imperial system stairs

[ska7979]

Bye to all,
I happen, at this time, for the first time having to work on drawings in inches.
My fundamental problem is now the following:
When I untie the drawings I obviously have to refer to the stairs used in the imperial system, then, starting from the drawings of the customer, I used the following stairs:
- 1-1/2"=1-0 (1:8)
- 3/4"=1'-0 (1:16 approx.)
- 6"=1"-0 (1:2)

And all right here.
Now to fly some parts I would need to move to a less detailed scale, but I do not know which ones are normally used in that system.

Does anyone have any experience in this matter?

Thank you.

Thank you very much, I couldn't find.
in the table according to me however they have mistaken the 6'=1'-0 that has a ratio 1:2, not 1:6.
Anyway thank you, now at least I have references to fly these cursed designs.
