Low rider Braze-on question/ first time brazing
I recently picked up a Schwinn Passage frame off CL. It's a touring frame with most of the expected braze-ons. So that's great, but one of the rear rack braze-ons was busted off, and the fork doesn't have any low-rider mounts. I've decided to do the work myself with the assistance of my boss who has some brazing experience.
First off- the lowrider mounts.
I visited the shop of Matt Assenmacher, by recommendation of my boss, in Swartz Creek, Michigan hoping to pick up some braze bits. He's a frame builder who has built bikes that have won national championships. Here's a blurb about him and some of his frames.
It was quite the experience seeing some of the tubing, nervex lugs, cinelli fork crowns, and such when they weren't built into a frame.
Anyway, I picked up some through lowrider braze-ons, a hourglass rear rack braze on, and a NOS Blackburn Custom Lowrider Rack.
The through low-rider braze ons look like this:
and here's an image for installation:
My question for you all is this
when I get everything drilled and the braze-on in place, how do I go about brazing it without getting brass on the threads? It appears that the lip goes on the outside of the fork blade, do I braze both sides? How?
Rear rack braze
- this was semi successful. Due to my lack of experience, I clamped the rack boss to tightly. When the heat was applied, the combination of pressure and head smushed it and ovalized the hole; enough that a bolt wont thread through. If I can tap this out, all will be well.
