I'll show you one of the projects I'm currently working on. I wanted to do a Pz 4 for some time now. It will be a non specific east front panzer.
Basic hull build, wheels are pressed on with the help of some tissue paper.
Front, with some tweaking everything lines up nicely, even the add-on armor has weld detail. Be carefull to use the correct font plate (E19/E30) in combination with add-on armor, the instructions are not to clear on this.
Side view, gluing that support wheel was not the best move. Luckily I did only one of eight.
Detail shot. Only a little putty is needed (side plate is a single plate)
The damaged third wheel was made with an outer rim out of the spare box that was glued to part A19. The wheel can be found as extra item in the early Pz 4 kits (C, D & E)
The rear. Had problems fitting the parts so I changed the build sequence a bit. I first glued E11 to the hull, than E26 and when the glue had set a bit E13. This way everything lined-up straight.
