Great info Dave thanks.
I always wanted to do a tank they have so many great details to model. I have seen several tank models that are just awesome. lots of surface details. Yours is turning out to be quite good as well.
I am very impressed we are pretty close in age and you have mastered a much broader range of tools then I have managed.
Keep up the good work someone needs to stand up for us old buggers.
