- Which wheel is finer, a 60 grit or a 36 grit?arrow_forwardHello, I hope you can help me. I'm trying to create a device that has a spinning axle and I need to change the rotational force to be perpendicular to the axle. I know there are gears that can fit together have teeth, like the attached picture. I know there are other types of mechanisms, and some are more creative. But I also need for the solution to be low friction. What are 2 low friction methods of changing the directional rotation of a power axle 90 degrees? The entire creation is small, probably 12" x 12" Thanks for your help.arrow_forwardPlease I need 6-explain the use of compound gear instead of a simple gear train ( no more than 50 words)arrow_forward
