I've been looking to do a retro mod myself for a while, that looks amazing.

How did you braze? What tools?

Genius work. Really impressed. And very inspiring.

Thanks guys, I've been putting a lot of thought into this!

I only used basic tools,

Hacksaw (removing the canti bosses, rough cutting the brace tube)
Files (10" flat second cut, 6" and 8" round second cut)
Shop roll emery cloth (1.5" wide, 80 and 120 grit)
Mole grips (to weigh the cable stops down and help remove them when heating up the old brazed joints)
Jubilee clip and old arc welding rod (to act as a fixture to hold hose guides in place)

Oxygen and acetylene bottles with torch (I understand that you can use MAPP gas torches - DIY stores / builders merchants but I haven't tried this, I think it will depend on what melting point the brazing rod you have are and what the melting point of the braze used from the factory is if you're removing braze-on with heat).

Brazing rods
Silver solder (I used this in the bottle cage bosses in the middle of the top tube as it has a lower melting point, so the really thin bit of the tube doesn't need to get too hot).
Flux

Then there was some practice brazing with similar thickness materials, before going near the frame!

Nice job, you must be really proud of that. Bet it's a keeper for life now.

Beautiful build, always nice to see something a little bit different. Love the detail, especially the 'HOT ROD' decal. Only die hard Kona and Retro bike lovers would get that play on words - love it! :D
