I used the bigger cutting wheels for the dremil, not the little ones.
I'm sitting here looking at packages of both right now.
the number 426 are the little cut off wheels you change with a little screwdriver.
It'd take lots of them to do a proper job, maybe 4 or 5.
I use the bigger E-Z Lock ones (1.5") only takes 1 of them to do the job.
Myself, I just followed the line Triumph so graciously provided.
Had to redo the back mount as it was gone in the process,
but that ain't no big deal, and I think it looks ok, at least it's "different"...
Just about ready to take a picture of my new headlights...
you want to see different?
just wait....
my wife asked me years ago when I started doing mods,
"Why didn't you just buy the bike you wanted"
i told her "I did", "now I just gotta make it MINE".
i don't think she understood at the time,
but she's starting to now.. (I think)
