    Good afternoon.
    Has anyone designed and/or manufactured and used their own "after market" spindle/router mount that provides an easier method of tramming the spindle in both axes? (both left/right and front/back).

    Thx, rink.

    The reason doesn't really exist is that adjusting the router mount fixes the angle of the router - but does nothing to correct the axis of motion (far more important)

    The now upright router still enters the material at an angle as the Z axis plunges at an angle, because (for example) the Z uprights were installed skew.

    See Tramming: A generic guideline

    Fix the problem, not the symptom :)

    Hey, Peter, thank you.

    Yes, sir, I do understand the difference between the X/Y axes of motion vs. the alignment of the vertical axis of the router.

    Of course, first priority is to ensure the X/Y axes of motion are aligned correctly. And even if those aren’t perfect, but very close, it should be OK if you surface the spoil board to be parallel with those X and Y planes.

    But even if those planes are aligned perfectly, the vertical axis of the router could be off, correct? Either front-to-back or side-to-side?

    Your message above seems to imply that, if the X/Y axes of motion are aligned correctly, the router will automagically be aligned correctly. Did I understand? There is no slip or play in any of the screw holes or brackets that could affect the router axis independently from X/Y axes of motion?

    What am I missing? It’s something simple, isn’t it?

    Basically yes, as explained in the generic guide. The mount itself has a little left/right adjustability (but can be squared to the Z axis carriage precisely during assembly)

    It would be nice if you would put out a video on this so everyone that owns an openbuilds machine would know how to do it. It is a big problem. Every other brand has videos on this subject put out by an owner or the company that made it. Not for open builds. I have not found one yet. Please do that for us so all owners are on the same page. Thanks

    I made something like in the link below but didn't clamp the pins just screwed them.
