    you mean using silver instead of brass on the slotted dropouts where there's big gaps ??

    i cant really see what's going on

    ummmm, I don't get the "crazy" part. What's wrong with the photo sequence? It's very common to use silver to braze forks and the do's he's using are external socket types, so no big gaps to fill. I didn't look at all the photos, but judging from the look of the flux and the shorelines in the post braze shots, I'd say Mr. Wright knows his stuff.

    i worry mostly about chris's dropouts, as i'm not sure that they'll handle the rigors of frequent urban fixed riding. but then, ive never made a frame, so what do i know? hence, the question? is he crazy? i mean, yeah, he's crazy. but, is there evidence of crazed behaviour and consequences in these photos?

    Neither do I. They look exceptionally clean and well done.
    I'm not one for fawning over bicycles, but I do believe that our bikes communicate with us, and what this bike is saying is, "You're an idiot." BikeSnobNYC

    it's standard procedure to silver braze plug-in style ends, and the pics show one fork like this..
    but there's also pics of rear dropouts and another fork which are slotted style...
    it looks like he used silver here
    since silver loses much of it's strength when filling a gap bigger than (i don't remember.. something like .3mm ??) most builders use brass filler for these kinds of joints..
    maybe he used something different than 56% with better gap filling characteristics ??

    why doesn't somebody just ask him ?

    A good brazer (which this guy is) can fill a slotted dropout gap with 56% silver, but I'd bet he used 50n or some 45%, which would be much easier to fill the gap with and be a bit stronger. I used 50n on my first frame (slotted ends) and it's held up well to the "rigors of urban fixed riding".
    What I liked most about the pic sequence were how tight the fit for the tires was, maybe not the best thing for street riding, but damn, it looks cool!

    it would be a bad idea to use 56% here
    it doesn't matter if you can get it to fill
    it just won't be strong enough

    i can't really think of a good reason to not use brass here
    it's cheaper, and the higher temp will not matter in this area

    Did he use the material of those two flat spoonlike thingies to make the plates for the track ends? They may well be stainless steel for all I know.

    Someone started a thread about my build?

    I used 56% on the track ends. what a pain in the ass. 56 flows much better than 45 or 40 so filling those gaps was tough.

    For the fork (my fork, not zack's) I switched to 45%. That's what I plan on using for slotted style dropouts in the future. lumpier, and easier to fill gaps

    As far as strength issues... there are none. as long as the joint is brazed properly.

    The two spatulas were going to be cut-up and used for stainless faces, but my friend talked me out if it. I ended up ordering a sheet of stainless from mcmaster instead.

    Ceeway has some crazy arrowhead lugs I want to build with. I can't wait

    Pins/nails on round blades and external sockets?!? Why? They're not going to move out of track or change angle, are they?

    I like to braze from above my work. Gravity forces the silver to travel down the joint. Using a pin allows me to flip and turn the pieces however I want. If there were no pins, the metal would deform and throw the alignment off.

    Do you really think the socket is so slack to begin with and the heat will be so great, bearing in mind you're using silver, that the socket will deform and allow the blade to fall out of line in the socket? If the socket is a slack fit, just give it a few taps when cold with a pin hammer to tighten it up!

    HEAT forces the silver to travel! Stand the blade/socket assembly in a vise, heat the socket first and the blade next, go in on one side with the silver and draw it round with the flame. That's it. Do the other blade and another half dozen of them in the time it takes you to drill, pin, braze, cut off the pin, file off remainder of the pin, etc.

    Unless, of course, you like making more work for yourself.....

    Thanks Neil.

    It's just my preference. There's more than one way to join the pieces together.

    Agreed.
    Hard way and easy way.
    I know what one I'd choose!

    ok hold up
    cause now that mr. walker has weighed in i am getting truly confused...
    here is a pic of a slotted dropout brazed with something silvery (i had no idea what mr. wright actually used, like i said before, but later in the thread he tells us it was 56)

    but everything i have learned tells me that 56% is not a good idea when brazing fork ends in slotted stays

    so what's what ?
