Ed,
I believe the tabletop that you're looking for is extinct. I can't remember the name, but we tossed ours because we couldn't get parts, and it wasn't worth the machine shop. The ususal suspect now is Excellon Unidrill. We have two- one runs, one for parts, but they are very reliable. Enter your search criteria at Ebay and wait about 3 months. Expect to see other bidders. Shipping will be major cost. The spindle has been resurrected by Precise of Racine Wisconsin (in no small part due to the Unidrill user requests). I think it runs about $5k with controller. If you build one yourself, that is a good choice of spindle.
Struers has the current day popular replacement. http://www.struers.com/default.asp?top_id=3&main_id=11&sub_id=116&doc_id=537

This isn't even close... what I've worked with (but dead brain cells
blocking access to memory) was a "manual" tabletop setup.
Thanks!

Ed,
We had a couple of fancy bottom drills when I worked at Fortin. We
spot-faced down to the inner layer targets then used these drills made
in
Switzerland to drill the center of the target. The customer used that
for
set up tooling and could drill with these.
I want to say the manufacturer was Posalux.

[TN] Bombsite PCB drill

Hi fellow 'netters,
I took a job up here in the Silicon Valley. I've been lurking, but not
participating much. I must say, it's good to be back!
I've been looking for an old school pcb drill, bottom up configuration
with a magnified bombsite optical alignment, typically was used for
homebrewed prototypes.
I've scoured the www and cannot find a current manufacturer.
If you might have one (or know where one is) I'm very interested.
Any help would be appreciated!
