RE: How to build an accurate model of small part without using formers
Whether you realize it or not, I gave you the answer to your question, in my previous post.
I've guided you about as far as I can, down the dimly-lit corridors of your own imagination.
Most inventors restrict their inventions to the materials and processes that they have intimate knowledge of, and when they need more information, they get it through careful expansion of their own abilities. (trial and error)
If you cannot divulge even the basic shape of your 'invention', since you think someone on this forum would take it from you, why do you think that any of us should part with our information, that was gained at an even higher price, than an afternoon of daydreaming, as must be in your case?
I'll have to go with Mike James on this one, Sanghera. Stop pondering and start some practical building. Who cares if you build more than one prototype? All you have is time, anyway!
