Half-frames and how to work them out!

[Haanaya]

Hello to all,

Could anyone please give me a simple run-down on how to calculate half-frames, I have 20 frames on the plan but I need to do a couple of frames in between and I am not sure the best way to get accurate frames.

Many thanks in advance.

working from the waterline draw horizontal lines above and bellow at equal distances. along these lines allways from the centreline measure the two frames that you are going between the measurement is half the difference on the new frame hope this helps you..Bill....

Hi Bill,

Many thanks, That's about what I had in mind, just thought I'd check as sometimes there's an obvious, easy genius method you miss!

Thanks again!
