Rush?
I've got 4 kids, man, my whole life is a rush!
No, really it's no problem...my local hobby guy has some data sheets...& I have some other stuff I need to pick up from him anyway.
I'm not able to make my own decals...I have the "Yugo" version of ink-jet printers...

I think my wife finally bolted it to the table, because everytime I use it, I instinctively want to throw the %$#@ thing out the window!
I've got some alphabet sets around here, & I think I can come up with an EVM logo...besides, I kinda like the challenge!

As far as Hogwarts...we have to work on that before my little one's bedtime...after hours means time for N scale! This is
precisely why I'm a big believer in
small layouts!
I can't put a deadline on anything, but I'll keep ya posted!
