  • 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!

I've done some amateur act airbrushing with templates & I'm struggling to understand why you would want something thick like coroplast for the spray template itself? Typically masks want to be thin to preserve the sharpest edge possible. Think typical masking or striping tape. Thickish templates have another downside & that's the vertical wall holds wet paint, so if it has sufficient buildup, can back flow down & smear muck up your work. Are we talking the template or the sign material? The stencils I've seen are like 1mm thick mylar (or one of those tough plastics that are solvent proof). Thin templates can also wrap around curved surfaces a bit if that's a parameter.
 
I'm using a piece of 1 mm plastic salvaged from a projection TV. Milling plastic is definitely a learning experience. Last attempt it probably cut about 50% of the time and melted the rest. Came out ok tho.
