that's a good idea.
Bellow is a re-post of Spheric's comments on build accuracy:

Spherics's answer to question:April 2008
I'm away on a course so this is a quick reply. With pulses although we talk of a phase shift we are talking of the time between the start of one pulse and the start of the next pulse as being the same between each successive pulse, in an ideal world. If you are using the same type of drive components and type of mosfets, have high tolerance resistors and capacitors, and keep wire lengths between components as short as possible but consistent between each driver circuit, mitigating impedance and capacitance effects of the wires, the delays to all three coils should be almost identical. So even if there is 50 nanosecond delay, if it's the same delay to each coil then it's not a problem. Even a difference of 10-30 nanoseconds between coils will not dissappoint in terms of output energy and cold elec effects.
Let's take a typical poor-build. Each coil has different widths out by 1/8inch or more. The coils are wrapped until either the spool is empty or it just seems the right height. The length of wire between coils varies by 15-20% at least. These coils will require independant delays of hundreds of nanoseconds and increases in pulse width of hundreds of nanoseconds to get a *consistent* output. But even without adjustment they'll get output, however the amplitude of that output will come in waves and not be as high as it could be, and the amount of input energy used will be much higher due to the much longer pulse widths. They will be unlikely to get a consistent cold energy output, the lightbulbs in the SEP circuit, may ebb and glow slightly. It may or may not be overunity but possibly only by 10%. All exciting stuff but it's not a setup that is going anywhere. It is not really utilising any flow of cold electricity, just bursts here and there. i.e. because the pattern is not building up, it is occuring only in waves, and is relatively feable, i.e. there is no 'resonance' in the ether.
In answer to your question if you build your coils carefully and locate them precisely and rigidly, I would not bother with the delay line components. At a later date for reference:
These are useful for pulse width:
