Alright, I want to put on a Reeder style handle on my uni, and I was wondering, will it hold if I brazed on the handle to the brake mount post. (see artist rendition below) I will be making the handle out of an old handle bar, so a bike grip can fit on. so please, give your thoughts and ideas on it.
I’m with skrobo. But instead of welding it to the brake mount, I’d make it like the JC coker handle (well, at least I think that’s what it is) and weld it to a mtb stem, or something similar. That way you can change the height and angle (if you should decide to).
If you weld thin tubes (std. 7/8" or 22.2mm is usually pretty thin wall stuff), then insert an aluminum plug about 1" long into the area where the 2 tubes are to be welded together. This plug will likely be about 0.8" diameter, or whatever fits inside without slop.
That way if you blow through the thin wall of the tubes with your welding torch, you’ll still have something to weld to and can salvage the piece. Plus this makes the joint alot stronger.
If it weren’t aluminum, brazing would be the way to go… it requires less heat but yields sufficient strength for the application. Most custom bike frames are brazed together. A good braze looks no different than a good weld. What makes you the expert, here, huh?
