CNC routed Airplane

I made a pretty cool biplane model out of 1/4 plywood on my CNC router.

My son loves airplanes, so I cut out some airplane silhouettes from 1/4 poplar and painted them. He loved them, so I decided to build a 3d one with moving wheels and propeller.

After a quick concept sketch I went to AutoCAD to get my dimensions figured out, then cut the parts out on the CNC router. A scroll saw (much cheaper) would have been perfect for this, but I don’t have one.
One of the photos shows a sheet of ply with the fuselage parts cut out.

With some minor sanding and plenty of clamping and gluing, I finished the fuselage and moved on to the wings. This was tricky since the wing struts (1/4 dowel) go into shallow blind holes, so the dowels have to be identical lengths and perfectly square.

It’s hard to see, but the wheel struts are reinforced with another thickness of plywood between them.

The propeller is held on with a small nail and turns freely. The wheels are interference-fit onto a dowel, which turns freely in the wheel struts.

This has withstood plenty of hard usage and drops from a high-chair, and the boy loves it!

G’Day John, I’d almost say your cheating using a CNC to made these beautiful wooden toys but then again the children who receive them will be excited to just fly them everywhere; so using whatever machinery you have is prefect to making more fun for more children…top job sir…
