Hey All,

So I found out the hard way that Paragons sliders are a mofo to braze, especially when you are using all the wrong stuff. Turns out that Harris white flux isn't good (at all) for ss and that I should have been using the black flux. I also found out that although 56% is great for brazing ss it's not really the best for bridging the gaps for this type of drop. It kept pouring out the the slots I cut for the drops.

Anyway, I read this post from Dave B (thanks, this was very helpful) http://forums.mtbr.com/showthread.php?t=537369
I'm gonna try 45% silver and black flux. Other than cleaning the tubes really well is there anything else I should do to make this less painful?

I should have read up a lot more on brazing stainless before jumping in I would have saved myself a lot of time and cleanup on that chainstay. I wasted an once of 56% silver trying to braze a single chainstay.

Thanks in advance. --Mark

I found brazing my SS James drops tricky too. Of course by the time I did the 4th plug I had it down pretty good. I ended up laying the heat to the 1st one a second time because I wasn't happy with the amount of sweating on it. I used HJ's blue flux and it seemed to work fine. Definitely over 30 hours on the frame and nothing has broken. I even crashed last ride. Everything's normal then :-0

Sounds like you are on your way, I am glad I could be of some use.

Blatant plug approaching.......

Wade and I sell a brazing filler just for this purpose and also a corresponding flux. It is called Fillet pro silver and Stainless light flux. It has been designed to do exactly what you are working on now.

If I told you what it was I would have to kill you, but suffice to say it is a lot cooler than plain ol' 45 and harris black:D

Dru, The Gasflux stuff that is blue is typically reserved for bronze brazing. I am glad it worked for you but if it is what I think it is, it's best use is not for silver brazing to stainless.

Thanks Dave, I didn't know that. Maybe I'll put your and Wade's shameless plug to use on my road frame (still in the planning stages)

Fillet Pro and Stainless Light are awesome. Makes the impossible possible:

I concur. Love the way it flows. Love the way it cleans up even more.

Joel- I got to see that bike in Richmond. Stellar work!

Thanks all for the replies.

I had already purchased the black flux and 45% silver from my local welding supply and since the smallest amount of fillet pro I can get only comes in 5oz coil I'll hold off and use what I have now, but I will certainly keep it in mind for my next build.

I also had the chance to see Joel's bike in Richmond, awesome!

Thanks again for the help. --Mark
