rev counter needle

just come from a weeks holiday to find my rev counter needle is not attached to the blimmin rev counter! any ideas? can i get the glass off? or is there anyone who has had this problem and fixed it?

my needle fell of the speedo. the clear cover is silconed on so i ran a screw driver around the groove ans prized the screen off gently and re glued the needle back on and re siliconed the screen on

cheers will try that today!

rev counter needle fixed!Thanks Mike.
