......and the written description for the above photos... jeez this will sound complicated!!!
The Thersby frame came with a T shaped front Fairing holder, I could have bent this to the shape of the fairing but it is extremely tough steel... and I didnt want to have to resort to heat treating.
I used a piece of 3mm x 30mm alu flat bar long enough to mount the lights (obviously!) this is flat on each end where it is bolted to the Thersby T piece (which was cut down in overall width) with a little bit overhanging to bolt the lights to! And bent outwards in the middle where I used a rivnut which secures this to the fairing (with a rubber washer bewteen it and the fairing)
This is secured to the T piece by 8mm bolts (I used the flat headed ones which came with the Carellos) with a rubber washer in between it and the Thersby T piece to dampen the vibration.
I had some aluminium shaped spacers knocking around which have an 8mm bore these are around 30mm in diameter but step down to 20mm I had a couple of 30mm rubber grommets which fit perfectly over the alu spacer so I made 28mm holes in the front fairing and the grommets fit nicely in there too..this means that the spacer is damped for vibration against the fairing.
The carello's came with U brackets in which I drilled four 3mm tapped holes and secured them to the back of the light housing with a couple of pices of rubber inner tube as a vibration damper. I doubly secured these 4 little bolts with dome nuts.
The U brackets where they originally fit over the holes in the lower rearside of the light housing are slightly concaved on the inside faces and serrated to grip the light housing. I cut a piece of stainless tube and rounded it off so it fits inside the U bracket..... to this stainless tube I welded a long stainless steel bolt. This is secured to the bracket with the original carello 8mm bolt which has a lug on it which fits into a slot on the bracket.
Finally I drilled and tapped a 3mm hole in the head of this bolt to secure the earth lead of the light.
hope this all makes sense!
