Hi Southpier :wave:


Thanks very much for the links. :brill:


The Gizmoszone gearhead-motor, the diameter of a PENCIL ! :shocked: is the smallest I've seen !


SDP-SI also have the SMALLEST Acetal-chain I've seen, with a pitch of only 3.117mm :shocked:




&

This page is just simply INCREDIBLE ! :bow: linked from nigellawton009.com

:thumb:


Well...

...my now, only 2nd smallest, chain & sprocket 'look-see' arrived today.

I was actually quite impressed, until I saw Southpiers SDP-SI link !

The chain, which is the same as 'Serv-O-Link', is not exactly MEGA slim, as suspected...

...BUT it is acceptable in 1:35, just, if you think your prototype may have used slightly 'chunky chain'. :P


The SDP-SI chain def. warrants further investigation though.

I haven't checked out matching sprockets for it yet.

The price of the SDI-SI chain/inch, is similar to the chain I just received.

However, the larger minimum-order + P&P from the U.S. means the price tag is a tad 'Rolls Royce'...

...but it does have the top-step on the podium, for micro-chains so far !


In wonder if I can find a U.K. supplier for this teeny-weeny stuff ? L:


:moose:


Si.


EDIT :- :doh: I just measured the chain I received today...

...in fact, it seems that this chain, probably Grandt-Line, Serv-O-Link, and SDI-SI chain...

...are all exactly the same product !


So IS ? this as small as it gets ? ???

.

For really tiny chains, there are the Hiroboy motorcycle model roller chains in 1/12 scale.
http://www.hiroboy.com/112_Motorcycle_Chain_Set__P941--product--2135.html

You build them up yourself on a former from metal links on nylon rollers and whist it's a right faff for those like me with thick fingers, they come out very nicely.

I used them on my Stunted Goose and whist they are only cosmetic on there with the gears free-wheeling on their axles (you don't want to put any more strain than necessary on a Bachmann rail truck back axle!), I see no reason why they shouldn't work in practice.

Hi Doug :wave:


Thanks very much for that info.

I like the Goose ! :bg:


I had only seen the pre-assembled Tamiya 1:12 motorcycle chains before.

It does look like an interesting product.


I see from their website...

...the idea is to assemble the metal-links on the plastic-rollers...

...& then 'melt' the ends over, with a soldering iron...

...and then cut the rollers loose, I guess.


A clever idea & looks good for realistic 'chain sag' etc.

But actually work ?

I suspect if it was possible to get it in motion...

...it would expire pretty quickly.


My problem is that for my insane idea...

...I will need 16 or 12 sprockets as well !


I can see how darn small it is though...

...standing on your, Code-83 rail ?, I think. :shocked:


I thought I was a moaning ol' grouch, assembling 1:35 Caterpillar tracks !

Were you a micro brain-surgeon before retiring Doug ? ;)


The Victorians got workhouse kids to assemble pocket-watch 'fusee chain' apparently.

Too many Health & Safety regs. these days for that though...

...they could pass a bill to bring back workhouses I suppose.

They're probably drawing one up as we speak !


:moose:

I gotta say actually...

...the 3.117mm pitch Acetal/Delrin(TM) chain is quite incredible !


I just have a 2" long tester at present.


If you try & 'twist' it end-to-end ... You basically CAN'T !

Yet EVERY SINGLE LINK is 100% free to pivot on the next.

That is some kinda precision moulding, or what ?


:brill:


Si.

Hi Si. I wasn't suggesting it as an option for you, too small and as you point out, probably too fragile. It's just another source that might float someone's boat. Yes, you do melt the roller ends once the link is in place and then when all are done, cut the complete chain from the roller jig.

And whilst I would have loved to have had the dexterity of a brain surgeon or even a troop of workhouse kids who could do what those very talented folk in China seem to manage, I had to do with sets of very pointy tweezers and a lot of bad language!

P.S. I'll tell a bit more about the Stunted Goose build on the Updah thread at some time.

Hi Doug :wave:


It may not be suitable for using with 16 or 12 sprockets.

But if I ever try one of the 'pencil' gearhead-motors that Southpier pointed me to...

...who knows what could be possible with the 1:12 motorcycle chain ?


It could easily work on a simpler drive train.

Main drawback might only be, getting enough of the right sized sprockets.


Thanks again for Posting it Doug.

It is the smallest chain I've seen so far.


It's in the arsenal of top-tricks & before it wasn't.

Precisely why chucking up crazy ideas & questions on Freerails ALWAYS pays dividens.

People have always discovered ways & means that one doesn't always know about.

This photo kinda shows a bit better, the 'real' size of the 3.117mm pitch Delrin(TM) chain & sprockets.



:)

The paperCLIP photo, on the previous << Page...

...is a fair representation of the drive components size, next to a NORMAL paperCLIP. :mex:





The cyclists in this photo are obviously WAY under scale. :P  (_!_)  ;)
