How do I attach 2 pieces of metal together without a welder and still be structurally sound? Answered

For me, all my friends, when they do such alterations, they only weld

Welding is probably the best way to assemble a bike. It could be dangerous to glue a bike together because glue does not penetrate the metal like a weld would. It is far better to weld or braze metal or use bamboo than to try and glue a frame together, its simply not strong. Once you got a welder you wont be as dependent on buying expensive fasteners and hardware, you can make your own

one simple word, duck tape

Hi. How would I attach 2 pieces of metal together without using anything but the pieces themselves and be able to take the pieces apart as well? Can I make finer/box joints or jigs or some sort of joinery method? Any suggestions please. Thanks so much

get 2 screws and matching nuts , drill 2 holes and pu the nuts on then 4 extra support maybe duct tape orwell idk thats my answer :)

By the time you buy enough epoxy, rivets, and bolts, you could've already bought a cheap stick welder and some rods.

Brazing or soldering... It's like welding but much cheaper. Or just buy a welder... once you start... you will never stop.

tube and sleeve, if the part you are trying to join is hollow you could put a tube or bar stock into it and secure it with a drilled hole and bolt, or even jb weld. the tube or bar stock would be the structural component.

Bolts or rivets. Get an engineering manual (Machinery's Guide, for example) in order to do the calculations you will need to be safe.

Try some QUIKSTEEL Epoxy. It's like a putty, you cut off what you need, and you kneed it with your hands. it doesn't take long for it to set, but holds just as good as a weld does. You can even use it underwater. It's pretty good stuff. You can most likely find it at a hardware store, or possibly even wal-mart.

. A lot of epoxies will be too brittle for use on a bike. Most glues will not be strong enough (although I have zero experience with Gorilla Glue). . Binary Boy's bolts (or screws) and clamps should work well for proof-of-concept but probably won't hold up to hard use. . klee27x's brazing idea should work best but if you don't have access to a welder, you probably can't get your hands on a good torch.

bolts and clamps

try the JB weld. works for me ussually.

Google "brazing, silver soldering, silver brazing."
