Best way to figure out motors and gear reductions

[modelman]

9w is correct but he is a professional machinist and doing things like tapered drums was way above my skill level. My shovel model was small so I too had small drums but I used 3/32" black nylon rope and it would wrap good and stay in the grooves on the drums even with no load. Depending on how accurate you want to stay to scale you might want to consider this. I tried wire rope on my shovel and it would not work. If you click on my user name and get my public profile there are build pictures of my Marion 182M shovel. May be some things that will help-not sure. Good luck
