I sure don't make time to update these blogs...
Here is a video update from the first weekend we had the new K321 running!

At this point, half way through winter, the 312 is tucked away in the shed. I fired it up today, took a bit of cranking but then off it went.
Over the past summer, I've made a good start into building a mini-loader, more info to come this spring.
