Laying out at 1/8th inch line pattern.
Then score the lines with a hobby knife, this cuts the wood fibers for the next step.
I then score the cut lines with a pointed object to press the wood inwards to create a panel effect into the wood.
Now I add strips of plastic stock for the frame work. The strips are 1/8th of an inch wide.
Now I layout little squares that will be the pick up points to the containers, and with a fairly small hole punch, punch holes in the center of the squares the cut the squares out and glue in place.
Next I added the doors.
A good coat of diluted wood glue again to insure nothing falls off!
Once they are all done, I will give them a good base of primer paint and then paint the containers to the colors that I want, then weathering effects will follow.
I know that they are not super detailed but, you get the idea that they are shipping containers.
This is a very cheap way to make such shipping containers and a lot of them, the only draw back is it take time to make them, If they get lost or just plain leave the table you haven't lost a lot. just make more.
