Braze Puns

hey guys, i have a custom fork that got 3 holes on each side plus a fender mount at the bottom.

i want to use tubus duo rack and the distance is too long for that rack, and i need to add additional braze on under those 3 that exists, inside braze and outside braze that will be parallel to each other.

now, it will be dangerous to add two more? i aint going to use the upper 3 braze ons, maybe for a small bottle, but not something heavy.

the stress will be on the lower ones that i want to add and the bottom fender braze on.

im attaching a photo so you can see the type of braze, and approximately where the holes needs to be. its a hole that he weld a nipple into it, i guess, so the stress is on the nipple and not on the fork?

let me know your thoughts, cheers.

I’m looking into getting a new bikepacking rig that will also serve as the roadiest bike in my fleet. I have a Karate Monkey for primarily trail routes, but want something that is a bit more capable of long distance road riding (with some chunks of trail riding thrown in). Cross-ish geometry. Specifics that are important to me:

-Triple braze ons on the fork and frame -Disc brakes -Thru axles -Tubeless tires, with clearance for something up to about 2”

What suggestions y’all got? Looking for something I can potentially get used for under $2,000 (I know the market is tough right now).

Hello everyone, I am new to the residential HVAC industry, but have about 10 years experience with industrial chillers. I want to know your opinions about brazing vs using some of the newer products such as, Zoom Lock crimping or slide on fittings. I ask this because I have seen very poor brazing jobs across the units I've worked on and looking at it from a future business owner's point of view, it's difficult to ensure uniformity of practices across different years of experience. Have you seen a high fail rate or any at all on such methods?

A co worker from another property showed me how he uses MAPP gas with Bernzomatic ts8000 tip to braze all his copper lines. It worked like a charm for him and I am going buy one just so I dont have to carry the damn oxygen and acetylene tanks on top of two story roofs anymore. I dont know maybe we are just lazy maintenance guys but it sure did look alot easier to me, and it worked great. Anyone else use this method?

I ride an old steel-frame road bike which doesn't have any mounts for a bottle cage. It also doesn't have the eyelet things I see near the top of the seat stays on other bikes that can be used as the top attachment for a rack (it does have mount holes at the rear fork though for the lower attachments).

I could probably make do with a clamp-on bottle cage and P clamps for my bike rack, but I was wondering whether there's any sort of bike shop or frame builder in the area who could braze or weld on eyelets for a more permanent and sturdy solution. Or maybe a general welder would be able to do it? I tried a hose clamp-type approach for the bottle cage a while back and found it slipping after a while.

Over the last 3 days I have broken 5 braze ons! What is going on? The frame is steel and they are the factory bolts. 2 by tightening and 3 buy lightly bumping into them. Could it be the bolts are low quality? Over tightening? Just the nature of the beast. Trying to get geared up for the baja divide and at this rate I won't have any left before the trip even starts. Any tips?

I reached out to Salsa regarding this and they told me the bikes do not include these bolts. Was wondering if there are others out there that experienced the same thing.

Please see the Steel Nut:

Can I braze this to aluminum sheet, using aluminum brazing rods, and get a strong (and even somewhat attractive) result by just filling each of those holes in the nut? Will the aluminum plate surrounding the steel have any evidence of being heated, any ugliness?

I assume the surface area of so many holes will exponentially help strength

Thanks

i have a steel fork and tubus duo front rack.

i need to add lower braze ons as the distance from the eyelet to the alreay brazed braze on are to high, and i need to add inner brazed on as well.

should i consider something? or its a safe project?

Can I silicone bronze braze a chrome part or do I need to grind the chrome off first?

Curious to know if there are any dangers, as with galvinized, and also if the bronze will take to the chrome.

Thanks
