Hi there. I am working on reverse engineering a an assembly drawing into CAD. This part has a couple bends and a call out that I have never seen. Anyone know what this is telling me? images attached.

is it the slope of the joggle ? 0.08" in 0.48" makes sense; "14 in 84" not so much !???

another day in paradise, or is paradise one day closer ?

Yeah. Lots of older stuff was done like that. I spend a lot of time updating prints from the late 30's to the late 60's.

14 in 84 means... 14inch rise over an 84inch rise... assuming those are inches. They probably had a machine or jig with a base of 84. See it a lot for lathe turned parts based on 12"

So trig it... tan^-1(14/84)=9.462 degrees.

Also looks like it only applies to items 69 and 85

See attached pic... looks close enough.

Thank you so much! @RoarkS very helpful. Yes this drawing was made in 1957.
