I'll just say this: some people have time and some people have money. Few have ample amounts of both. Yes, I have a hyperfirm but I can also afford to drop $225 on a blaster whereas finding a free weekend to work on a prop is pretty near impossible, and given how much I make per hour it's more cost effective to have people build my props than me doing it myself usually anyway.
For my $.02, Pat did a phenomenal job on this blaster and I'll agree it's that it's worth creating a tutorial thread about. Is it a de-act Sterling? No, but he didn't punch out $500 on it either. I thought he was very creative and the results are great.
As for the German part - my grandparents spoke German at home but I grew up in a very mixed neighborhood where racial & religious epithets were common, so being called the "good German who keeps the trains running" wasn't taken as a negative, as I used to sling the same in return back to my friends.
That said, I recognize not everyone was blessed to grow up in a place where the Germans ate Chinese food and the Chinese ate Mexican food and the Mexicans at Greek food and the Greeks ate at the kosher deli just like everyone else in the 'hood; black, hispanic, white, etc.
As such, I'd advise not presuming others are OK with monikers unless they've blessed such a nickname in advance, lest tkrestonva is forced to do what he does so well.
