  1. You could shim it apart just as easily as closed. That would make it nice and stable.

  2. Yes of course I could.... i was looking at it this way... the thread is 8tpi, 3mm. the kerf on the saw is 1mm+. The backlash is 2mm (yes, almost a turn). So I could shim it out a lot, or mill it down and shim it back out a little... but obviously I'll try the former first....

    SKF Dormer make quality jobber bits.

    If you really want a 7mm hole grab a 6.7mm bit.

    Don't start with the 6.8 because it's probably blunt being the M8 threading size

    Threading size???? I normally use a smooth sided pointy bolt and a hammer or super glue to hold things together or a hammer or a few grams of PE :naughty: to take things apart. Mind you my subject matter is almost always organic in origin.

    PS ... Black Maskers was always the first option for fixing things ... The whole of the MOD is held together with Maskers ...
