Thanks Chris! I also made one of those little rockers. It was strobed at 9,000 rpm at 40psi. But, I have never tried it on gob power. Yet. Bob. It's surprising, just how long females can hold a grudge! Hoping Mia can't see through the camouflage I'm planning. Thanks Eric. I certainly hope so! Time to make the two cranks. This is the first time I've made anything from mild steel! En1a? I have always used heat treating steel, when at work, and since retiring. En24/ 36/ 39/ aisi4140 etc. But, stocks are now getting low. I've had to buy some. Got to admit, it's sweet cutting material....... Drilled/ reamed 1/4" through, from either end. Part off....... 4mm dia, drill/ ream, the 6mm throw....... Drill/ tap, the grubscrew holes........ Finished....... Spun in the lathe chuck. One end is within 2 thou of the other....... Crank assembly finished....... Finger clearance, under the lever. Now need to make a knob, or dish to mount on top ........ Flywheels, next. Wooden ones! :thumbup: David D |
| Stilldrillin:
Flywheel time! Two blanks, chopped out of a 16mm chopping board. 1/4" hole through centre........ Mount onto 1/4" bar held in chuck. Friction turn against chuck jaws....... Cleaned up at 4.3" o/d. That will do, for now........ Test video........ Need now, to design some detachable hubs. For when Mia Mechanic wants to play. David D |

David, Those tiny PM motors that are used in toys make excellent generators. Perhaps you can find one small enough to hide inside the motor and use it to power a lamp bulb or LED's when Mia is running it. Joe |
