    Bill, I accidently came across your podcast in August. Because of it I have now built a CNC machine and am learning all the ins and outs. Thank for the inspiration!

    ps. I am buying my bits right now, are there any “go to” sizes that no CNC machine should be without?

    Hi Bill,
    A word from Stendert from Holland,
    I discovered your podcast, listen to every cast it stimulated me to buy a second hand wooden cnc,
    I’m learning Mach 3, Vcarve pro, so it’s like going back to school.
    I want to thank you for the inspiration and please go on with the podcasts,
    Best Regards,
