Welding

Mr Lefty · 01-17-2010, 04:04 PM

anyone do any welding on their bikes? like making racks for luggage?

I'm thinking of making my own racks for some panniers, and maybe a new tail rack that doesn't require me to remove my seat to remove it.

I wanna save money, but also be nice to design it the way I want/need.

so anyone do any welding?

Yeh what do you need/want?

I built a car and a bike, a few go carts and a bunch of other stuff.

Are you looking for a design? Of the actual work?

I built a plate holder for my bike and incorporated a quick removal bar for my tail bag so that I have a solid/non-plastic section to strap the bag onto. I'll take a photo in a few so you can get an idea of what I did.

just looking for someone to ask questions...

I wanna do the work myself, cause it'd be nice to not have to bug someone else to do any changes/fixes I need.

but yes I'd like to see your tail rack...

Thats the plate holder. All it is is a vertical pipe bolted to the subframe using existing bolt holes. That was welded to a horizontal pipe and the steel strip (plate mount). I have a small 2 foot aluminum bar that goes through the horizontal tube and is held in place with a pin and a cotterpin holding the pin in. I designed it so that all i have to do is pull the cotter pin out, th eretaining pin pulls out and the aluminum bar pulls out.

It's for this bag, there are 2 straps in the back that really don't have anywhere to strap on to, so the bag has a habit of inching forward.

Eventually I want to build a set of hard bags and a quick release rack to drop them off.

yeah I want to create racks for a set of pelican 1430 top loading cases... but the racks I see set them too far back IMO... I want them forward of the rear axle, so that the handling of the bike isn't altered as much.

how hard is it to learn to weld?

Any idiot can weld, just a matter of having the materials and tools. To weld WELL takes a LOT of practice. I've been welding on and off since I was 8. My welds are strong and will hold, but quite often (especially with a stick welder) they look like bird shit.

Not hard at all. Welding is one of those things that are incredibly easy on paper but is difficult in practice. The best advice that I can give you is to either buy a small, cheap welder and practice, take a class or borrow a welder...

I could explain the theory of welding but you really need to get the stinger in your hands and go for it! There are innumerable videos and books on the subject. You may even be able to get someone from the motor pool to help you out.

I could care less what they look like. just as long as they're strong.

I think the hobby shop on base will give me a place to practice

Buy this book, it can be found in any Home depot or Loews, then read it

This is what a good weld bead looks like

And a good diagram that I have taped to the side of my welder

If you want to learn, buy a cheap flux core wire fed welder, and practice. practice, practice.

I bought mine a few years ago, and my first project was a welding cart. built that and with the lessons I learned from the first build I built a 2nd one that wasnt so wobbly and warped. After that I just started to build stuff.

That's a great place to start.

First, just start making beads on a single piece of metal, to get the feel for it, and how it needs to flow to be smooth.
After you have that down, then you can move on to trying to make two pieces of metal stick together.
