Hi guys,
I'm working on a Diorama where the scene will be somewhere near Budapest in Hungary during the begining month of 1945.

The scene will be based on a ruined building, with a SU-76M (that came with the kit) within the ruined building. A King Tiger of Pz.abt 509 is roaming on the street beside the ruined house. The SU-76M was trying to aim the King Tiger's tracks. Luckily the German infantry took down the SU-76M by ambusing from behind with small arms and grenades. There'll be some dead russians, and German infrantry try to inspect the wreck and to plan the next offensive action.
The SU-76M haven't started yet, but the King Tiger is under construction. (See my "King Tiger" in the In-Progess >Amour topic).
The construction of Miniart's Ruined House is more difficult than I expected, but it's kinda fun as well.... and alot of work required. My young age modeling provided me experiences but those models are crap due to lack of modeling skills. I learn modeling tricks mostly from magazines. But none have shown how to build Miniart's Buildings. Hopefully this topic, we can share our thoughts and see how to make it easier.
The following picture show a typical building part.

It's all about my Motor Tool (I use Black& Decker here, small tool but provided good torque strength.) I use the grinder disk to cut out the big pieces of plastic. It's difficult to use hobby knife coz the plastic is 1mm thick. Difficult to use mini saw coz the parts are flat.

p/s: I don't press the part to the table and cut. I do like this in the photo coz I need one hand to operate my HP camera
So... the extra plastics are removed... I keep these big chunk of plastic for future use (scratch build, reinforcement..etc)


There are some hard-to-reach areas for the grinder disk. So.... have to change to the "Big Flat Stone"..... I call it.

There are still little remaining plastics that need to remove. I don't go too precise on the above steps coz scare damaging the parts. See following picture:

Now I use a smaller version of the "Big Flat Stone" to sand and trim carefully.
For imaging purposes, I use the parts that I have done before to show the fit. After removing the horizontal plastics, there's still a 1mm extra plastic need to remove or else the parts won't fit nicely, see:

Notice the top half has been cleaned, but the bottom part haven't. You can see the extra 1mm plastics between the fit gap. So, I call in the "small flat stone" to grind it down. I use marker to color the part that need to remove so that I don't over do it.
Now the fit is abit better. Next is the job for sand paper and hobby knife. Expected some parts need putty filling.

So... all that for 1 part. Next:
