Whiz Wheel links seem dead - where can I find a printable template?

[Immacolata]

I want to try printing out my own whiz wheel for speedy calculation of AOB. I read several threads with printable AOB whiz wheel you can cut out and staple together. But the links are dead. Anyone got a fresh link?

[SteamWake]

Hes right the link is 404.

In the meantime here is a very helpful thread for you to browse.

There are no one who knows of a printable whiz wheel template? I really wish my AOB'ing went a bit faster and I think only a whiz wheel can solve that problem for me.

[CybaGirl]

I might have that whiz wheel archived somewhere.. I will have a look for you and see if I can find it :).

If I can find it will post another reply here with a link in which you can get it from :).

[CybaGirl]

Ok I think I found it after going through my hard drives :).

Here is an image of what I have.

As you can see there is a compass at the top which you cut out and another part at the bottom that you attach the compass to via one of those.. Hmmm metal do hicky pins.

BTW the whole thing is there. Its just I couldnt get it all on screen for you.

But if this is what you are after you can download it from here.

Anyway hope this is what you are after :).

Thats not it however?

bump somone have to be in possession of the whiz wheel template?

I could enlarge and fix this copy for you. I won't be pretty but it will see you through until someone posts the original.

[TarJak]

Immacolata,

I found it on my PC and have uploaded it to filefront: http://files.filefront.com//;5980786;;/ (http://files.filefront.com//;5980786;;/)

Cavalier888 deserves all the credit for the work. I hope he doesn't mind me posting it there for others to see. I think I got it from U-boot.RealSimulation whose download database is not operational at the moment.

[Immacolata]

I guess its a start. I wonder if he was unable to find any LOWER resolution than this pixelated horror. I saw a really snazzy flash version at some point. I wonder why such things are allowed to disappear. Oh well. Ive printed them however and now I must learn how they work. Thanks for your help, they should save me precious seconds when calculating AOB.


Danlisa I dont think it will work. You need the three pieces separate and printed out then you pin them on top of each other.

This is the only one I've seen. I recall using a much better one than this when I was playing the original SH, but that was another machine which is on the scrap heap now.

There is a tutorial .doc file in the zip. It's pretty straightforward.

[danlisa]

@ Immacolata

3 x selection circles, 3 x cut to separate layers. Create a new document. Drag + drop 3 x layers into new document.

This can be done easily with Photoshop:know:

However, I won't be able to do much about the red line.

[Immacolata]

Yeah I read the tutorial. Seems okay. I just wonder why - on subsim all places of the world - that a really useful thing like the whiz wheel, can disappear into nothingness! And that the only example anyone can find is a 6 year old project that looks like it was made in MS Paint. Sigh. But it seems to work. I just need some cardboard to tack the two wheels on.

How do all the hardcore sh3 players do their AOB? Use the protractor I guess. But it is so inaccurate, you have a few seconds to enter your AOB using the horrible method of SH3, and the data is already then inaccurate.

Danlisa, do you think this wheel works better than the other two wheels? Never mind the red line.

[TarJak]

Dunno where it got to. I was pretty surprised as when I got SHIII I looked high and low for my trusty old SH1 wheel but couldn't find it. This was the best I could find and right now I use it for my AOB calcs. Not easy in "redlight" conditions as the images are not too flash. I tried using the protractor and it just doesn't cut it as the mouse doesn't give you the accuracy you need.

[Immacolata]

Ok tarjak, but I just dont understand why you need 2 wheels. The one danlisa links to is just one?

I noticed in another thread that Redwine has made a pack of pdfs that can be printed. But the rapidshare link he put them at disappeared.

[danlisa]

Danlisa, do you think this wheel works better than the other two wheels? Never mind the red line.

The only issue with this wheel is that the outer ring doesn't have any degree segments so a little guess work is involved.

Just looked at this again,
http://i4.photobucket.com/albums/y136/wazooda/67bearingtext.jpg
are you sure it should be 3 wheels?

Quote from image "Align 0 with target course bearing on middle dial. Bearing to target on inner dial indicates AoB on outer dial"

Does this mean once you have input the targets course, the bearing shown in your scope, while looking at the target, (say 050 degrees) means that the AoB is 160 ish starboard. If you go by the picture above.

[TarJak]

The 2 wheels are for course and speed. One wheel gives the AOB the 2nd is a slide rule to convert timed observations into speed and vice versa.

There is a flash wheel at: http://www.spidermine.com/SHIII/wheel.swf
Dunno if this helps any It certainly looks better, but I think you'd struggle to use it with the time you usually have and as it's not integrated it would be a pain in the backside to keep flipping to whenever you wanted to do the calc.

[Immacolata]

I am not sure, because we have no original files to experiment with.

The whiz wheel should take your own bearing to target, that is, the angle revelaed by the periscope when you lock on the target.

The whiz wheel should also have a dial for the targets compass course. The difference between targets course and your bearing to target somehow makes up the AOB. lets say

Target travels at 270 (west). Your bearing is 0 to north. a perfect angular shot. If you subtact 360 from 270 you end up with -90. If you subtract 90 from 270 you end up with 180. The aob should be -90 for this shot or 180 if you want.

Let us imagine the ship travels the other way, from NY to London it has a course of 90 compass.

You look at the ship from bearing 5 and your own course is 180.

To me it looks like AOB on this scenario that the ship is not yet passed your perfect 90 angle shot. Your AOB in this moment should then be -95 or 175?

To me it looks like you also need compass directions on the whiz wheel because AOB is dependent on your own compass orientation as well.

[edit] hey thanks for the link. I now can see it. In my 2nd example the AOB to target is -95 indeed. The problem with this 2 dial wheel is that the outer wheel lacks marks for each degree. But I wonder why some wheels have 3 dials then? What is the last dial used for calculating?

Quite right hence the need for 3 discs on the AOB whiz wheel.

[Immacolata]

But on this flash aob wheel only the inner circle moves. Crikey

:damn:

I am 13 years out of my advanced trigonometry and maths. And I never took navigation classes :rotfl: My head cannot comprehend this entirely but if this flash wheel works fine I guess there is no reason to be carried away. Now if someone would make a flash version with keyboard input I would be happy. Just type what bearing you are at and presto.


It isn't overly handly this wheel as flash, because you need two computers really. But a printable one might work fine.

[edit]

I managed to print it out. I first had to screencapture and paste the image into a program and increase resolution to about 140 dpi. It doesn't look very sharp on a monochrome laser printer though :(

[danlisa]

Lets see If I have this right (using flash wheel)....

Your targets course = 020
Set inner dial = 0 lined up to 020
Get target bearing through scope = 080 (on your current heading)
This means targets AoB = 120 Port

If YOU then change course but target does not....
Target course = 020
Target bearing through scope = 060
AoB = 140 Port

So this wheel should take into accout your bearing changes.

Am I Right?????

[Immacolata]

Your course is irrelevant as long as you just make sure to read the bearing (inner circle). AOB is merely the angle between your observation point, the ship and its traveling direction. You could turn around on the spot and the AOB would not change.

This wheel is rather good for SH3 because you can normally figure out the ships course in order to find its speed. Once you know the course you just turn your wheel so that 0 is at the ships course. Then you just need to look at the dial to get your AOB at any time as long as the ship does not change course. Very fast compared to using the protractor on the map screen.

[SteamWake]

I had the templates for this wheel at one time.

It may be still lurking on my hard drive at home and will look for it.

Failing that I can probably create one in autocad in a matter of miniutes :up:

Ill bump this again if I find it.

[Redwine]

Check PM .... :up:

[SubConscious]

Check PM .... :up:

Can you post these someplace for the good of the community? I'd bet that many people would love to have a copy (myself included, of course ;) )

Many thanks!

[CybaGirl]

Thanks for supplying this and thanks to Cavalier889 for originally creating it :).

I have uploaded it to my website so anyone who wants the Wiz Wheel in the future will be able to download it from there.

Sure... here you have.

There are another slider rulers included, for range calculation and for target relative course calculation using 3 bearing inputs, plus a version of the Whiz Wheel i made to introduce it into SH2, with 3 wheels and one cursor all four movables with the mouse. This mod has teh ruler in gray background and with two marks to be used in meters or in yards for SH1 and sure for SH4 in the future.

You can use the graphics into this mod to print a paper ruler.

Thanks to all who helped. I know have a printed whiz wheel tacked onto an old cigarbox lying on my computer table hehe. It works. It is pretty low res and smudged due to me having a monochrome printer. So if anyone feels like firing up their CAD program to make a vector model, please do :)


But I was wrong in how it works. Here is the correct method.

Find the targets course. Move the inner wheel so that 0 on inner wheel aligns with the target course on middle ring. From this point on you do not move the wheels again. Now you need to know your own course. You then add your course to the bearing to target shown in your periscope. If that number is greater than 360, you subtract 360.

Then you check this result on the inner ring and then look at the number written across on the outer ring to reveal the target AOB.

The good thing is that you can always just ad one or subtract numbers in your head if the bearing to target changes as it moves past you. It sounds tricky, but once you are good with the whiz wheel you become really good at lining up shots fast.

Last night I really had a blast (literally) chasing a convoy. I managed to damage 2 and sink 4 ships with NYGM 2.2 even! my shots were very precise and one attack had me hitting 3 ships. Unfortunately the large tanker just limped along on fire and never sank. And I was out of eels. Best patrol Ive had ever since installing NYGM.
