    CNC routers and 3D printers work for more than building parts. If you look closely at my elevator trim picture in my post above, the ball screw mechanism is a part from a 3D printer.

    I've been using a CNC router for a few years for my Hatz build. I have cut plexiglass, wood and now aluminum. Depending on the max size you want to cut, a small 12"x24" CNC router will cost less than...

    I had a lot of the 4130 parts for my project cut with laser and some were water jet cut. The laser cut parts didn't need any post processing other than I took the edge off with a 3M wheel. I asked an...

    Making the joint fit is probably a good thing to do. Sanding to fit with a course sandpaper will create a rough surface that the glue can adhere to. I usually just knock the dust off by tapping the...

    I was just correcting the misinformation from WLIU. Every few years I get some additional training to keep from forming bad habits. If I obtain an endorsement or two on the way all the better.

    A couple of opposing views. Got me thinking. I also did get some local feed back. One example given was a map. It's difficult to create a new map without using other maps. A map is copyrighted but...

    You can get 5gph out of an O320 with electronic fuel injection and ignition. When I'm chasing C182's I get 5gph at about 145 mph in my Glasair II. If I'm cruising WOT (Savvy style) and 2400 RPM I get...

    For a minute there I thought he came to Canada. GPS works here unless you go too far north. The far north has never been charted. You have to rely on GLONASS. ;)
