Cracked Luggage Rack

I have the Krauser side bags on my '75 R90/6. The racks are chrome. The one on the right side has a crack in the weld that holds one part of it together. It is cracked all the way through for almost one half of it's circumference. So I figure to have this welded and wonder (since I don't do welding) do I look for MIG Welding or TIG Welding or just what do I ask for.

This should be a small job and I can take the racks off if need be but do I or should I remove the racks to weld them? Can it be repaired in place?

The metal inside the cracked area is rusted. Should I clean the rusted part down to bare metal before looking for a welder?

What should this cost me?

Take the rack(s) off and drop them off at the welder. It's thin tubing and he'll need to use his best weld-foo. Let him do the prep. On the cost, "if you have to ask, you can't afford it."

I'd look into getting your welder to add a strengthening plate
while he's at it

If you are going to rechrome, it would be much cheaper to buy a good used rack.

Well I don't think I will rechrome. I think this was broken many years ago in a 360* flip over. The bike has always been just so so. I don't have any bent parts and the bags were not cracked. The front end was slightly bent but I fixed most of that last year. Sub Frame might be slightly bent but if it is it matches the rest of the bike. I have the racks off right now. I'll look around for a welder. Bob's might even do it. Or know somebody who will.

Mig, tig, arc or braze. All will work.
Tig will be neatest straight up, Mig will clean up, arc if you have to, brazing will be strong enough.

All will destroy chrome in the immediate area.

Yeah, method doesn't really matter so much in this case. They'll probably use mig or tig though. Additionally you can have them grind the welds flush and blend them them with the surrounding material. If you don't plan on rechroming, you'll at least want to hit the welds with some paint to keep them from rusting.

Don't waste your time. Buy a new side rack for $35 off ebay and be happy. All of this we are saying to encourage you to take an interest in the things that make up the systems on your motorcycle.

You got me good.

Guess I'll look for used racks. I can still use this one. It is pretty solid when on the bike.

That was good pecos! I just read the other thread, and that gave me a good chuckle.

If they are like most all BMW tube saddle bag racks, welding them will not work because they are brazed. Gas, stick, MIG, TIG will make a mess of them. For some reason, nothing but sloppy crap welds can be had anywhere close to brazing. They need to be re-brazed. I braze gussets on them and use the back cross brace. They crack all the time without them.

Sometimes I am full of a lot of wordy BS. I used to write what is called "Copy". Advertizing for radio. I tend to speak in lines sometimes too.

I was an AM radio Disc Jockey when I was in High School. Some of the other older guys will remember how it used to be. It wasn't unusual in those days to work at a small time radio station when in High School. I also worked part time for AFRTS when I was over seas in the Army. And went back to radio after the Army. It's really a much longer story. I tell this story sometimes in some of the Inmates Threads like in the MNwilly Memorial Stay Sober Thread.

It's been over 41 years now since I was last On the Air. Some parts of such things are getting foggy and sometimes the memories are like it happened yesterday.

Sorry for all the digression. Now back to clutch repair.
