AoB Calculator based on CapnScurys Realism Tutorial
 

Hi I am releasing my printable AoB calculator based on the excellent Tutorial and AoB Calculator by CapnScurvy http://www.subsim.com/radioroom/show....php?t=150069.

These can be printed out and laminated to make them stiff, or in my case printed onto transparencies and glued onto perspex or plastic. :DL

Is-Was Calculator released 10/07/09

Ok have finally got around to completing a version based on the original Is-was Calculator, in a similar scheme to the AoB calculator in the first post.
Layers C and P have to be printed on Transparent material, A & B can be printed on Photopaper or similiar.

Can be downloaded from:

Thanks a lot, Reaper7:up:

It's very nice, but what's the comparative advantage of this design over this replica of the historical tool here which includes a periscope overlay?

(in this picture the front and back sides are shown as separate entities, but normally they are all one - the back side is a speed omnimeter for solving speed using the collision course method)

Nicolas' Easy AoB mod
 

Nicolas' Easy AoB mod, see post in SH4 Mod Workshop, may eliminate all the paperwork. It is easy, simple and IT WORKS. I have successfully made shots of over 4,000 yds. at steep angles, and hit targets at night with poor visibility.

It has my vote for mod of the year. Once you can handle this mod, you have probably outgrown some of Rockin' Robbins and Werner Sobe's attack tutorials. See my posts under the Easy AoB mod by Nicolas.

Per request and another in the bag of tricks to sink the big ones....stickied. :03: Annnnnnddddd.....I will try this out later:D Cool:yeah:

AVG Warhawk's post
 

I believe you intended to say that you were going to sticky the Easy AoB mod, but your post was ambiguous, as it was in the thread re CptnScurvy. I think that is what you meant.

YOU WILL LOVE THE MOD. The SS Barbarinna is now dangerous!!

Good call re the sticky suggestion! This mod changes the game where it matters---sinking enemy ships.

Well, no, looking at this it can stay. Some might like using this and viewing the tutorial.

I need to look at the other thread you speak of.

Hi joegrundman, I don't know of any advantages this calculator has over the original Is-Was one used, As I haven't tried one yet - I Use CapnScurvys method that is linked in the top post but wanted one with more resolution than his posted one.
If you see my second post I am working on creating a replica Is-Was calculator not necessarily based on the original but to match the styling of the AoB Calculator.

Just to show the results of using Perspex - This will last indefenitly. (Maybe time to try one using Brass - Sweet)

I see, yes good luck with that. There is no doubt that the finished beast you have made is a beautiful thing:up:

Functionally, they are identical. However, his has cool colors and your WWII (or shortly thereafter) model is lacking in that regard. However, Joe's appears to be waterproof and yours doesn't look sufficiently marine quality.

I'll go for the colors! It'll never get wet on a submarine, will it?:D

They are not actually functionally identical

They are if you don't look at the back side of yours! I never look at the back side myself.:D

There are some minor details on how you use the front side but they serve identical functions. Switching from one to the other would be painless and almost instinctive.

where can I buy one
 

how about sending me one of the AoB calculators?! The one on the desk was quite cool. If it were weatherbeaten, I would build a replica sub, put it in my pool, and use it on missions. I likes it.

Wow, reaper7, how did you make that?

How to Build
 

Actually quite easy to Make.
First print out the 3 layers onto either sticky backed photo paper or standard photo paper if want to glue it.
Cut out and stick to approx 5mm plastic sheet, rough cut out the disc's and base layer.
Now to create perfect circular disc's the method I used was to fix an Electric Disc Sander at right angled to a Table top with clamps.
This allowed me sand down all the items to shape using both hand to work the pieces.
Then drill out the center holes and place a washer between each disc and secure with a bolt and nut. Finished.

Hope this is of use. :yeah:

Excellent work Reaper7!! I like the idea of putting the dials on a sticky backed photo paper, then putting them on a hard surface (like plexiglass) to hold them together. I found with continued use the hard stock paper would oval out at the center hole and allow the dials to move a bit. Your graphics are superior. Thanks for making a hand made calculator a desk top necessity!!


Well for one thing, the AoB Calculator has individual degree marks for precise measurement. This allows for a more accurate map plot of a target when disabling the map option for showing a targets position. With a precise target heading (and target range) Angle on Bow will be found, completing the firing solution (short of speed estimation).

I'll be honest with you, their quite similar. But believe me, I hadn't even seen the original Is-was (or whatever you want to call it) untill after I introduced mine. I guess necessity breeds ideas no matter what the decade. My first design of a three dial calculator (1. Subs Relative Bearing, 2. Compass Bearing, 3. AoB Bearing) came from a two dial calculator introduced by a fellow named Wazoo during the early Silent Hunter III days. Wazoo had a great tutorial for manually finding range with the U-Boats which I cut my teeth on. I figured by adding the subs relative bearing (the bearing seen along the top of the periscopes image or TBT) a better calculator for finding a targets position and heading could be made. I worked on the dials during the winter of '06-'07, cutting and pasting (no really I used Elmers glue to paste "Word" numerals and compass descriptions onto a dial; used Photo Shop to clean up the glue mess), then figured out how to get my feet wet in posting in a forum I'd only been a long time reader of. Up to that point, I hadn't figured out how to use the Position Keeper yet. I may not have made the Calculator at all since the Position Keeper does a great job of calculating a targets heading and true north bearing. Anyway, the tool is extremely useful for the German side of play; and convenient for the American side to use when at the map station plotting a targets bearing and heading.

Hi Guys, I have posted my version of the Is-Was calculator.
Download link can be found in post 2.:DL:DL:DL
Enjoy.

i do not have the tools
 

Gardening tools I have. Electric tools I do not have. I bid $25 plus shipping, Captain Reaper, sir, for a finished product.

Reaper7 those look awesome. :up:



I wish I could build one, but nope. :-?
