EQ6 shim adjustment how to measure?

[ncjunk]

Hi,

I am following the guide for measuring the values off of the eq6 in order to enter them into Astro-baby´s website but am a little confused on Inches...sorry I am metric...unless you´re talking about wood in which case you can´t beat a bit of Four by Two.

I have a magical measuring stick or Vernier Caliper but don´t know how to translate the reading into the value to enter.

There are two scales on the Vernier one going from 0 - 1 (16 marks so therefore 1/16th of an inch per mark) then a smaller scale from 0-8 1/128th of an inch.

So I know I read the first scale and then the second and I get the following:-

12 (1/16ths) and 6 (1/128ths)

8 (1/16ths) and 0 (1/128ths)

6 (1/16ths) and 3 (1/128ths)

4 (1/16ths) and 7 (1/128ths)

How does that translate to the values required for ABs website?

Thanks in advance....I couldn´t bring myself to buy a digital one it just looks like it ruins an elegant and beautiful tool by sticking an LCD and bit of plastic on it!.

The first one 12 (1/16ths) and 6 (1/128ths) is calculated by

((12/16) + (6/128)) * 25.39 = 20.23265mm

or in words 12 divided by 16 plus 6 divided by 128 all multipled by 25.39 to give millimeters

substitute the rest of the values for the answers

This is specifically for the astrob baby website with shim calculator i dont think thats in mm

So i need to know what i have to enter based on the above numbers.

I can read the mm scale on it no probs.

ah ok I just looked and it needs decimal inches.

so the first one is 12 divided by 16 plus 6 divided by 128 = 0.796875"

2nd is 0.500"

3rd is 0.3984"

4th is 0.3047"

Ahhh that makes sense now, simple when you put it like that.

Thanks!
