Made myself an "is-was" yesterday using the great stuff from the Cap'n and Hitman and the advice of others contained in teh posts here. Used laminated cardstock for first three layers of the front side and the bottom two layers of the back side. Cut up the plastic overlay layer from an old poster frame for the transparent layers. Printed the periscope and 'time in minutes' layers on clear stickers, adhered them to the thin plastic and then laminated them as well.

Carfully lined everything up, put the holes in and assembled with a short nut and bolt forming the spindle/axis. Happy with the alignment, I disassembled. Cut a piece of foam poster board as a backing material, then glued the base layers of the front side to that and made a hole for the bolt. Trimmed the poster board to fit, aligned and glued the back side base to the poster board. Reassembled and put into action.

Pulled into Surabaya on Jan 2, 1942 and earned my first RFB 100% realism Silver Star.

Coincidence? I think not.

Only 'mistake' I made was failing to heed the advice of others and put a proper 'handle' on the 'enemy vessel' card to get around the issue of that card being the same size as teh scope. Easy enough to fix if I feel the need. Adding the posterboard 'sandwich' layer really gave the thing a tiny bit of heft and a good deal of sturdiness. Also, with the thicker middle layer, I'm able to use one of those spring type paper clips as a sort of clamp to keep the B layer 'locked in' so that it doesn't want to move around when I move the enemy or periscope layers.

Thanks again guys for the guidance and inspiration. For anybody wanting to take the plunge and make one of these, it's really pretty easy, and it's a satisfying little project to complete.

Question:

Can anybody better explain the use of the squares on the enemy card and ticks on the periscope card. I think I 'got' the first answer in the doumentation, but I'm having a hard time seeing exaclty how these things work. I'm pretty good at graphical plotting anyway, but I'd like to know more about how this thing works.
