    Default Table Saw Fence Fine Adjust

    My table saw had a rudimentary fine adjustment system for the fence. Just an M8x1.25 bolt running in a very sloppy threaded hole in the aluminium fence.
    It had a huge amount of backlash and 1.25mm is a stupid pitch for a vernier. I had a 9x1mm tap and die so I made a new bolt out of a piece of 19mm Stressproof. The nut is PB1 bronze. I single pointed the thread to close to tolerance then ran the die over it. The result is a very snug fit with negligible backlash (for a woodworking tool anyway). My dividing plate doesn't have any multiples of ten, so I printed off a template and rigged up a Heath Robinson pointer.

    The fence is now much better than it was and I have a 0.1mm 'vernier' on my table saw fence. Should have done it 25 years ago.

    G/day Chris, it's crazy that the manufacturer didn't put a 1mm thread there to start with, nice job m8.
    Did you get that Stressproof steel locally?

    Thanks John.

    My model diesel engine plans called for Stressproof for the crankshaft. I contacted Niagara Lasalle about an Australian importer. There wasn’t one, so they sent me 6 x 6” lengths from the US free of charge.
