Phenomenal work! I have to ask, what kind of superglue are you using to attach the tubing to the body? I struggle to get a good bond and whenever I try to do body work around it I usually just end up breaking it off with my shrek hands.
Wow, your work is incredible. I've been a long time lurker of this forum, and because I want to save a record of this thread I finally joined. Curious to see how it works out because I've been considering building my own model farm equipment.
