  • Milling/Engraving wood with my cnc knee mill

    I have a craft-like project my wife has come up with that is making a personalized clock. Rather than buy numbers and letters to make the clock face and personalization, I said I could use my mill and basically v-carve these items. The top speed is 4200 rpm. Could I use this with a 3/8 or 1/2" HSS chamfer mill to do what I'm wanting?

    Thanks.

    I V carve at about 15-20,000 rpm in woods with a slowish feed rate
    Try using your mill on a scrap piece of timber similar to what you are going to use
    Your biggest problem will be scorching of the wood
    If you can get a 60 or 90 degree wood router bit that may be better

      I found I wanted more spindle speed to cut it really cleanly in wood. So rather than cranking my spindle overspeed and compromising I made this.

      And moutned


      Its for making quilt pantographs, here's a quick test.

        MrFluffy, I thought about making a bracket to mount a router to the quill but I wasn't sure about the torque on the quill from the weight of the router. It looks like you are using a small-ish trim router similar to this Harbor Freight dandy and it only weighs about 4 lbs. What is the rod in the middle of the bracket for?

          That's an additional support- it goes to a boss on the spindle housing meant to hold an indicator.
