Repair vcr crack gear???
I have a multi system sharp vcr, and recently it refused to eject the
tape. I found out the gear at the motor drive shaft that is responisble for loading and ejecting the tape is crack. However, i am unable to find replacement gear. The gear is a bit small, and using the krazy glue still can't make a tight gear. Is there anyway to repair the gear? any suggestion? Thanks! |

ps.com... I have a multi system sharp vcr, and recently it refused to eject the tape. I found out the gear at the motor drive shaft that is responisble for loading and ejecting the tape is crack. However, i am unable to find replacement gear. The gear is a bit small, and using the krazy glue still can't make a tight gear. Is there anyway to repair the gear? any suggestion? Thanks! There is a couple of tips relating to repairing broken plastic gears somewhere on my 2 tips files on URL below -- Diverse Devices, Southampton, England electronic hints and repair briefs , schematics/manuals list on http://home.graffiti.net/diverse:graffiti.net/ |

In 25+ years experience, I have yet to discover an effective and lasting method for bonding nylon to itself. There is no way. Nylon is molded 100% bone dry and absorbs moisture after that. Once absorbed, no weld is possible. Unless you can mechanically repair it you are screwed. -- .. .. .. .. .. .. .. .. |

Repair vcr crack gear???
I've had to make many gears and misc. parts.
Go to your nearest hobby shop and buy some Alumalite plastic. It's a two part liquid plastic that you mix together and it is completely set and hard in 3 minutes. They also make a rubber casting compound to copy the original gear with. I've been using it for years to make gears and other parts for older copiers and such. Ray L.

Once absorbed, no weld is possible. Unless you can mechanically repair it you are screwed. I used to weld nylon gears in hotel TVs all the time when I didn't have spares, and not one cracked again. I even still have a 30 YO Sanyo Sears with a small gear that had lost some teeth. The new teeth I welded on have held up for at least 10 years now, and I was rough on that tuner, wearing holes all the way through some of its contact fingers. |
