If you have an inventive mind ( I don't ! ) Bezoar I'm guessing a major challenge for you may be settling on a design and not permitting yourself to be distractedby too many options which may occur as you go along. twhite510 has made a truly amazing offer abovr, and he has the skills set to comprehend and grasp your design concepts. My own ( unasked for ) suggestion would be to consider sticking to GEM type blades as these are what the vast majority of UK SE users use, being inexpensive, satisfactory performance and very readily available. The adjustable facility would certainly make a new SE both desireable and distinctive. However, your concept, your brains, you get to decide.
