I'd definitely go for a more substantial spindle. Proxxon and Metabo make
excellent small spindles or you could use one of the better grade trim routers
(Bosch Colt, Dewalt, Porter-Cable, etc.) Also check out the precision collets
available from Precisebits.com. These will greatly reduce the runout and enable
you to use small diameter bits.

Subject: Re: [Emc-users] Engraving Tools.
Hi All:
Here's a question esp for the XY routing table folks. What's a good
'dremel'
tool to survive the side loading of engraving on alumnium? I want to make face
plates for electronics enclosures, so text, numbers, outlines etc. That means
small end mills and high RPM's. Maybe even nameplates and the such. I'm
designing a clamp on mechanism to allow me to mount a 'dremel' tool shotgun on
my z pillar and just vary the z axis like +/- 100 thau at most. But that side
loading seems to me would tear a dremel apart.
I see the XY table crowd uses them. What approach should I take? The $30
special from Horrible Fright and just blow through them? Or sink $100+ into
something that will last me more than a few projects?
Your thoughts?
Andrew
