Plastic gears

[DadO]

Fixthecopier intrigued me whit his previous post obout part usage and i wanted to ask this a long time a go but i forgot and it was last thing on my mind.

Is there any way to make a plastic gear that broke? Or duplicate broken one?


I talked to some people and one guy told me that he can make same gear if its not broken(eg. missing teeth)

Plastic gears

There are a lot of 3rd party manufacturers and if its a popular machine it might already be in production somewhere. They usually dont like to run small quantities unless the parts are good sellers cause its not worth it for them. So if you're only needing a small quantity you're probably not going to get them. Do you have a part number for the gear?

Once worn or fractured, a Delrin gear is very difficult to repair.

I have heard stories of techs inserting and gluing wedge shaped pieces to restore gear teeth. I think there is quite a lot of embellishment going on in these stories.

To my mind there is too much strain on most gear drives for a glued gear to survive for any reasonable length of time.

I've been buying gears & timing pulleys from them for 15 years. =^..^=

Based on some of my past life, in a machine shop, to make a die to cast a precision gear would not be cost effective unless you bought hundreds of them at best.

If you're at the point where you have a machine with a broken gear and you can't order the gear from the manufacturer any more, then I'm pretty sure that's a sign from God to bite the bullet and put in a Sales lead. Even Plastic-Weld can't fix broken gears...

And the cost of plastic these days is astronomical

I still can't, even with Superglue, I just glue my fingers together and go home.

"They" design the gears to broke over time and when they broke they dont have it in the warehouse...and thats a bad feeling Ordering a mass quantity of gears is a not an option lol...

This close this post

Yes, I've done a "Frank Spencer" as well, I've glued myself to a copier and my mobile phone, fortuantly not at the same time!

And have you had it dry up in the end and then shoot out all over your trousers when you squeezed it hard, thus adhering your trousers to your leg?

I'm talking about Superglue, by the way
