i was lucky to find a chap (wicky) who took on the challenge of producing one for me and as so i had very little input in its making and i think wicky did a great job
.right the clocks this is as you know the cluster
not very nice i know and this is why i wanted matching dials (all white).
to start with you need to remove the 3 bolts holding the cluster on , one left side and one at the bottom and the last one on the right ,
.now you will need to undo the two black connector plugs on the back and the cluster can be removed from the bike .
now to remove the cluster face turn it over and remove these 5 screws
.now lift the front off the backing
.now to find the natural resting position of the needle to do this carefully lift the needle over the stop and mark the face on the side so you can transfer the mark to the new face .
take a picture of where it lays as when you refit the needle you want to get it back in the same place .
now the fiddly bit
needle removal .to remove the needle i found it easiest to use a fork yep out the knife and fork draw .
slide the fork under the needle and with a little tug it pops right off
put it somewhere safe or paint it to match the others its up to you .
now you need to remove the two Phillips screws either side of the needle , now the face will come off.
.now the fiddly bit number two
pin removal .this is a pain in the ass if you loose it
now the best way i found to do this is using a white carrier bag without holes in the bottom , turn the face upside down and while holding it inside the bag use the flat side of a dinner knife press against the back of the pin and it will pop off flying into the bag 
woohoo half way there
but your tool box seems to consist of cutlery and a plastic bag
