OK, so it’s been a while. I’ve been trying to get the Dart rewired and have been putting in lots of hours at work, so I’ve been a bit distracted as of late. I got the wishbone going for Brent’s cross bike, it’s soaking in the sink as I type.
I set up one side at a time, letting gravity help me keep things in place.
I warm everything up real good and give the whole joint a tinning pass. That helps keep the tubes from pulling as the brass cools. (metal expands as it heats up, and shrinks as it cools, so you put it on hot and the shrinkage can pull it out of alignment as it cools) Then I give it another coat of flux and lay down the fillets.
There you have it. A little heavier than a standard pair of seatstays, but much cooler looking imo. The tops of the stays will get a radius filed out of them, and then I’ll cap them off. I drilled the holes for the rack mounts on each side of the monostay, and dropped it in the sink to soak the flux off.
