Thanks, chuk, you're SBS is amazing, truly amazing! The engine looks fantastic, and if I didn't know that this is a 1/48th model, I'd think that that is a large-scale model of the engine.
My hat is off to you, really, for the super attention to the details. There are so many things going on, it'll take a while to analyze it for the lessons.
One tip I picked up from this latest installment, is that I have to get Mr Surfacer. Up to now, I've used Squadron putty. I often thin it with acetone and brush it on, but it's still so thick as to require sanding to remove the excess. That means more scribing, to restore lost detail. But your up-close shots make it Mr Surfacer look comparatively easier, with a cleaner result.
Waiting eagerly now for the next installment...
Regards,
Brad
