Turntables for Small Hand-Operated Cranes
Built by David Smithers in June 2013
3/8” steel balls sandwiched between a 2” sprocket wheel and a road wheel (metal), suitably mounted.
- Six ¾" flanged wheels on a spider made from 1¼" bolts suitably fixed on bent strips, sandwiched between two 3” pulleys. The flanges of the flanged wheels being outside the 3” pulleys mean that it is self-centring, and no central pivot is needed.
