How about "offset" links for different heights? I have some of them because some cars have lower end beams and pockets. 'Twas done on the real ones also.

Well, that's my story anyhow.

Hi Woodie,
Yes you are right and we do have some offset links, but there is a limit how far that you can offset (found out usually the hard way) before you start to jack up a smaller lower wagon when you are moving it - especially when pushing through curves. Get it wrong and you have a derailment that takes time and effort to fix (even when it falls off at walking speed)

Here is the example of the transition coupler that we made up to go between the high-height link and pin Innsifail Tramway wagons and the knuckle couplers of our locomotives

There is a "little bit" of a height mismatch there..but nothing that couldn't be sorted.

Hi John.

Unless I want to totaly bebuild the endbeams on my Bachmann Porter & Shay...
...I might need some of those !!

Can you weld me up a few in 1:35 ?

Hi Si
If you are close to HO standard height in 1:35, then the Porter and Shay should be fine just as they are without having to do a "height fudge"

Hi John.

No, I'm not close to HO std. height.

I have very similar 'proportion' as you mentioned On30/1:48 scale & HO height.
But not the 'actual' same measurements.

I have, more like 1:35n2 scale & Kadee std. On3 height...
...although the actual couplers are not Kadee On3 ones...
...but The San Juan Car Co. 'Evolution' couplers.

'Fudge Bar' needeed !!

:moose:

Si.

Great Wikipedia knuckle-coupler link BTW John.
Pretty much tells the whole story !

Never thought to look there for coupler info.
They do tend to have some good technical pages.
( it's the Celebrity stuff that gets messy ! )

This is The San Juan Car Co. 'Evolution' coupler.





As you can see in the photo, an extremely realistic appearance.

The actual knuckle-spring is concealed as well, inside the coupler body.

Whoever designed this coupler really knew what they were doing...
...compared to the Kadee On3 couplers...
...IMO it is a massive step forward in every respect.

I am constructing my own basic coupler-pockets...
...so the simple mounting hole & built-in centreing-springs are perfect.

Hi John.

I snapped these pics. of the coupler height & size on the new car builds.

I think it looks very 'Victorian Railways' !



The wide-angle lens on the camera, does make the coupler look a bit bigger than seen by eye.

This low shot does as well, even though Wolfgang is only standing 1" away from the knuckle.

I dunno if Michaels 'coupler pocket bodge' remark is causing my insomnia or not.
It could just be the 20 cups of coffee a day !
Mmm...

The coupler pocket above ^^^ left is based on my knowledge of how the Westside Lumber Co. made theirs.
Their car builds were all 'in house' as far as I know.
Based on Pacific Car & Foundry, or similar hardware I believe.

The coupler pocket above ^^^ right is based on a 'between the frame' approach, used by the Gilpin Tram.

I have been making steel (styrene !) underframes of late.
The first for a terribly mooodern WELDED tankcar.
The second for my BROWNHOIST inspired crane project.

I have an absolute TON of research photos of similar cranes now.
The one here, has been selected from the bunch as a good 'template' for my build.

I was about to make a rectangular-hole in the end-beam for the coupler-shank...
...when I noticed that my proto-photo had it's coupler 'bodged ?' on, underneath the underframe.
Mmm...

I am going to see if I can find some photographs of how this might have been attached.
But I wondered if anyone has any pointers as to how this might have been done.

I'm not using Kadee couplers, so no ready made box.
The San Juan Car Co. 'Evolution' coupler as above ^^^ is again being used.

'Evening Si,

The voice in the night whispers --

"Coupler pocket bodge, coupler pocket bodge"..............sleep well, sweet dreams.

If you enlarge the coupler area of the above photo, there is a square shape silhouetted within the far side stirrup step. Maybe a below frames (chassis) coupler pocket bodge ?

Regards, Michael. (Forever in steel, never in styrene; unless it's scenery)

...Or, go with link & pins and forget all that "height" jazz!

Woodie

BTW-the inspiration for my Brownhoist came from the Mich-Cal Lumber Co. There are drawings in the Pino Grande book, page 139.
