Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Ontario GTA West area meetup is planned for Saturday April 26th at Greasemonkeys shop in Aylmer Ontario. If you are interested and haven’t signed up yet, click here! Arbutus has also explored interest in a Fraser Valley meetup but it seems members either missed his thread or had other plans. Let him know if you are interested in a meetup later in the year by posting here! Slowpoke is trying to pull together an Ottawa area meetup later this summer. No date has been selected yet, so let him know if you are interested here! We are not aware of any other meetups being planned this year. If you are interested in doing something in your area, let everyone know and make it happen! Meetups are a great way to make new machining friends and get hands on help in your area. Don’t be shy, sign up and come, or plan your own meetup!

yeah they are stupid expensive... but when you make models you want very accurate tiny holes.Or if you want new:

Why not go collet route - either jewelers collets or ER11 - the drill can be small but shank can be 1mm. Quality set should not have runout more than few tenths.

I don't have a drilling machine that is delicate enough, which is why the sensitive drilling shank is desirable more than the chuck itself.
What I really need to do is make george thomas' universal pillar tool with the sensitive drilling attachment... I've wanted one for at least 30 years

Depending on what you are drilling, cannot you place a small drill in ER11 1mm shank and then have the ER11 as a straight chuck which is in a *well made* tube that attaches to say your lathe tailstock? You feed the drill by hand - so you feel it - sensitive drilling. the ER11 chuck is ground and the tube it goes into is at least reamed. That is setup similar to what I have and should allow drilling of tiny holes.
Or are we talking about same thing, just you call it differently and I have it horizontal and you vertical?

I'm talking about vertical drilling using small drill press or similar device. If I make a pillar tool I can use any system with the spindle I want, so collets would make a lot of sense.
I gave up on finding a high quality sensitive chuck very early in my search and ended up making my own using a small Chinese chuck. I reasoned that the minute you start holding a darn small chuck in your fingers, the precision is all shot anyway. Maybe that makes sense, maybe it doesn't. But that's what I did.
