--- Quote from: 75Plus on January 26, 2014, 11:29:00 AM ---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 --- End quote --- Good idea Joe! :thumbup: Not much clearance on the shaft for a pulley. What sort of revs would it need? :scratch: David D |

You will start getting voltage with as little as 10 RPM. Depending on the design voltage they can go up quite a bit more. The polarity will change depending on the direction of rotation. |

Thanks Joe. Something to keep in mind, for later....... :thumbup: I've been "watching paint (and varnish) dry", most of last week. While life got in the way, the rest of the time. :( Puzzling how to make the flywheels, Mia manageable. I remembered, she had included the 1.5mm allen key, as part of the game. Hmmmm. This bit goes here, somewhere........ So, I drilled n tapped the half shafts M5. She can have a couple of capheads and washers to play with! The alloy hubs will be sleevelocked onto the half shafts, then the flywheels bored to suit. Looking a little more respectable, I think...... David D |

Hi David Lovely intro into engineering for Mia. :clap: :clap: As an aside, I noticed your tailstock arrangement for the rotary table on the mill, I have a similar RT (Soba 4") & was looking at getting a tailstock to match from the usual supplier but have not noticed anything that bears resemblance to your set up, seems to be sitting on a tapered rising block ? is it home made or do you have any ref / link to it... drawings maybe? regards George. |
