• Scam Alert. Members are reminded to NOT send money to buy anything. Don't buy things remote and have it shipped - go get it yourself, pay in person, and take your equipment with you. Scammers have burned people on this forum. Urgency, secrecy, excuses, selling for friend, newish members, FUD, are RED FLAGS. A video conference call is not adequate assurance. Face to face interactions are required. Please report suspicions to the forum admins. Stay Safe - anyone can get scammed.
  • Several Regions have held meetups already, but others are being planned or are evaluating the interest. The Calgary Area Meetup is set for Saturday July 12th at 10am. The signup thread is 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!

    3d printed thrust bearing

    I printed this thrust bearing, a 2326, 50 mm OD, entirely out of plastic. Plastic races, plastic roller bearings, and a snap fit top race. See youtube below, and it's on thingiverse. I also printed it at 50% size or 25mm OD. It's interesting and will work for light load lazy susan type...

    The air assist also keeps the air clear so the laser can hit the material and the beam is not lost to interference from the smoke.

I believe this is similar to using a magnifying glass & the sun to burn wood. The tighter...

    Laser Cutter/Engraver

    Chris are you engraving or cutting out - which is the priority? https://atomstack.com/products/atomstack-a20-pro-1064nm The above infrared fiber laser unit, less than $2K CAD, seems to have good optics with a 0.03mm x 0.06mm beam. That is really small at about 0.0024". Have you looked at that one?
