    Default V Blocks

    I sometimes need to straighten round steel shafts/rods which are about 2-4 inches long and 3-5 mm OD
    and I would like a pair of small V blocks to sit under each end so I can rotate the shaft, find the high spot
    and give it a clout with my sledge hammer.

    There's no real precision needed here just a pair of blocks say an inch or bigger square with a V in them
    to lift the shaft off the deck at each end.

    Any ideas where I can get something like this cheap ?
    Proper engineers V blocks are not cheap and overkill
    for what I will do with them.

    If you twat it with an 'ammer, it will rebound a bit. Stick it in a vice and gently twat it wiv an 'ammer then roll it on a flat surface to see where it's out of true. Then repeat.

    yeah that's why you support it at each end then rotate so high spot is at the top and tap it past the point of being straight so when it flexes back it is straight.
    I have a 200mm square 10mm thick steel plate which I roll the shafts on and slip feeler gauges underneath them to measure the runout.
    It would just be easier to put it in V blocks as they wont roll around and move while being "adjusted"

    Drill a hole in a block, chop it in half.
