Basics
- Need 45000 in lb or 510 kg m force for basic helical pile driver
- Use a standard 5" sprocket with 3" hex shaft - but 10x the meat in plastic.
- Sprockets can be CNC cut out of 1/2" steel at low cost
- Then belt is the only 'expensive' part for 1/2" 'meat' belt that is 5" wide.
- Calculations show 45000 in lb strength of such a belt, with 2x safety factor.
