great tool! simple efficient, i`ll definitely make one and post here. don`t know if i`ll be able to find a block of plastic but if i can`t i`ll make it of metal and add a window for light to enter or put a small led, i`m complicating the thing but the local plastic supplier only stocks sheet (i`m on the end of the road). thanks man.
