Steel cable transmission

[Hauk]

Hello Peter,,
I beam basically all metal parts with aluminum oxide grain 180 with about 1 bar air pressure.
Then all the parts are immediately blackened with chemistry.

Pretty nice work as usual!

What brand of blackening fluid do you use? It is getting more and more difficult (almost impossible, in fact) to order my dear Casey Birchwood fluids from the US or the UK.
So i am looking for other brands that might be availble locally.

Could also ve nice to know what the "real" purpose for your blackening medium is. Maybe I then could find something similiar.

Hello Hauk,

thank you, yes I always try to just do my best.

The chemistry that I use to blacken is commercial and not available anywhere.
I have received a detailed work instruction with safety instruction and had satisfied none of the chemicals to pass.

Hi Hauk

Carrs do metal blackening fluid but I've not tried it.  You can get it from C&L finescale in the UK

Edit, my local gun shop stocks gun blue, http://www.brierleyguns.com/cgi-bin/ss000055.pl?page=search&PR=-1&TB=A&SS=Gun+blue&ACTION=Go%21

Please consider the steel and non-ferrous metals require completely different chemistry.

Thanks Jim!
In fact, Birchwood Casey is my prefered poison, but it is impossible to order it from the UK due to the restictions on what you can ship by air. It used to be possible to order it from Eileens Emporium, but no more. I have found a Swedish gunshop that sells the stuff, and have tried to place an order. With a little luck, they will ship it...

Peter, those bearing supports and that gear are wonderful! And Helmut's winch, I really admire you guys who can fabricate things so well.

All the followers of this thread might remember that I was a litte bit fed up with my gear wheel production. This is precisely what happened and so I had to stop for a rest. And so the temptation to create some commissioned work for a aftermarket model company seemed to come along just at the right time. Suddenly I found myself torn between a new challenge and the long and lengthy gear wheel production.
While doing a lot of reasearching for the new work I had to realize, that the effort for this would be much too high. So I cancelled it after more then a half year and returned to my currend project and ...




... my gear wheel production. This is the current status (9 of 16!!!).


And the gear theeth fit very well although I have no machinery to work with 



The gear wheels of that differential are a particular challenge. My third attempt:


Hope you like it!

The gears look most satisfactory. -- Russ

[Chuck Doan]

They look excellent Peter! Your over half way there! Zen gearwork.

[Ray Dunakin]

Incredible work on those gears! Hard to tell they are handmade and not machined or printed.

[Sami]

Very nice weathering Peter !

[Peter_T1958]

Thanks for your comments!
And it works - these pictures show a first mounting without axle bearings. Surprisingly, the differential gears even could be moved as the teeth interlock not so bad.



I decided to fix the cast pillars prototypically: Threaded brass rods of 1.3 mm diameter are glued in deep boreholes in the abutement. Of course the bolts and rods have to be blackened in a next step.



Yes, I am taking just small steps forward, but modelling is fun again 

Cheers, Peter

Peter, It's great to see you back modeling on this project again. Even the smallest steps are done so well.

[finescalerr]

Coming along nicely. -- Russ

Peter just a great, interesting project for me, please report on.
