Subject: Re: [Homebrew_PCBs] Drilling

You are best off building yourself.

The drill travel is very short, so you can get away with a pivoting
swing arm. Make it like a triangle with the drill on one point, and
two bearing points on the other two points (or a piano hinge along the
edge). This is very stable and won't break drills. Spring load so the
weight of the drill and arm is balanced and you can easily move it.

You need a vacuum attached to keep the dust down, and a spotlight.

I have a cheap drill press which is barely adequate for occasional drilling, but there's enough slop in the quill that it's extremely difficult not to snap off <1mm bits. I've had the best results using the manual mill at a friend's machine shop but it seems silly to use a 3HP spindle to turn a .85mm bit. I almost bought one of those little Dremel stands since I have a couple of the rotary tools but I've heard they are flimsy and don't work well. Is there a good low cost option or am I best off just building something myself?
