Re: Robo3687's IRON MAN Mark 4/6 Pepakura FOAM Templates -Easy to Build "Green" Versi
...
I used 4mm & 6mm for most of the build. Then 1/2 inch for the chest and back...
I wish I used 6mm for the entire build because all the 4mm pieces ended up tearing.
+1 on the 6mm foam for most of the suit. Chest, Back, Arms and Legs, and Helmet. I stuck with 6mm for the chest because I had a lot of electronics mounted in that section that needed the depth.
a. PA system with serious volume
b. wireless microphone receiver so I did not have wires to the helmet
c. EL lighting driver and associated batteries
I will recommend 3mm for the abs to keep it tight and so you dont look fat. I deviated from the design files for the abs. I started with two large 12x17" 3mm sheets, one for the front and one for the back. Then cut out the panels per the design files in 3mm and glued them on the sheets. This gives the detail needed but keeps it super thin. Then after last fitment before paint, I cut off the excess 3mm back sheet. Made for a great fit and it was thin.
Also 3mm for the cuffs, neck, inner detail and some outer detail.
2mm or 3mm comes in handy for internal bracing, I call it strapping, on the 6mm at high stress seams, like the feet openings, inside of helmet, etc, where you need some additional strength, but you dont want extra thickness.
