I binned my old horn, bu now need to know how much it weighed. i want to locate the shendengen R/R in the horns original location, and need the weight to determine how stout the bracket needs to be....

anyone?
 
You want someone to actually go and weigh one, they would have to unstick their a$$ from their chair in the age of internet to do so. :D

how much does the orignal horn weigh?

I don't know first hand how warm that R/R gets but air flow might be on the needed list, is that location the best ?
 
I mounted my R/R to an aluminum plate at the back of the battery box. I run a smaller battery so there is room for lots of stuff. Another great location is under the air filter.
 
I’d say putting the Shendengen r/r in the stock horn position is doable...

The trick would be to start with the shendengen unit... and then assemble the rest of the bike around it...
 
Thanks LAB / Time Warp;
I have a beautiful Stebel Nautilus horn (made in the UK :D) that i want to use on my next build, but it will not fit down there. the shendengen R/R will fit, and there is plenty of air flow through that location. the Shendengen only weighs 12oz

The original horn bracket is a solid plate of steel, in a sort of triangle. It would be way overkill for mounting an R/R. Mine horn was easyish to remove when I had rear mudguard off and wheel off. I replaced it with a Fiaam FreewayBlaster...which I have used on my other bike to excellent effect in downtown traffic. Mounted in original location but using its own bracket...have heard that is important since bracket and horn work in resonance to generate best output. Best $19 to spend on my bikes!
 
I've had the Shendig r/r on my Mk3 for a couple of years now and it barely even gets warm to the touch. Mine is located in the battery compartment (Shorai). Heat is not much reason for concern as far as mounting goes.

The horn location on a Norton is just plan stupid. Who thought that one out should be shot

No doubt they went on to the front disc brake wheel offset followed by the directive to come up with a brake that felt more wooden than a wagon wheel.

One theory is that early disc brakes were meant to mimic the wooden feeling of drum brakes as not to scare the customers. Also remember that tires of that vintage were not as sticky as what we can get now so locking up and sliding the front wheel may have been another concern.
 
I'm not sure why the drama about the location of the horn is going on. I dont have a problem with it. I simply slotted the 2 holes at the bottom of the guard so that [ after removing the rear wheel ] when I remove the two nuts holding the guard at the bottom, then remove the single bolt above them, the guard rotates downwards and away from the horn. [ the 2 bolts holding the horn bracket have to stay in place, as they are used to hold the guard as well. ] Horn is easy to get at then. I have mounted another horn beside the rectifier, and facing the side cover though. My 2 horns now sound like a 60's British cars 2 tone horns. I have had instances where one horn has not worked so having two helps when going for my 6 monthly Wof Inspection.

the original question was; "I binned my old horn, but now need to know how much it weighed. i want to locate the shendengen R/R in the horns original location". - and has been answered.

interesting side note; the original horn was dead, i had a nice Hella electric on the shelf, so mounted it in the location. in the open air the hella was massively loud, but once bolted down below at best all it would produce is a gentle beep.... so the horn had to be moved. now it has attitude and volume... since the hella single tone unit has no acoustical horn scroll and relies only on the vibration to produce the sound, i'm guessing that the mounting bracket just absorbed the vibration.., anyone out there who is much smarter on the workings of a horn??

As I eluded to in a previous reply...many automotive horns are tuned to work in tandeem with their mounting brackets to create the proper resonance for optimum tone/volume. Mounting to anything other than the spec'd bracket will change things, and not for the better. I would suspect your high quality Hella unit was not getting it's intended resonance if you mounted it on a stock Commando bracket.
I've mounted a low cost ($19 at C.T.) Fiamm FreewayBlaster to the stock location but used the supplied two piece stamped metal bracket and it is teeth shaking loud while on the road. It certainly gets the attention of cars/SUV's at highway speeds either side of me. So the location in front of swingarm is not a problem.

i made the paperdoll template and positioned it, if mounted horizontally as i planned, its' to long and bumps up against the rear iso tube.

i will try an offset vertical mount and see if i can clear the oilfilter bracket...
