So lets get those whiz wheel templates out

Immacolata · 03-22-07, 05:11 AM

Its the same everytime. All traces of a working whiz wheel to print out are vanished from this earth.

If anyone has stored a nice, preferably vectorized whiz wheel for printing out, now its the time to let us know

gifs and bmps and jpgs are no good, they dont scale.

Whats a whiz wheel? A slide calculator that helps you get a precise AOB very fast. Makes manual targetting loads of fun. I use a cutout paper and a calculator to make AOB readings faster.

i uploaded kim ronhof's tools to filefront, there is a bearing rate computer in one of the files, its called the course calculator, with instructions on how to make and use it.

you will need to download a demo version of deltacad, link is here

Blimey. That looks really complicated ! But its in vectorformat so thats good

Check out this thread that I started a few weeks ago. Your request will be granted there.

Since I have never been able to find this for download; I have just finished recreating Etchasketh's Bearing/AoB tool discussed in "Wazoo's Manual Charting & Targeting Tutorial [v 2.3]".

I recreated this by importing the image from the .doc file into Paintshop Pro X as a layer. I then began building layers, tracing the original components onto the new layers. The result is a very serviceable AoB wheel.

I have uploaded the file both in paintshop pro format (.pspimage) with all layers unmerged. I have also merged the base and wheel and saved each in .jpg format for those who can't access the paintshop format.

Both files can be downloaded at http://hosted.filefront.com/cdrake66/

All credit for this AoB wheel goes to Etchasketch. I simply put in the time to rebuild it and I wanted to offer it for others to enjoy.

Regards,
Chris

The other wheel (IIRC the Etchasketch wheel is the 3-ring wheel?) is still here ... http://www.spidermine.com/SHIII/wheel.swf . It's a "live" wheel on-screen, but I printed this one out and made/cut the smaller wheel from a copy, and it prints much more nicely than the 3-ring wheel.

As the autospeed finder is currently broken in the manual TDC in SH4 then i use Kim Rønhof's Course Calculator Mark 4B.

With that one you can find a pretty close match of the targets speed by:

1) turning so you have the target on bearing 90 or 270

2) estimate AOB

3) plot AOB with the marker, figure what Sin(AOB) value that is (scale d).

4) match your own speed on the inner wheel to the Sinus(AOB) scale that is the most inner one of the two.

5) Read an estimated target speed at the big triangle with the text "Speed 1" on the inner scale.

Fast and more precise then what els i can come up with. It is ofcourse more precise to plot a couple of plots and read it off that, but sometimes you just dont have the time to plot.....

Nico71 · 03-30-07, 02:27 PM

Re Kim Rønhof's range finder, do the tickmarks and ranges still apply in SH4 or do they only work for SH1?

Is it possible to get it to work with SH3 as well? I have no idea how to make such dials and slide rules with CAD software.

03-30-07, 07:12 PM

If masthead height is read from a correct source and you use the periscope zoom level that are on the wheel - yes it works in SH4 as well (it would even work on a real sub)

But if the zoom level in SH4 differs from the wheel (i cant remember that right now) then it will not work for anything but x1 zoom.

Crosseye76 · 03-31-07, 02:42 PM

Good info.

jmr · 04-08-07, 04:50 PM

Anyone want to share pictures of their completed Kim Rønhof's plotter?

jdski · 04-08-07, 06:21 PM

I just saw this one today.

Could you tell me what the outer numbers (on the L-a ring) are on Kim's Mark3b range calculator? Do they represent the periscope graduations?

04-09-07, 03:01 AM

Yea - as far as i understand it.

The outer L-a ring are periscope tics, where the decimals are the small divisions and the large divisions represented by 1, 2, 3, 4, 5 and 6

Next you have the B Scale (or L-b) that are masthead height on the ship you have ID'ed. Lets say a Kongo Class Battleship with a masthead height of 141 feet.

Say it covers one large and one small tick in the scope - giving 1.2 ticks.

Now turn the wheel so 141 is next to 1.2, then at the 2.0 mark (black triangle) you read the distance at the appropriate scale (C, D, E or F) depending on the zoom level. Currently im only using the x1 scale (C) as its unclear what zoom level the attack periscope is using. - In this case setting the Kongo at 1900 yards.

So :

OMH - Observed height in ticks on scope
MHH - Actual height of mast in feet
Allign OMH and MHH and read distance in yards next to 2.0 on the correct zoom scale.

Is it possible for you to give step by step instruction on how to use Kim Ronhof's calculator Mark 4B? Maybe have some figures and which wheel to turn. Thanks for the instruction on the mark 3B.
