Hello philo426!
Good to know somebody else is building this! Watch out, this model is peppered with errors, some things, as shown in the plans, just don't make no sense at all, like for example the chain plates. I still have to finish mine after five years (granted, I only build it in the summer), but maybe I could help you if you have any questions. Here's a photo of my build:
