| Cleaning up brazed joints
Ok, so I've built dozens and dozens of frames, bumpers, etc. and have always used my own method for cleaning up brazed joints. Then I got to thinking, heck other people are cleaning their joints as well, maybe I'm missing something that makes it even easier to do. I'm always open to learning new tricks Anyways, here's my method for cleaning up joints: 1. Scrub joints with steel wool under hot water to remove residual flux. 2. Sandblast at around 300psi to remove flux from hard to reach areas. 3. Hit the joints with Dremel sanding drum to take out any rough spots. 4. Smooth joints with Dremel flapwheel. 5. Get any hard to reach areas with hand sanding/filing as necessary. Takes a while, but gets good results. Other opinions/methods? |

I sandblast (80psi max) and paint. I try not to leave any boogers when I'm brazing so the clean up is alot easier. Heres some joints before I cleaned them. |

when i braze, i try to get just enough on it to bond the pieces. not trying to build it up more then i have to. easier said then done, its very hard to clean up blobs even more in tight areas. i just use an assortment of files to clean up my work.but usually as i building and have a messy area ill grind it down on the bench grinder before i forge on. i use coated brakeline. so when im cleaning it up after its all brazed together i clean up the chassis til it is all shiny. my way is very slow. takes probably about a good day to build my chassis's and a good couple days on clean up even with minimal clean up. the better prepped the better it looks after paint. i will usually wire wheel it. then the tight areas that the wire wheel didnt get i do with the files. every one has their own ways. but it mostly comes down to what you have to work with. i enjoy brazing my own chassis's, but it does involve alot of work.

I genrally just use the dremel with a grinding disk, and a few small files I have sitting around. Doesnt get the joints perfectly smooth, but then again I'm building comp scalers not show rigs. If I had acces to a sandblaster I'd try it, but not worth the expense to me to buy the equipment just for cleaning up my metal work.

In addition to what you guys have listed, I use: Emery cloth torn into narrow strips Small size wire brushes Buffing wheel To prep coated brake line before brazing, I sometimes put it into my drill, spin it while working the end with emery cloth. |
