From what I have heard it's the gearbox shell that is plastic, not the actual parts in the gearbox (gears, bushings, springs, etc.)

Besides looking ghey in all that purple and pink gear? I didn't say it was cheap...but its quiet..and requires no maintenance..

  Actually Delrin can come in quite the variety of colors these days.  Although, some colors are more expensive I hear (don't know if that's true though).

  Besides, if it was as cost capable as metal gears, I could care less what color they are.  It's not like people will see them.

I use delrin all of the time when Im making things. I think I still have two 3ft sections of 1" roundbar left. (I got them for free )  Delrin is probably one of the hardest types of plastic that there is. It machines like a dream, except for the somtimes nessicary oversizing when boring a hole. The stuff I have is a reddish brown color. I also have pieces of nylon roundbar, and teflon roundbar. The delrin is probably the hardest that I have, but it is pretty brittle. If you take a piece and smack it with a hammer, it will fracture and even shatter. You can always tell when you are machining a hard type of plastic like delrin or nylon, because it has a certain smell when you cut it.  But it is really easy to machine, and it leaves a great finish after each pass.

Exactly, it's just the shell.  Where'd you guys get plastic gears from?

I was saying i was talking to someone about MAKING some Delrin gears..

Mugen's very next post after my first one.  I want to know where plastic gears and internals came from.

I think it was a simple misunderstanding.  Mugen took “a new mechbox that is made out of really, really strong plastic that can handle more stress then a metal one.â€￾ To mean that the entire gearbox was made of plastic, not just the shell.

Although I doubt it, it is possible that the Star gearbox has some plastic parts that are traditionally metal (other then the shell). As far as I know there are not really a lot of details known about it yet, and the information on the Star site is confusing at best.

When I used to race RC cars, they made pinion gears (the big ones) out of delrin..s*** was expensive..but worth it..quit as hell, required almost no lubing and extreemely small..For those who don't know about it..Its CNC machined plastic/nylon. I was talking to a few people last week...about maybe having an all DELRIN gearbox...for those who want silence, this would be the ultimate.. IT would also require no lube...which is nice and keeps the gearbox clean.. Im  sure you know what Delrin is Dave, you work in automotive.

i had remote controlled cars... i used to put lighter fluid on them set them on fire and drive them around until they stopped. kinda like an rc meteor.

That is pretty sweet Surplus. You just gotta watch out for the battery compartment...BOOM!
You can go to the dollar store and pick up those cheap r/c cars for like a buck and use those for your meteor car ^_^ .

:roll: Does that have anything to do with the topic at hand?
