That sounds big! Off the top of my head 1mm = 0.040" (close enough for Horseshoes....and "Old Ladies"! : )

The 1 to 2 ratio makes sense for a true Hex,
the top 1/4 = 1/2 0f the length of one side,
as does the bottom 1/4.
This with the top and bottom angles at 45 degrees.

Simple enough! I just like to see how things work.

I guess that my fuzzy math effectively shut down this thread....Or just maybe your generosity let me slide on my fuzzy math....Or were you just standing back and scratching while mumbling "Forty-Five Degrees! What in the HELL is he talking about?"

45 degrees works if you want what some of us refer to as a Lozenge or polygon, but not a hexagon!

I was thinking about this and it bothered me, so I drew a crude sketch and saw my error. Six sides of equal length: slice a pie into six equal segments and each one will be 60 degrees (60 x 6 = 360 degrees). Each side of the hexagon to the next will be 60 degrees around the perimeter, six points, six times. Depending on which axis you work from you will either have a 60 or 30 degree angle.

Silly me, I am afraid that I simplified it to the point of me being "Simple Minded" the first time.

I am going to go crawl back into my cave for a little while.

Thank God this wasn't so severe that I had to take myself out to the shed this time!

See Ya, Jay

Being math challenged myself, your original formula for a polygon seemed to work for me on a hexagon. Don't beat yourself up too bad, you did manage to catch it and share it, so come out of your cave and enjoy the light of another day: Albeit here in Wisconsin where we are anxiously waiting for spring we are anxiously awaiting a 12" dumping of wet heavy snow. Good day to stay in and tackle a model.

Gentlemen:
Let us not make this complicated.
1. Prior to April 1917, the German Navy to my knowledge had no specific Sea Camouflage Scheme for aircraft. Probably stipulated in the contract some moistproof finish.
2. The German Navy issued a new paintedcamouflage scheme. 300mm in diameterin true hexagons (six sided figure)in blue-grey, blue-violet and blue-brown. these hexagons were to be painted the the tops of the wings, upper and lower, tailplane, fuselage and the floats.
The sides of the fuselage, fin, floats and all struts were to be painted grey-blue. The bottoms of the tailplane, fuselage and floats were to painted light grey.
3. The bottoms of the wings and tailplane were to be clear doped and waterproofed linen fabric.
Blue skies,

Gentlemen:
1. In April 1918, the German Naval three color printed hexagon fabric was introduced.
2. The printed colors were grey-blue, grey-violet and grey-brown. Those were the only color ever used.
3. The irregular hexagons were actually, six sided rhomboids, were 200m in height, 155mm wide and slanted 5 degrees to the right, in the warp yarn direction. The sides of the rhomboids were 100mm high.
4 The three coor printed fabric was to applied to the tops of th upper and lower wings, tops of the tailplane, fuselage and floats.
The sides of the fin, fuselage, floats and all struts were to be painted grey-blue.
The undersides of the wings, tailplane, fuslage and floats were to be painted light grey. The under sides of the wings and tailplane maybe clear doped and waterproofed natrual fabric.
5. This was the only scheme used, there was no other colors used and there was no other printed fabric colors.
Blue skies,
Dan-San

Thank you Dan-San, that is exactly what we needed here and the first description ("Hand Painted") is also very straight forward. I can see the Rhomboids ("3. The irregular hexagons were actually, six sided rhomboids, were 200m in height, 155mm wide and slanted 5 degrees to the right, in the warp yarn direction. The sides of the rhomboids were 100mm high."). Thank you for the clarification.

We do appreciate your expert attention to this matter.

Thanks again, Jay
