The Chopper Compendium

Iam hoping to master this method I like it had a go recently and although my set up is pretty basic just fluxed rods and a hobby sized torch and a small set of different sized nozzels I really had some fun, enjoyed it much more than using the mig, I understand you can get silicon bronze mig wire would like to give it a go... I guess you might call it old school but in the hands of the professional the end results are just amazing..

Anyway some pictures of proper brazing done By Brian of

Nice work.

NB: It's probably just my twisted mind, but the first thing I thought when I saw the picture of the front of the headtube was all that'd need to be the back of a naked woman would be a head (or back of a head, and spray of half a dozen lines of brass there would give you a blonde head ;^)

real nice

Looks very difficult. Lots of nooks and crannies. Quality work.

Those are great photos, great skill and workmanship.

The term "Brazing" is not really accurate.
Brazing is the term used to describe a filler that flows by capillary action into a very close fitting joint.

The frames above look like he have been "Braze Welded" or "Bronze Welded". These terms apply to a filler wire that joins the parts without flowing by capillary action. A few decades ago it was called Bronze Welding, the modern term is Braze Welding.
I prefer to call it Bronze Welding (I'm very old school) but this is not an accurate term as the fillers are Brass (i.e. copper and zinc with other alloying elements like silicon, nickel, silver, etc). Bronze is copper and tin with other alloying elements.

I have used Braze Welding for many years to repair and modify steel tubular bike frames, mainly dirt bikes.
I use "Castolin 16 / XFC / MF" filler wire and a light weight oxy-acetylene welding rig / torch.
Castolin 16 is rated as "AWS A5.8 RB CuZn-D" under the American Welding Society system.
Castolin 16 is alloyed with 1% silver and nickel. It fits the definition of both a brazing filler and a braze / bronzing filler as it will flow by capillary action but by reducing the heat input (temperature) it can be built up into fillets.
It has a tensile strength of 700 - 800 MPa (about 100,000psi minimum).
It is reasonably easy to use and with some practice very good results can be obtained.

Met a guy in Las Vegas who used brazing to build a frame. He did a copy of a vintage BMW frame, using smaller diameter tubing
for the primary members, which were inserted into a larger tube at the junctions and then brazed at the interface of the different tubes.

His bike looked really sweet.

Anyone thinking of doing some gas work might find the chart useful. Same chart Word and Exel.

@Maxthegardener that is pornowelding! Wooooow!
