    Default Accuracy of the Trion Protractor

    My protractor wobbles in it's slot when not locked down. I needed to cut a 90 degree end the other day and to change to cross-cut mode for one cut is too much hassle. But the accuracy of the cut was not guaranteed since there is so much sideways movement in the sliding protractor, thus making it impossible to cut 2 ends exactly the same. Is this normal ?
    I may get a cheap mitre saw for such jobs, seems the only solution.

    Gumby, I had a similar problem and now only use the pressure finger on the protractor when ripping, and I don't use the mitre guage functionality at all.

    Even though I adjusted the protractor in the slot, I still was not happy with the residual lateral movement - I opted for a crosscut sled on the WC that solved all of my problems and guaranteed me repeatable accuracy.

    I seem to remember that there is a way to firm up the rail in the mitre slot that is demonstrated in the Triton video. It involves hammering the rail in some way but, sorry, can't remember the detail.

    One of the Triton buffs will be in here to tell you, I am sure.

    If all else fails, buy a pack of plastic playing cards, cut them into strips the width of the mitre slot depth and slip a couple of strips in alongside the rail each time you use it.

    yes the solution is on the setup video.

    From memory goes something like:
    remove mitre from WC
    Undo the triangle part of the mitre guage from the track runner (two little bolts I think)
    Turn the track runner onto its side and place on a hard surface.
    Using a hammer and a broad centre punch or 1/4 inch long bolt, lightly tap the 'fins' (the bits of the runner that engage the track) so that they move very slightly closer together.
    Put all back together, and test guage on table.
    If it is too tight to slide along now, the 'fins' can be spread again using a screw driver.

    Good luck

    I love work, it fasinates me, I could sit around and watch it all day.

    Geoffrey is right about the adjustment, the video also mentions that you should press down on the protractor as the grooves in the aluminium slides are there to help guide it.
    A tip, I have borrowed the video from the library for free, and after a couple of years with the 2000 it's amazing how many little things you forget. ( or bad habits you develop)
