I bumped into the videos when trying to figure out something and found them helpful

For work i repair SS mixers







For a hobby i build some fairly nice bicycles

howdy neighbor!
nice pics. i for one like to see how the other guy's are holding it down! those mixers aren't bicycle powered are they??

[jwmacawful]

have you ever built a recumbent type bike??

For racing i have done some tandems



For fun we built a good bit of junkyard wars rules triples and tandems with one rule you had to find everything from the garbage

[jwmacawful]

what are the bike frames made of and what process are you using to weld them?

Welcome to the forum.

[tommays56]

The tandems are made from a mix of .035 wall chrome moly tubing and tandem specific oval tubes as weight is not as much of factor





All my road frames are made from Columbus Nivacrom EL ( extra light ) and the material is sold in a complete set to build one frame

The EL tubes are triple butted with .027 ends and most of the tube is .015 wall for light weight and it is about twice the strength of chrome moly BUT it is really easy to screw it up

The first time you pick up a piece of material it is shocking how light it is compared to the same thing in .035

When they were building the Concord they developed a special new steel for landing gear parts ( Nivacrom) and Columbus ending up with the bicycle end of it


I build everything with a oye acetylene torch and a thin flux free bronze brazing rod as you need to flux before you heat

I use a torch because i like the look of fillet brazing and i am good at it as the metal is so thin

All of my TIG work is on really thick material so it is hard for me to dail back to .027 wall

thanks for the 411. i do a lot of biking and i often thought about building a bike. it was good to see someone who actually does make them.
