Almost soiled myself lol
Hmmm, I'm probably not a great builder...although I have built 1/2 dozen or so 'dory's", those double ended cod fishing boats, real ones, not models so I'm very familiar with compound angles....nothing's square on a boat.
So the same with rocket tubes....round.
I am pretty good with finishing work though, albeit with a paint brush or roller...now I've gotta get used to an airbrush...again...np...old man had one he used on the old RR kits with a can of air...used one then, I'm sure I can use one now.
Some things just stick in your head like your Regular Army Number...and you just never forget.
