 11 Jun 2014 06:20 PM I am not an engineer. I am a mechanic by trade. So forgive me if this question is stupid or unreasonable. I have an idea... And invention I would like to try and build... And if such a thing was possible... It could literally change the world. Is it possible to design a gear box or a transmission in which the input to the transmission was 700rpm max @215 ft/lbs of torque and the output being at or very close to 3600rpm @ 35 ft/lbs of torque. I have literally no knowledge on how to figure something like this out or where to find answers. Its just a crazy idea I came up with... And f designing a transmission such as this was possible... My invention could actually work. And without saying what it is... It something that I cannot believe a guy like me could invent. And idea you would've expected someone would have already thought of and tried to make work. Anyways... Let me hear any POSITIVE input anyone has to say.
