Here are some pictures to explain what I tried to do. I am sad to say that I would have to laminate the printed transparency more than 4 times. The thickness of laminating that many times would prove problematic due to bubbling and separation tendencies of the material.
Here is the sheet before I laminated it a second time.
As you can see, the printed transparency is pre-laminated.
More detail of the un-laminated transparency.
Here is the second lamination that thickened it by .35 mm.
The part is now a little bit thicker.
Finished piece that is not slotted.
A closer look of the side piece.
Mark 5's conning tower.
Here is where I found out that this was not a good idea.
It was flimsy and floppy.
I didn't bother slotting the tread units. I may come back to this
but I got frustrated and now this resides in the trash...
