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!
Mistake

After further experimentation, I am sure that my biggest mistake was going too slowly. I am also sure that my mill does not have enough power to use this cutter properly with this material.
HSS center drill - cuts like butter
1/4" HSS drill - cuts like butter. Cuts better with a faster feed
a couple more HSS drills to widen the hole to 1/2" (the largest drill I have) - cuts like butter. Cuts better with a faster feed.
1" HSS countersink - Skates on the surface until enough pressure is applied. Then cuts well for a short time. Then goes back to skating (feed to slow) or stalls the motor
I than made a make shift boring bar from a chunk of 3/8th square HSS - I have no way to grind it, so it was a very crude tool. I managed to enlarge the hole from 1/2 to about 7/8ths, but the tool is so imprecise that I don't want to get any closer even when the fit up will be with wood
This all tells me that while the metal might be bad, it can't be _that_ hard. I think I either need to find a 1" drill, or figure something better to bore with than a square chunk of HSS gripped at an angle in a 3 jaw check. Having done this once, I don't recommend that anyone try this method
