Soooo...that Alumiweld stuff can be welded with MAPP gas? Sounds almost like brazing actually? What kind of stuff is it? (I mean, oviously there's aluminum in there, but I've never got around to trying it so I don't really know it.) How do you use it and what metals can you use it on? Can you use it to make gas tanks?
Try resting the tank on a wet towel. Or drape a wet towel over the areas that are already brazed. I have not tried that but it might work.
I was thinking along the same lines and am considering using frozen wet paper towels or a rag to place directly against the part already soldered/welded. Paramount is cleaning the area to be joined with a stainless steel brush and not regular steel wool or a steel brush which contaminates the aluminum somehow. Within a day or two I'll be making up a rear drop stand for my Elgin out of aluminum channel. Or at least trying to... The little experience I have with these rods (used about half of one so far), it seems like the propane torch I have works fine (Bernzomatic with a pencil tip).
A trampoline spring might work. The coils are so compressed against each other that there'd be little vibration from the road. Any looser a spring, and the reflection of the car behind you will be jumping around like a Chinese acrobat.bardico. thjis may sound a bit dorky but if you get a spring offa an old trampolineand weld your mirror to that you can nock it on stuff and ittil sprung back in place
im going to sleep now before i confuse myself anymore
harbor freight has something called "hylo-cool" that i picked up for welding in new floorboards on my caddi' that i think would do the job for yah!
I've used those rods many times in the past and it's GREAT stuff. Can be found in most hardware stores. If I were to guess what they're made of I'd guess zinc.
