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!

On my project list is a 3 gauge (triangular) spindle square for tramming all three axis (x/y/nod) simultaneously. It's been on my list over a year now with almost zero progress. Maybe I should bite the bullet, buy one like this instead, and get on with the joys of getting old....
There are less expensive versions out there, don't know anything about quality or accuracy:
Spindle Tramming Square
Pro Tram by Edge Technology makes the process of tramming your mill fast, easy and accurate. Tramming is the process of squaring the head of your milling machine to the table. Browse on selection of different shank diameter and indicator size.

Also this one, out of stock & no price listed:
Thank you. I've looked at units like these before. What I was originally after was something I could use for tramming nod as well as x/y. Nod is generally harder to do because the center of rotation is not coplanar with the spindle so changes are quite different between any two positions with the near indicator showing larger changes than the far indicator. It's easy to end up chasing your tail.
I had thought that a 3 dial indicator system could make shorter work of the problem using my brake rotor to straddle my vise and providing a continuum of readings 360 degrees around the spindle at a 5" radius (10" diameter on a 12" brake rotor). I just never got around to finishing the prototype. I made the lifting blocks and I polished the brake disk, but I didn't make the 3-gauge spindle square. The imperative to repair farm stuff got in the way of doing the design and build of the triangular square.
I think if I abandon the 3 gauge system and just use 2 gauges, it might indeed be easier to just buy something. But I'm not thrilled with the short span on any of the available devices. But, by the time I get around to making my own 2 dial system, I could prolly have made a 3 dial one.
I'll have to think on that for a while.
Thanks again for the links.
