Re: Mini desktop CNC mill to engrave custom center caps.
You could probably get away a LOT cheaper than a Taig, too. Check out the Probotix Fireball V90: FireBall V90 CNC Router - You would not need most of the options for what you are looking at.
Or track down John Hansford, the original designer of the V90 (he is NOT affiliated with Probotix any more, sold them his design). He makes systems and sells them for less than it would cost you for materials!
