Brazing Setup for Bicycle Framebuilding | Torch Rig Overview

[@jimgourgoutis]

I bought a $45 Hoke jewerly torch, T grade hoses, $65 propane regulator from National, and use an oxygen concentrator and propane. Super-cheap way to get started.

[@jimgourgoutis]

ah, you mentioned oxy-cons. cool!

[@cobraframebuilding]

Very cool. Thanks for sharing!

[@frakafrocka]

this is an amazing video. thank you for making my brain bigger.

[@p_khale07]

Your videos are amazing , can you do a video on front dropout brazing(replacing old ones with new).

[@Nine_883]

Propane brazing torches have a big flame. Not easy to pull it down into a point for small stuff. It’s a whole different handle and everything. Harris Stay Silv black brazing flux works great for silver and bronze.

[@keithyoung7]

excellent vidio - thanks

[@arturom.escajeda1159]

Thanks for the video! What size tip are you using on the Victor torch? When I search "Victor J-28" I just get the handle, not the tip...

[@tractortherapy42]

Lots of good info - thanks!

[@jamesplantain-ox3ks]

Damn kid. Your awesome

[@tonyfoxxbuilds1920]

Not sure where you're at. But I was able to find larger tanks on fb market place and Craigslist.

[@frakafrocka]

Is it fair to say that some brazing is involved in all steel frame building? You need to braze the cable stops and bottle mounts correct? They cannot be welded? Thanks

[@squiresuzuki]

Not strictly. I mean, the "braze-ons" on titanium and aluminum frames are welded, and I don't see any reason you can't do the same with steel. But I would guess most prefer the aesthetics of brazed braze-ons. Also, with butted tubes, welding braze-ons on the thin .4-.6mm middle sections would be difficult.

[@musicwhiz711]

you ever tig braze any of these frames? A video on it would be rad!

[@cobraframebuilding]

I don't have any experience with TIG brazing. My, mostly uninformed opinion, is that it's probably only useful for a couple things on the bike. Maybe some of the braze-ons or lower stress joints like stay bridges. It might not be a bad way to go for water bottle bosses where you're welding a relatively thick part to the thin un-butted section of the tube. I may dabble with it someday, but probably not too soon.

My local welding shop can fill bbq sized bottles with propylene (map) gas pretty cheap.

[@7R1LL10N]

Is silver too weak for rack mounts?

[@Liljoozy]

Is it possible to add water bottle mounts to a frame without screwing into it? I mean like by melting the metal of the bottle holder onto the tube rather than drilling INTO the tube.

[@alexambro4998]

You can use studs instead of bosses

[@johnpalma7265]

Why do you have your work bench in front of the door?

[@journeyquest1]

My friend was a certified welding inspector and he had a 100 lb propane tank and rented the oxy tank.

[@obfuscated3090]

Leasing is usually a bad idea except for a business.

[@jimgourgoutis]

Are those the Smith kevlar hoses, or the ones from Tinman Tech?

[@cobraframebuilding]

I think they are smith, but I got them back in like 2010 so I don't remember for sure anymore.

[@Alistair_Spence]

Those are Smith. The TM ones are plain back rubber.

[@jimgourgoutis]

Alistair Spence Hi Alistair!

[@davidpayumo23]

I shopped around and found a place to that let me buy bigger tanks. But places like Praxair will only let me buy small tanks. So shop around.

[@mirkomaleni2769]

for a novice framebuilder wannabe this is the most expensive setup that you have there
