Talk:Cold Saw/Build Instructions/Fabricability Review

I like the work from YK on the saw. Regarding drawings, I would like to add some comments:

Rendering with threads: [[1]]

And I did a drawing in accordance to metric ISO standards: [[2]]

- in ISO tolerances aren't specified by the number of digits, thus 10 and 10.000 are identical in precision. Standard is to omitt trailing zeroes.

- metric standard threads are written as "M 12", not as "M 12x1.75". Latter designation is only used for metric fine threads, ie. M12x1

- its standard to apply a diameter sign only when its not visible as round. If the dimension is attached to a circle, no Ø is used.

- I am not happy with the method for dimensioning diameters. In my drawing its the standard method; YKs version is an exception.

- I confused about some dimensions in those drawings. Why are there values like 31.8 and 51.8 mm ? Why not 50.8mm (2") or round 50mm ?

- In the drawing header there are dimensions specified. This is not common in ISO. Also these tolerances are obviously nonsense. Don't think, YK wants us to drill a 12.700mm hole with a tolerance of +-0.005mm????

-drill bit size for M 12 is 10.2mm, not 10.5 . metric diameter minus thread = drill bit size
