I'm sorry this isn't Buell related so it'll probably get deleted, but has anyone had experience with laser welding? My horn mount broke somehow and I'm too impatient to wait for a new one to ship so I have to get it welded, again. Doing some research I've gathered laser welds are decently stronger than conventional welds so maybe my bracket won't break again if it has a stronger weld. Or should I just ditch the horn? | ||

Welds are generally stronger than the parent material if done correctly. did the weld itself actually break or was it the metal directly next to it? | ||
| Theironmaiden22 |
It was the weld itself, thats why I was thinking of getting it laser welded since they're stronger supposedly, probably costly as all hell though. | ||
| Nik |
Then the weld wasn't done right. Why is the horn bracket breaking in the first place? | ||

Laser welding is VERY expensive. Plus...even if you could come up with the money, most good laser outfits are very busy. As others have noted, proper TIG or even MIG, should take care of it. I've got MIG welds in some pretty high vibration environments with no breakage. Mike | ||

Just Mig it and forget it...hmmmm sounds like a commercial.....wait!!! there's more!!! Seriously...just weld it...and maybe look at some vibration damping material...I'll bet a harmonic vibration killed the weld.. | ||

We laser weld in our dental lab all the bloody time, if a bridge doesn't fit then we can hit it with a laser to correct it's fit as well as welding 2 halves of a bridge together, and partial frames too. We can weld anything from a chrome-cobalt alloy, nickel-chrome, palladium, gold alloys with up to 77%AU, we've tried welding 86% and 99%AU alloys but it splatters too bad. I doubt you could weld 2 pieces of aluminum with either nickel-chrome or chrome-cobalt, it didn't work on my glasses and they're aluminum so I used gold which held but that would be a costly horn mount if it were to be welded with gold. I would try and weld it for ya for free but shipping time to here in the UK would be longer than it would be to just order a new bracket. www.orotig.com These chaps make all sorts of laser welding stuff, mostly dental though. | ||

Actually, if there is anyway to size the bracket down a bit then I could just cast one out of a dental alloy. They've great thermal shock properties, like that matters with a horn bracket, and aren't brittle. We've had to fix older peoples partials cause they've stepped on them, don't ask how, and not once have I seen the metal actually break, nor the any of our laser welds. | ||

Is this mounting bracket for the electric horn under the flyscreen? | ||
| Theironmaiden22 |
Yes, the L shaped thing thats screwed to the black round thing (horn). And no, I'd just as soon 'jimmy a jenny' as you brits say and use some might putty until my new one arrives. I work in a dental lab too, in the metal department, so I know for a fact ni-cr or cr-co will not weld to steel, the brackets not aluminum or atleast I think. | ||

Why not take some flat metal stock, drill it and bend it? Isn't that pretty much all the bracket is? If it has supply and ground you could just as easily make a plastic bracket or run a ground wire up to the mounting bolt if it only has a single wire (and returns through the bracket). | ||

That's exactly what I did this morning at work out of an old partial frame, I used concentrated hydroflouric acid to eat off the acrylic then cut the tooth anchors off and cut it hot dog ways and bent it. Looks pretty damn good if I say so, I have yet to put it on the bike being as I'm on my lunch hour, if it works I'll take a pic of it. | ||

or you could just take it off and throw it away... but thats just me... | ||
| Theironmaiden22 |
I would take it off and toss it, but where I live, way too many people drive with their heads up their asses, or drive like old people f*ck, so a horn is a necessity and fingers don't always work when the person isn't looking in his/her rear view mirror. | ||

 Or....just make a new one.... | ||
| Greg_e |
It's a flat piece of stock with two holes drilled? Would have taken all of two seconds for me to decide to make a new one. if it had a bend in it it would have taken a little longer. Looks like it has a counter sunk bolt on the one end. | ||
| Theironmaiden22 |
That countersunk hole won't jeopardize the brackets integrity will it? It looks as if the old brackets broke right where the new one has its countersunk hole. I couldn't take one of those new ones off your hands for the right price could I? | ||

>>That countersunk hole won't jeopardize the brackets integrity will it?<< Could cause serious injury or death!!!!  (standard HD warning) | ||
| Greg_e |
It should be easy enough to make with a hand drill and hack saw. Even nicer if you have the correct size counter sink tool but I don't know what the angle is for this fastener since I've never even taken the front plastic off my machine. I would guess 80 degrees. What are the dimensions and hole sizes? |
