The Dinky Creek bridge
Posted by Graffen on Saturday, July 07, 2018 12:57 PM

Recent build.

 

Sorry, no construction images. My memory card did not want to find them....

Wood structure kitfrom Scale Structures limited.

The Dinky Creek bridge in HOn3.

All rivets and fittings are in metal .... Painting all the metal parts and drilling holes for 600+ NBWs is a bit of therapy.

Nice work!  I picked one up at a swap meet a few years back to use on my circa 1910 anthracite road.  For now, its still "sticks-in-the-box" waiting for layout construction to catch up.  

But I do have one question... prototypically speaking - would such a small bridge be able to handle 30-40 ton hopper-gons and medium sized consolidations?  If not, I'll build it for horse and buggy traffic.

WOW! I really like it.

Talk about a little model with tons of character. Very nice build.

Happily modeling the STRATTON & GILLETTE RAILROAD located in a world of plausible nonsense set in August, 1954.

SS Ltd claims that the inspiration was a narrow gauge bridge over Dinky Creek in California. There is a similar bridge of this type there but it was a highway bridge built in 1938: https://upload.wikimedia.org/wikipedia/commons/b/b3/Dinkey_Creek_Bridge.jpg  from https://en.wikipedia.org/wiki/Dinkey_Creek_Bridge

For loads as you describe I would change the bottom chord. For higher loads I would avoid the many splices in the tensile member and use longer timbers with fewer splices like in a Howe truss bridge.

The arched top chord needs these splices for the shape anyway. Pressure joints are easier as one can make them form-fitting the contact load transfer.

Scaling off the photo, I get a clearance of about 9 1/4 feet.  That's too narrow if you're doing standard gage.

In my opinion.

 

Looking at the Wikipedia photo, it does look like a nice lightweight road bridge, though.  Single lane, of course.

Really nice bridge Graf, but I think you have one thing wrong:

That is not therapy! After doing that is when you need therapy! Start with a shoulder massage, and then maybe move on to an Opthamologist to get your eyes straight again! Smile, Wink & GrinLaughLaughLaugh

Ah, shucks... That's why I have a wonky eye.

The backrub is sorted out though. SWMBO is quite handy.
