Making a Large Plywood ‘Cast Iron’ Cog

I often say how much I enjoy a project but this one really was a fun one. It was much easier to make than the original wooden cog that I made a while back as there wasn’t any joinery involved. I’ll make a few more and connect them up to my propeller. Fingers crossed, it may actually get the prop turning although I’m not super confident about that. Either way I’m enjoying making them and it should look great as a display even if they don’t actually work.
