful...thanks for sharing the photo and your insights to the process.

Gorgeous work as always Dave, and a captivating description..

My eyes go to that tubular rim though, is that something you use for checking tolerances, or just a coincidence that its there in the picture?

That is an old wheel of mine that I've got set up with perfect dish so that I can double check alignment. It's GL 330 Mavic rim laced a Dura Ace hub. That wheel has been hanging next to the bench for decades now and has been slipped into most everything I've made for a very long time.

Dave- is this an Onesto frame? If so so are there any special concerns fillet brazing stainless as opposed to working with stainless
lugs?
Thanks

Awesome as always. I had a teacher once who use to say that the way to hold your mind during meditation (or brazing...) is like that of an archer poised to let fly. If the bow is too taught, you will break it. If it's too loose, nothing will happen. I always liked that analogy...

The basic procedure is very similar to laying brass fillets on steel but working with stainless and silver is fussier. One needs to jump through a few hoops to be sure you have a strong joint but done properly the tubes will fail before the joint....and the tubes are bizarrely strong.

And yes this is a fillet Onesto so it's all stainless and silver.

I like that too - thanks for sharing.
