1/32 Deutz-(ish) Gas Mech (Using Bmann Davenport)

Marc:

I'm with Franck on this, leave the cab open. Anything else will end up looking like a caricature I think. Besides, to quote Sir Arthur Heywood, "A stout mackintosh is cheaper and far better for the driver." Good photos Franck, thanks for posting.

No sure about that second one though... maybe Marc could do one of those pulled by a donkey

   I'll remove that Diema photo when Marc put his machine on wheels 

   btw Now Russ is in Colorado, I can show, without troubling him, some antlers, big ones  http://homepage.ntlworld.com/nigel.ford2/_wp_generated/wp61797f3c_0f.jpg

Good one Jacq  . Fortunately topics on this forum tend toward the sublime. With that antler photo we've now captured the ridiculous

How are you going to hide that huge transmission cover with an open cab? Otherwise It looks great. I want to build one! The cast weights came out fantastic, when i tried mine they looked whimpy, way to go, I cant wait to try this method! Cast weights for everyone! I just rememberd I have a Duetz catalog, I will scan it and send it to you

Gil,

I am going to leave the transmission casting, and do some modifications and cast-iron texture to it...I reduced it as much as I could without exposing the space for the worm gear....or without creating a LOT of extra work for me.  I will actually also have to have a decent sized bulge/incursion behind the firewall, in order to hide the rest of the motor & DCC board. This would be less visible/noticeable/offensive in a closed cab version.....will have to see how it plays out with an open cab.


Was too hot to ride today, so I spent some time at the bench, building the rear pilot/frame and coupler set-up.

I wanted to mimmick the European buffer style link & pin couplers, yet have them fit the existing Bachmann Kadee box. In order to do this I modified a set of Foothill Model Works L&P couplers, by drlling out the existing pin hole to .045", and adding a piece of arced .020" styrene sheet to the face.




The pins I used are from PSC and come in brass and plastic. They are well suited/sized for 1/35 or 1/32 scale (and though oversized for 1/48, they could be used in 1/48 for all those whiners that complain about small and plastic pins). The pins are .280" long overall, with a .040" shaft. The pin near the buffer face will be replace in the end with a custom formed pin and chain assembly to macth those I have seen on an Indonesian sugar cane operation.



This is then completed end sill/frame assembly using the original Bmann coupler pocket, and the modified FMW coupler. Note that the Bmann coupler pocket has been drilled through top to bottom with a .045" dia hole, to also accept the coupler pins.




Next...the front sill/frame piece.

can you post a prototype pic, I'm confused....

[marc_reusser]

Of course I can...

The cars/loco are connected to echother by a pin-chain-pin set-up...one pin into the hole behind the face plate on one car...and the other pin into the hole behind the face plate on the other car....the chain connecting the pins then holds the cars together...pretty simple set-up.....sorry I don't have the pic on hand at the moment showing two linked cars...but I think you get the idea.

I hadn't seen that type of coupling before. Neat!

[danpickard]

Marc,
I'm thinking the buffer plate on that coupler sits too high, and thats what had them confused.  I myself was thinking that maybe a hole was yet to be milled out in the middle of the plate.  In the reference pic you just posted, it looks like the link sits across the top of the buffer plate.  Your pin appears hidden behind the plate, and no easy "flat plane" for the link to run across.  Maybe?

Dan,

I think you are correct...I was debating on cutting a notch/depression into the top for the chain to pass through.

I will likely end up lowering/shaving the top a slight bit...and mabe radiusing the bottom a bit more....but FWIW the pin behind the buffer plat is not the one I will be using at that loc. I need to find the pic, but the one I was after had a larger triangular loop and the whole assembly sat up a bit higher from the coupler shaft/top.

  In the link werkbahn.de are plenty of photo's showing an elongated openings in the top of buffers to pass the chain.

Now it makes sense!!!!
Thanks Jacq!

Marc,

I know nothing about the technical side of railways but I do like those couplings .... and even more with the cut out for the pin and chain, you always manage to add something a bit different with your work.

The photo you posted is interesting can you let me know some more details of where you got it

[TRAINS1941]

Marc

Good choice on the couplers.  Different yes but really goes great with build.  But then again you always are looking for the different.

  These puffers are also made with a recess on the top to clear the chain coupling. this is normally a 3 or 4 link chain with a long shackle and or triangular shackle.

  Marc, here a link to a build Deutz model from Ecore. Yuo should be able to camouflage the gear bulge as gearbox. See some photo's of the model.

Hi Marc,

Nice job! I agree with Jacq, these puffers are often made with a recess on the top for the chain coupling...
