Adding machining allowance to a 3D model

I've a project about machine tools working of a Pelton bucket. I've only knowledge of traditional machining, not CNC. Thus I thought to add allowances in the lower part of it, where occurs the connection and where there are the holes. I thought also to add machinig allowances to the superior knife and elliptical shapes. I'd like to know if you would add machining allowances in the internal elliptical shapes and over the knife of the bucket and if, in you opinion, it's possible to machine them without CNC tools.

There is an image of the bucket attached.


Thank you all
