7/8 to 1" switches ?

Hi all,Looking through Evilbay for some decent switches  for the Intruder ? looks like
a RAT has been munching on loom or previous owner was putting back together BADLY !
after CUTTING the switches of to alter handlebars ?
found some nice ones in 7/8" but our bikes are 1" so was wondering anybody
took the 7/8 or 22 mm to 25 mm with a good old 7/8 broomstick and sand paper ?
dont seem like rocket science !
there are 1" switches available but not the set i won't !
being  my bike is a import lights come on automatically,so no need for light switch just
hi/lo ! the harley ones wiring will match, but 3 times  the price ????
Just a thought ?????????

Filing the outer casings of the cluster with a broom handle and sandpaper should be ok? as long as the internals don't encroach preventing the cluster being tightened up flush with the bars. There should be plenty of 'used' H-D clusters for sale on eBay? Suzuki 1" ones too I'd have thought?

Cheers simbo,well i got some old gs550 bits well 2 bikes actually, got the switches of that to test?
so got the 7/8 straight bars wrapped wet/dry 240 around popped micrometer on ,got it to 24mm
 a few twist later perfect
tryed on 1" bars ? fits like a glove,screws tightened no gap on edge and new grips fit perfect,
was looking at harley bits but most had still got oil on them LOL jam leakey engines,
sorry harley owners !!!!!! nothing like a good HOG   OOPS  HUG !
