    Hi Folks,

    We have received a granite surface plate that we ordered from RDG Tools and on unboxing it appears that there is a very fine crack running across the top of the plate. I cannot detect anything running my nail across it, but has anyone experienced or seen anything similar on a granite plate? It is very hard to detect if it is a crack or just an artifact in the natural material. Advice appreciated :)

    The only thing I can think of is dye penetrant testing, that would definitely detect a crack if there is one,

    If you will not be swayed by logic or experience simply pick the idea you
    like best, but ask yourself why you sought advice in the first place and,
    for a simple life, perhaps consider not doing so in future

    Also if you suspend and gently strike it with a plastic hammer it won't "ring" cleanly if it's cracked

    Thanks Nick!

    Not sure about this idea as its pretty heavy but I have used crack detector kits in the dim and distant past. Will do a search and see if I can find one that is suitable and fits within our budget ie cheap :)

    Wouldn't accept it my self and send it back. I've never seen crack or defect in any new surface or lightly/correctly used surface plate that is designed to hold any sort of precision.!
