SkyHawk, it just comes with practice and ingenuity. I just attack plastic with a hobby knife, ruler and a sharpie and tanks randomly appear...
I did some more detail work around the turret. So far so good, not perfectly scale but she'll do! I need to seal up the gaps between the upper and lower hull still with some sheet and it'll be basically ready to start painting and working on electronics... this beast will be getting a Clark and be built for combat
Also note the exhaust cages... I bought a sheet of brown needlepoint plastic sheet for 99c and it's lasted me 2 builds..! Awesome for vents, grill covers and cages of all sorts.
Next on the to-do list are the faux-spring suspension that is typical of Japanese tanks.
