    I would mark it out of the mortise on the board and use a trim router to get most of it out. From there you will have to move to a chels to get it finished.

    Well, now that you have a plan of action, how about clarifying what you were trying to do; I am a little slower than the others. Were you trying to put a tenon or mortise in the end grain of the rail shown on the bench? I am going to guess tenon, but I don't know. If it is a tenon, then you were also going to cut back the slot to match the face of the tenon shoulder, right? Just wondering.

    TENON

    If it is a tenon, then you were also going to cut back the slot to match the face of the tenon shoulder, right? Just wondering.
    now your aqsking me something i dont understan bill the blue tape represnts the mortise postion. the tenon is going to have aproximatly a 1/4" to 3/8" shoulder bill.. but its running at an angle to the any flat surface this rail has.

    Hi Larry.

    If I understand well, what you want to achieve is to make a tenon on the same place on both ends right?

    I guess that you have a template of the profile that you have used, right?

    Using that one, cut another one drawing on it the desired position of the tenon, in the same way that you have simulated on the pic with blue tape.

    Cut out from it the square hole that will be the tenon. Then place it on the end of the piece and mark the square.
    Cut the tenon following the square lines end grain first to the desired length of the tenon.
    Then cut cross grain eyeballing the depth until the pieces fall by themselves.

    Then pare with a chisel for a perfect fit.

    The most problematic is to have both end tenons on the same place and orientation otherwise the whole piece may become twisted when assembled.

    I hope I explained it properly, I know how I would do it, but maybe I can't convey it well enough.

    An easier way would be using thick dowels, but you still would need to make sure to aling both sides when marking so that they do not become twisted.

    I hope it helps.
    Best regards,
    Toni

    BTW.

    Are you shaping it with that nš4 plane? Don't you fear about not making it straight?

    I'd use a nš 7 or 6 at least, unless you've marked reference surfaces that will not be planed. You see I'm not that good a planing long pieces.
    Best regards,
    Toni

    larry, if its a through tenon, drill a hole larger than 1/4", then (not knowing if you have one handy) take a saber saw, and cut to a hair inside of the line. that way you can adjust the mortise to the tenon.
