    I really like your dust shoe design.

    Do you have easy access to the collet for tool change?

    Re: What downcut bits have a good tool life?

    I ran Yonico and Onsrud 57-xxx serie with good success but Onsrud finish is a tad better and last 25%-50% longer. Yonico is almost half the price of Onsrud depending of vendor.

    Re: Z²

    Will you laminate phenolic to hold your rails as you did with the Z axis?

    How will you make rails on both side leveled on the same plane?

    Great to see this project active again!

    Re: Spindle Recommendation

    That would have give less area to glue the small torsion boxes to the big one and I still would have had to level the two sides.

    Re: 40mm finnish birch plywood CNC-router

    Maintenance will prpbabpy be a pain with the holes. If the holes are bigger to help maintenance, it will make your gantry side less stiff.

    It probably make the problem worse. What is "lower feed rate"?

    I had this router on my first machine and the lowest rpm is around 10000 rpm.
  29. Re: Very rough surface finishing recently with c-beam build

    Feed too slow, too many flutes, RPM too high, DOC too big. Recipe for disaster.

    This looks like my first attempts with alu.

    What is the rpm, feed and DOC you are running?
