Help with brazing cable housing stops
Specifically what type of flux and filler do I need for brazing aluminum cable housing stops to a Reynold 520 Cromoly frame?
Also I am modifying a rear derailleur hanger. I am adding a small bar to the hanger to keep it properly aligned. The hanger is aluminum. Should I also use aluminum for the bar or a different metal? Then what flux and filler for the hanger?
Thanks

There is a supplier sticky at the top of this forum.
I would consider bike fab supply or framebuildersupply

I have a good stash of various braze on bits including cable stops in a few configurations. Feel free to PM me if I can help you out. Andy

You can even weld aluminium to steel but only by using high explosives. Probably not a good idea to attempt this in your garage.

It makes no sense to do this with aluminum when steel parts are easily available. Joining dissimilar metals is always going to be an experiment best left to people that really need to do it.

Just buy some steel braze ons and some 50 - 56% silver solder and the appropriate flux. I would stick with ordering the stops from Bikefabsupply or Framebuilders Supply, because NOVA will kill you on shipping for small parts.

Is that still true about Nova? In the past they would send a different way if you called, I did that once.

With Nova under new ownership you may want to call them and see if that is still the case.

As a test, I put 10 cable stops in my cart and the shipping calculator shows $16.12 to ship to NJ. I don't know if they would put them in a padded mailer and send them USPS if you call, but I have an irrational aversion to calling places to ask about stuff like that. I know Andrew at Bikefabsupply will only charge me the actual cost of shipping and refund any difference from the online shipping calculator.

I don't like it either, but I think I did it before BFS and FS showed up. Henry James was the same way. Bad postage estimators.
Of course, now companies are a bit worried about using priority mail, but my experience with Paragon and priority mail has been good.

And what was the refund amount? Asking because I feel that some small amounts of doing business are not worth the efforts to save more on sometimes. Andy

You gotta pay someone to put the small order in a box and ship it, so I can understand why there is a floor at some companies. Don't really see it as dishonesty or honesty really

[QUOTE=guy153;21951987]I think you can braze aluminium to steel using something something like an aluminium bronze rod.
You can even weld aluminium to steel but only by using high explosives. Probably not a good idea to attempt this in your garage.
You can, but not for the home welder. You will need to use a bimetallic transition insert or coat the steel prior to welding / brazing.
