Brazing my nuts to a tuber.....

[mrpink]

Thought I would throw together a quick How-2 (or at least How I do it) on brazing nuts to a tuber for attaching side panels, skid plates, etc etc.

First.... materials.

Braze and Flux:


Torch:


At least a 10" piece of all thread and nut:


Other materials used.
Marker
Pliers
Dremel maybe



Step One: Mark where you need the nut located. (I use a sharpie marker, a scratch awl would work better through later steps)




Step Two: Apply a small amount of flux to the tube.



Step Three: Apply a small mount of braze to the tube




Step Four: Thread the nut onto the end of the all thread... just enough to hold it securely. Make sure the all thread is long enough; you will find out why in a few steps.



Step Five: Apply a small amount of flux to the nut. make sure you only get the flux on the outside of the nut that will be in contact with the tube.



Step Six: Hold the nut up against the tube and apply heat evenly... the nut will heat up alot faster so concentrate your flame more on the tube- this step takes a little practice and dexterity. You will see the braze liquify and attach to the nut after about 5-7 seconds. Be sure to hold the nut right where you want it. (Btw, this whole time you are holding the all thread that is holding the nut.) Once it has brazed, hold it there untill the braze cools (about another 5-7 seconds, you will see it get dull again.)



Step Seven: Unthread the all thread. Use the pliers to starighen if needed (let the metal cool down first) Done.




Now... most nuts are galvanized. And you are supposed to not breathe in the fumes when they burn. I dealing with a small nut such as 4/40 or 6/32 I simply put a small fan on to blow the fumes away. You could wear a mask, or soak the nuts in muriatic acid for a few minutes to remove the coating. Fan works for me.

I have found that stainless all thread works alot better than galvanized. If you can find some, pick it up.

Don't burn yourself, don't set your house on fire, don't do drugs... if you feel as if this is over your head, get someone to help you or pay someone to do it. You've been warned.

Now go braze your nuts little kiddies.

Thats the same way I do it. Works mint. As for the Galv. coating drink milk after breathing or burning it, it's supposed to help from getting galv. poisoning.

I weld galvanized at work and the milk trick really works. The best thing with the galvanized would be to just move outside on a porch or carport in the fresh air and then there would be nothing to worry about.

Cool, I heard milkshake (not milk) to help with welding, brazing fumes etc.

So you're advocating paying someone to play with your nuts?

Good howto, I usually have my wife hold my nut(s) with pliers and gloves, then braze them up. I'll have to try this way next time.

Yeah, I fully expect that will show up in someone's sig soon.

Excellent tip I use the same method. But Ive never applied brazing rod to the tube prior to attaching. I'll have to give that a shot.
Thanks

That's exactly how I do it as well.

We need a sticky with all these tuber building tricks. I am getting old and forget stuff real quick.

you asked for it

[Mac10]

I can't tell you how many times I tried to weld nuts to my tuber and after failing too many times turned to zip ties.

now after seeing this I will have to go out and try again.( once my liver heals from vegas this weekend)

Thanks MrPink, I thought this would be a good wat to attach the nuts but didn't try it yet. Seeing the great photos took all my doughts away. Time to fire up the torch in confidence!
