Braze-ons: What You Need to Know | Bicycle Framebuilding

- Brake mounts, cable guides, cable stops, rack mounts-these are all different kinds of braze-ons. Although some bicycle framebuilders design and fabricate their own braze-ons, it's most common to buy them from suppliers (see a list below) and then braze or weld them right onto your frames. In this video I just give a practical overview of different kinds of braze-ons, what to look for, and what options are available for how you handle this part of the bicycle as a custom framebuilder.
Here are my braze-on clamps, available in a 3-pack or individually: cobraframes.net/store/braze-o...

Nice instructive videos, I'm watching them all. Here is an idea for a new topic : "the different road bike rim brake types" and where to places the brake bosses depanding on the wheel size (700c ,650b). Thanks.
I silver solder copper at work and the flame I use on the oxy is very different to what bike builders use , it wigs me out !
I think that mustache is a braze on...kidding, love your videos. Learning a lot.
Excellent teacher. Thanks
This is a great video. Thanks for posting.
Interesting topic, thanks
Very informative. Thanks
No prob, Bob!
I was looking for wiring guides on my motorcycle frame build, came up with using braze-ons when routing new cables on my Surly Troll. Used about 20 of them on my old Harley dragbike build.
I don't know much about motorcycle frames, but if they don't have brazed on cable guides, I bet it would be a nice addition in some cases!
I noticed this post is a little old but I've been trying to find out what those bars that go across the seat stays are those little bars besides holding a caliper break or some other kind of break what are they used for what is their purpose.
You have good energy and a good vibe and if we met in person I'd want to be friends
To save money are bolt-on straps just as good as braze-ons? If I have a customizer mount Surly 2.0 front and Surly rear rack going to be okay? I hope to test myself on a 1,500 mile journey, then if I do well I'll leave my comfort zone and go around the world and take years to do it. I'm 69 yrs young and need to test myself. I don't own a car and do everything on my old Diamondback from 1998 with a Cro-Mo 4130 rigid frame. About how much would I save with clamp-ons as opposed to braze-ons? Thanks for a great video!
Hi. Do you think I can use a MIG/flux core for the cable stoppers? Just a couple, not planning in building a whole bike...
I'd like to know as well
Where’s a good place online to buy the different types of Gides
So.....I like your channel
but want to say, after 40 years of on again, off again frame building.... (1st
frame in high school at 16 years old in 1977), I noticed you and other frame
builders want to use a 'carbonizing', wide, NOT focused flame while brazing. My experience has been, and even today as I
brazed on a few water bottle mounts, that a small, low pressure, concentrated flame allows precise
and controlled manipulation of both silver and bronze. It is MUCH easier to control the heat and
focus it into the area of higher mass, i.e., the tube vs. the braze on, which
is easily overheated. Orange is not your
friend, and a dull red should be more than sufficient for silver, with dull orange
being the top temp for bronze. That
said, with plenty of white flux, a low temp focused flame, it is a simple
matter to control the flow and pull the silver in and through the joint with a
beautiful silver line around the joint. The
tube/joint should have very little black, carbonated, overheated, burned
evidence around it and should be kind of clean with a glass like flux residue
to be sand blasted off… (my favorite method).
Again, like your channel and keep it up…. great info for anyone
interested in machining/frame building.
You just wrote what i was thinking.👍😃👍
Admittedly my brazing is super rusty. I haven’t used the o/a torch much in years. The footage was pulled from another video where the point was demonstrating my braze clamps in use, not teaching brazing technique. I appreciate your critique and I’m sure you know what works best for you. For these I just adjusted the flame to slightly carburizing like I was taught to in the framebuilding class I took with Doug Fattic, and yes I might have had better control with a lower flame.
@@cobraframebuildingYeah, and as an old crusty amateur, I am only trying to offer good suggestions. What I see on you tube for some reason are all these 'carbonizing' or ‘carburizing’ flames. I will admit, after watching some of these vids, I tried a wide flame like that on the current frame I’m building and it was nearly disastrous, overheating and very little control. I did manage to salvage the frame but I needed to reflux and CARFULLY reheat and move the silver around with a concentrated flame……. Old school Reynolds 531 and Columbus SL and SP combo tubes…. Fairly forgiving but still….Anyway, love you enthusiasm and your channel and if I can be of assistance, let me know.
Can Romex Wire be strong enough to use as a brazing rod? To reweld the top of the frame that was cut off and repositioned?
I would assume not. Proper welding filler materials are dirt cheap. Don’t skimp on filler rod.
@@cobraframebuilding I got the rods 4 for 5 dollars it's bronze with flux coating. I hope my ts8000 propane torch will braze it.. 1600 degrees..
Do you know of any place i can find internal cable guide braze-ons that ships to europe for like not 100+ euros
Sir how to get brake braze one ?
Can you send me?
4 pieces?
Kindly!
He was very clear where you can buy these braze ons, Also left a list of companies who sell the products. We live in the computer age. Go for it.
