So I'm thinking about brazing a fork...

[Jamie Hascall]

Dazza, Thanks for such a great description of the sequence. I've just been preparing the crown for my first fork and that helped a lot in how to understand the process.

When you talk about pinning the crown to the steerer and then fluxing, do you apply a layer of flux to the mating surfaces before assembly and pinning, or will the capillary action and heat draw the flux through the joint sufficiently? Also, did I understand the later post that you seal the fork blade vent holes after soaking out is done? Do you dry out the interior first with a light heating? It all makes sense but I'm just wanting to confirm a few thoughts.

Thanks again,
Jamie

What I do is
Clean all surfaces, { no touching with fingers}
check the fits and ease the fit if required
drill for pin
take apart
flux the surfaces
reassemble with the pin {I use 2.00 mild steel bullet head nails and taper them on my bench mounted belt sander and I ip the protruding pin off with small cutters}
Apply more flux around the joints outsides
then
within 30 mins
cook it up

In all my fork blades I keep a vent hole in the dropout {the upper one is filled/pinned after trhe soak in the pickle tank and drying out}
and the seat stays are vented through the seat lug
and at the dropout
I squirt Tectyl or such like inside SS and FS {and all other tubes}

Later I want a fork crown like the LC32 but no hole underneath {I plug them in he LS32} so flushing is easy
and spraying anti rust is easy
and one less step to worry about
and a crown that suits my build desires {one day}

any questions?

Sweeet! Thanks for the great show and tell.
