This is about the last thing that I worked on for the K-27 project. I really don't do much in 1/2" anymore. We ended up moving about 5 years ago and that was the end of my garden railway. I really don't have the time to keep up with the maintenance (or construction) of an outdoor line. I used to work 4 day weeks back in the old days and it was pre-kids. These days I tinker with the smaller stuff.
I really enjoy working with the larger stuff though as it is easier to machine up the parts. I've thought about putting a loop of track up around the garage ceiling to run my C-25. Maybe that will motivate me to start back up on the K.
