Thanks fellas, order’s going out in short order!

Website says $3,200 with a dollar sign..... I’m guessing that is in Yen...... the fact that it has a dollar sign though.....

If I put it in the shopping cart then it shows as 3,200 JPY. The comma representing units in thousand I presume. As that seems a likely price converted to euro's.

3200 yen is 25.90 euro or 29.1 dollar.

Ridiculously expensive for what it is. It should be about $20 and you'd
sell heaps of them.

Response from Consise:

I have the no. 28 and indeed it has English instructions, though I never read them. All slide rules come with similar instructions which are basically just leaflets, folded sheets of paper, with basic instructions. But you do not really need these instructions. All slide rules work pretty much the same and instructions on how to use them can be found on the internet.

The no. 27N and 28N are exactly the same, the only difference is that 27N is the Japanese versio and 28N the English. These are very basic pocket sized slide rule (diameter 8.35 cm). These do not have trigonometry scales.

For in-game use you need either the no. 270N (outside diameter 10 cm) or the no. 300 (outside diameter 11 cm). Both these have scales on both sides and include trigonometry scales. The no.300 in the most suitable to use for calculations needed in game as the C, D and trig. scales are all on the same side. The no. 270N does not have these scales on the same side so you have to flip it over while doing calculations and it requires more steps.

Attack Disk etc
 

I am trying several attempts... topost some of the photos I made regarding my attempts at making disks and templates... here are some

Hi all

Some question with regards to the RAOBF wheel.

Will the wheel work for SH3, SH4 and SH5 or does it depend on the certain mods that ensure that the tick makes on the periscope view correspond with the scale on the RAOBF.

With regards to sharpness and clarity which one ( maple or acrylic ) is the better. I ask because I was thinking of purchasing the Acrylic version but I was concerned that with use over time scuffs and scratches would develop on the underside because of the contact with the mdf backing board and this would be seen because it is clear. Would some kind of velvet backing on the mdf board help to stop this do you think.

Thanks

The size scale is based on that of Wolfpack, which are in centi-radians. Which basically means a slope of 1 meter height, by 100 meter distance is used as the unit. It would depend on the mod which scale they follow. Better ask the creator of the mod if it is (mili-)radian based, or if it is sized in terms of degrees. The former is the most common way. Otherwise you would have to make reference calculations of ships in a friendly harbor with known mastheight or length at a known distance to a dock or something. Or true map positions with map-updates enabled.

I have an acrylic version of the attack disk (course solver) wheel with a wooden back plate. The laser printed side is on the top. So mine will not immediately wear off due to rotating. But the backside might reduce the contrast to the underground if wear develops. Unfortunately I am unable to say something about wear as I have not used it much because of lack of play time the past months. A velvet or some other soft cloth would seem to be a good idea if this develops. MY RAOBF is of MDF so can't relate to that either.

Thanks for the quick reply, could you post a link to the wolfpack mod so I could read up on it.

Many thanks.

Also to the designer of these tools if you could find a way to make the german ones ie Zeit Disk and the Angriffsscheibe I would definitely throw my wallet at owning them in the same build quality

It's not a mod. It's a game, and this thread is in the forum section for it. ;)

Pices the acrylic attack disk you mentioned is it one of the versions on sale here, if so could you perhaps answer a few questions with regards to its ease of use and construction.

1. How is it built and does it hold together well with the pin

2. Do the discs move easily and hold their set position well

cheers

Because I helped Lancezh with how to make the scales for the RAOBF he sent me some test samples of the wooden RAOBF and the acrylic attack disk to check. So they are not entirely representative of the final product.

The final RAOBF has a reasonable smooth turn from the beginning. After some use it gets better by it self-abrassing the rims. I pre-empted with rubbing candle-paraffin. But I don't think it was needed in the end. Instead of the round pins he now supplies wooden pegs which stick deeper and keep it better together. I can hold it up-side-down. The spare-pegs also double as gripping tools. As your fingers won't have much grip on the holes because of their size. See message #8.

The acrylic rings of the attack disk course solver are running very smooth inside each other. In fact, because of the flat surface of the AOB disk the bearing-arm actually sticks too well to it (by vacuum suction) making them turn together when not fixed by your fingers. I don't know what Lancezh supplies now, but the plastic round pins are too short for my taste. Mine does not penetrate the back-plate far enough to hold together. Although the rings stay well centered on the back-plate when it is laying flat on a table, it comes off too easily when picking up and tilting the base plate. I intend to fix it with a countersunk metal or plastic bolt and nut when I use it extensively. The stickiness of the arm on my ring/disks may also be due to too much pressure on the plastic pin I just found out.
