  • 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!

    Yeah, the 3003 has a lower yield strength but does have good characteristics when it comes to forming into profiles and complex shapes (We were making polymer extrusion parts). The aircraft aluminum will have higher ksi, but formability will be limited. It is an exercise in material science to...

    I can remember forming some ‘flow tubes & couplers’ about 20 years ago and the grade we used was AL3003. Better formability and a lot less expensive. I remember buying from Ideal Alloys (now Ryerson). What grade of Aluminum sheet did you use ?

    I recently found that ‘photo’ (jpg) files, are not attachable to conversations in April 2025. They are attachable to this conversation that was initiated back in March 2025. Is this what others have been experiencing ?

    We used ‘polyurethane foam insulation’ on some applications to muffle noise. Probably would not stand up to hot areas in the engine compartment, but, the foam has good structural properties for stiffening purposes. One neighbour has used it to reinforce his GLIDER segments.

    Nice work Ryan !! I wish you were around when I was developing ‘aluminum moulds’ for extruded HDPE pipe. * You are going to find a lot of interest from the Home-Built aviation enthusiasts. Might be a little work on the side for you ?
