Now, those are some "FAR OUT" gears & chains! If I build another whatzit, I will get me some.

Woodie

The main trouble with the fusee chain is it's so darned expensive for the amount you get.

Hi Guys :wave:


I have got some more info on the new stainless-steel roller-chain I found to Post...

...on other 'puter.

The Delrin(TM) chain is still the favorite though IMO.


I thought I may as well Post this pic. of the Tamiya 1:12 motorcycle chain I found as well.

It is probably useless for trains...

...cos like the fusee chain, I don't believe suitable 'train size' sprockets are available for it.

I don't think it can easily be split/joined either.

I guess it MIGHT actually function, but I don't know that either.

Possibly not, since it is obviously an 'aftermarket dressup' for the Tamiya 'static' bikes.

Probably mainly intended to look good.


Damn expensive as well !

Makes fusee chain look like costume jewelry !! :shocked:






I did actually make a Tamiya 1:12 touring bike years ago.

Although 1:12 scale, the model isn't really THAT big.

The driver figure being only 6" tall.

In remembering that bike model, which I no longer have...

...the chain in the above photo ^^ DOES look incredibly small & the bike incredibly detailed.

It looks like the wheels have REAL spokes ! :shocked:

Mmm... my tourer of 30 years ago never had that.


:!:


Si.


Back on the chain-gang with more chain chatter   l  a  t  e  r  .  .  .

Sure.  It is for a monorail but could probably be adapted to a two rail system.  Like I recently told a potential customer who asked about hill climbing, "WhisperJet is mainly for speed (and quiet), not for pulling power".  The overall reduction ratio is about 13:1.  The pulleys are 3D printed except for the aluminum motor pulley (Parma slot car part).

ServoCity also sells the delrin chain and sprockets. I used some for a work project and found the chain links have to be carefully inspected, some have burrs or molding flash that keeps them from operating smoothly.

One item of interest is their servo sprockets, could be used for a nice slow speed drive.
