Almost a shame to cover it with a cabin! I'm sure you'll make removable, but it's been a real treat to watch the model evolve through the last couple years. It just keeps getting better and better.
I will say I've learned a couple things from your machining process photos. Fixturing and drilling those tiny holes. What kind of adapter are you running for drilling the rivet holes? It looks like a mini chuck, but you are supporting the bit with a free floating collar of some kind? Any more info on that?

Great looking work on the dragline!

Thanks guys. Been wanting this part done for quite some time.
Espeefan,Pugs is correct on the sensitive chuck. I had to use it because I couldn't get all four plates to hold down tightly together. I broke a couple drill bits before I used the finger chuck.
I intend on covering the frame and have some of the panels removable, but it will take a while still because I still need to make the curved roof trusses and the operators cab that contours with the main roof.

Glad you noticed my simplified parts. When I started this machine several years ago, I never dreamed I would be building this as close as I am to the 1:1 Help from others and getting permission to crawl all over the 1:1 has made a huge difference on my build.
