Like I said earlier, this Comet HD-5 (I think that's the model) seemed sturdy at first but ended up breaking last year on Imogene pass. Apparently, a 4' Firestik, HD spring, and quick connect are just too much to handle on a rough road. I fixed it using what was available at the Ouray hardware store and it has stayed that way since.
Where the big silver fender washers are used to be a thick machined washer. Unfortunately, that big thick washer is what broke on the trail.
I cut this piece of 1/8"x1.5"x1.5" aluminum angle stock and ground it down to this.
I applied some 3M VHB double sided tape to the "feet" of the bracket I made then painted it black. Originally, the Comet mount used a small metric allen screw and threaded into the end piece. I drilled through that end piece and used a longer stainless steel 1/4" bolt that goes through my bracket as well and secures with a stainless steel acorn nut.
The Comet mount is now very sturdy and held up great on the rough roads in the mountains around Ouray, CO. It doesn't stick out much further than the Comet already did. Hopefully, if someone else is having trouble with their Comet mount, this can give you an idea of how to brace it a little better.
