Just thought I'd share:
Parts are printed, but are rotating on pressed in plain bearings. ![]() ![]() ![]() |

That is pretty cool! How do you handle the shut off on reverse rotation?

Do I understand correctly...a roller contact not a sliding wiper?
Genius. No friction or parts that wear out. |

Love it when members continue to ONE UP the factory part and make it simple (IMG:style_emoticons/default/first.gif)

That is pretty cool! How do you handle the shut off on reverse rotation? The roller contact is Mill-Max 0945-0-15-20-09-14-11-0. Like OEM, the primary means of preventing reverse rotation contact is gravity and inertia. Between the 2 arms are magnets placed same polarity facing each other. This provides opposing force for roller contact and are offset to prevent any contact during reverse rotation. I wish I could publish some fancy calculation to determine the optimum magnet offset, but it was trial and error until I could get something that worked reliably. Not to hard with inexpensive rapid prototyping of a home 3D printer. I'm testing this on a '73 TB, so it's also nice to have the built-in backup return spring in the TPS. |
