I have recently been faced with a similar problem deciding the size of nuts bolts and studs to use on the 1/12 scale extrusion press that I am making.

On my CAD system I drew up the BA range 14BA to OBA at 1:1 then scaled them by times 12. Using these on the 1:1 drawing of the press, when I divided this 1:1 drawing by 12 I then had the correct looking BA fixings for the model.

see http://www.boscott.co.uk for more details
