Re: [CAD_CAM_EDM_DRO] Re: High Speed Spindle for SIEG X2 - Finally .... ... just a nagging doubt ?

Hi Chris,

that IS a nice way to handle them. I thought of mounting a Dremel
alongside the Sherline's spindle to do something similar a few years
ago. But a Dremel isn't really up to the task.

My boards are 3" x 4" at this time; the limit of Eagle 1st level. About
one at a time for now. the PCB router I'm working on should give me a
few more options.
