Ann Arbor Hutchins End (was FW&D 7231 Accurail kitbash)


Robert kirkham
 

Hi Craig,

Attaching a couple of photos of the first version of the Hutchin ends for the Accurail kitbash.  Here are the issues I see: 
- printed flat, the overall surface is good until one looks at the edges.  They have diagonal striations so would need filling and Archer rivets used to correct the surfaces.
- As you can see, the parts have a flange in back to help locate the sides.  While it fits nicely into the car bottom, up top its a little tight.  So it may be a bit too wide, and so would need to be thinned down by the modeller (or I will edit the drawing once I have it verified.). 
- The gussets at the bottom look to extend downward a little far, so would need to be sanded shorter once installed.  
-  I’m not sure if the ledge for the floor to mount into is the correct depth.  
But, those are all elements I can fix.  So far, pretty pleased with this option.

Looking forward to seeing this one.  Did you get the Shapeways parts for the complete ends yet?  If so, what is your opinion of them?

Those are cool looking parts, Rob!

I think they will make an interesting model.  My kitbash is using an earlier version, and almost ready for priming.  

After getting bogged down by some computer issues, I’ve managed to create improved versions and upload them to Shapeways this morning.  I think they will have fewer issues and be easier to fit into the Accurail body, but will need to test them out.  Here’s the link to the parts for those who are curious:

Rob, where did you find a reference that shows two pressings per panel? Any drawing or photo I've seen shows only one, and lots of separate panels combined to make up the end.

I wish I had drawings Dennis - my version is scaled from photos.  But to answer the panel question, I simply went with what I could see in photos.   When my project started, I referenced the Jim Parker photo in the list photos: https://realstmfc.groups.io/g/main/photo/43681/65?p=Name,,parker,20,1,60,0.   Since then I have found a number of other images in Rob Adams article in Prototype Railroad Modelling Vol. 2.  http://speedwitchmedia.com/product/prototype-railroad-modeling-volume-two/

The Rob Adams article in Culotta's Prototype Railroad Modeling book includes Arnt Gerritsen's drawings of one of the AA 74000-series cars.  A photo of the actual car Arnt and I measured is attached.  While this is a taller car than the one Robert K is modeling, it has the same Hutchins end with an extra panel added at the top.

Sadly our requests to arrange to move/preserve the car once the city DPW was done with it were ignored and the location is now a vacant lot.

If the 7200-series Accurail car this is designed to fit has a 9'2" IH, then a Pere Marquette 86000-series double-sheathed boxcar becomes a reasonable project, using these ends, a Hutchins roof and home-built sides.

Aren’t the double sheathed cars slightly wider at the car ends?

Let me know the dimensions and it might be do-able.  

BTW, a typo crept in below: the Accurail kit the ends currently match is the 4300 series single sheathed cars.  The 7200 car series is the Ann Arbor prototype.

That photo of the Hutchins end with two pressings per panel is a new one on me... learn something new every day. Hutchins must have bought a bigger press before they were forced to end production.

Cool!  It says something about just how splintered the industry was amongst a bunch of manufacturers constantly developing new designs and new capabilities.  I’m reminded of the conversation a few years ago about the different shapes of the ordinary dreadnought end.
