Re: High Speed Spindle for SIEG X2 - Finally a Solution

Graham, again thanks for the information. Have you ever considered
an internet RFQ business process for solving technical problems,
especially electronics? You really should think about it. Graham,
you are a gold mine of information. I looked up Rab Gordon's web
site (www.rainnea.c..) - that is exactly the kind of engraving and
sculpting that I will be doing, so you can see why I am interested
in high speed machining technology, high speed spindles, and small
diameter end mills. A person could do some of that kind of work
with the KDN Tool CNC conversion to the Proxxon MF70 micro mill. I
purchased Daniel Carr's Designs Computed VS3D software to do the
CAD, and CAM for the designs, and generating the G-code. I've been
waiting to find the high speed spindle solution. That's why I am so
excited about the KDN Tool Proxxon IB/E for the SIEG X2. Is Rab
Gordon's "little double ended brushless spindle" a RC motor? Maybe
like the IRK Torque Max.

Again thanks for all the information, and God bless you.
