Finger Treadle

grabcad

This is a good old machinist gift, or class project that has been around for quite awhile. These are fun and addictive to have on a desk for people to play with. I made most of the flywheel hollow except the rim, so that it can be printed solid to help with the flywheel effect. The rest should be fine with your normal settings. During assembly the closed holes should be pressed in( or drilled out and glued in) BE AWARE I have not printed this so the shaft holes may need to be adjusted, some are free fit and others are light press fit. Make: 2 - Flywheels (print with high fill to add weight at the rim) 2 - Links 1 - Base 1 - Treadle 1/8" shafts: 1 - 0.9" 1 - 1.6" 1 - 2 1/8"
