Great job on the ambulance, I think I'd like to try it myself, I take it you bent the roof, what's your tip on doing that?

Hi Ray,
I like your spirit. You'll find this is straight forward project.
To start, you'll need to measure the extreme limits of the cargo box of your model, so you can establish the inside size of the van body. You are looking to obtain a snug fit. I made a cardboard mock up before I commited to plastic.
I like to use 1mm (0.040") thick polystyrene , because you can cut it easily by scoring it with a knife and bending it.
The key is to make an egg-crate structure that sits atop the original cargo box. This gives the body the strength it needs. The cross members of the egg-crate will all have the curvature of the roof on them. When you do this, make a template to transfer the curvature, because you want them to be all the same.
After the the egg-crate structure is dry, carefully glue the sides and end panels to it. NOTE: You're going to have to carve away some of the plastic on the inside of the side panels where they touch the shovel and pick-axe that are on the original box. If you don't do this, the van body will bulge out in these areas. It will ruin the appearance. This may require a little work, but it'll be worth it.
The roof is just 0.5mm (0.020") thick, so it is easy to bend by hand to form a rough curvature. When it's glued to the egg-crating, it easily holds its shape. After it's dry, take some 1mm x 1mm strip styrene and glue it to the edgeof the roof overhang. This gives the appearance of a much thicker roof. When dry, sand to eliminate the seam.
Once you have the basic box completed, you can add the doors, windows and hinges with stryene strip.
Front panel - 0.5mm (0.020")
Side and Back Panels - 1.0mm (0.040")
Egg-crate - 1.0mm (0.040")
Roof - 0.5mm (0.020")
Top Roof Panel - 1.5mm (0.060")
I've attached a picture of the plan I drew before starting the project. I hope this helps.
Good luck with your project. I look forward to seeing the results.
Regards,
Wayne
